Abstract: |
A summary of research results on assimilation of GOES (Geostationary Operational Environmental Satellites) Imager observations into a cloud resolving model will be presented. The purpose of the research is to evaluate feasibility of atmospheric data analysis with clouds. The studies were performed using a research data assimilation algorithm designated Regional Atmospheric Modeling and Data Assimilation System (RAMDS) that was developed at CIRA (Cooperative Institute for Research in the Atmosphere) at CSU (Colorado State University) and at ATOC (department of ATmospheric and OCeanographic sciences) at CU (University of Colorado). In RAMDAS a fully nonlinear 4DVAR (4- dimensional variational) data assimilation approach is applied to the cloud resolving regional model RAMS (Regional Atmospheric Modeling System) that includes explicit bulk parameterization of cloud processes. The observational operator for GOES imager observations is a system for computing unpolarized radiative transfer for either collimated solar and/or thermal emission sources of radiation in both clear and cloudy plane-parallel conditions. Adjoint models of the cloud resolving and radiative transfer models include explicit linearization of these nonlinear models. Overall, the results with RAMDAS indicate that the data assimilation of the cloud affected geostationary observations is feasible. The results show improvement in the model representation of the cloudy atmosphere and consistent change in the dynamical cloud environment. |

Abstract: |
The seminar presents the current status of the Polar Communications and Weather (PCW) mission, led by the Canadian Space Agency. As the name indicates the dual goal of PCW is to provide continuous communications and Earth observation services over the Arctic, this with a near real time operational mandate. Environment Canada will take responsibility for the production and delivery of meteorological products. Currently in the middle of Phase A, the mission is planned for 2016. The seminar focuses on the meteorological component. PCW is defined by a constellation of two satellites in a highly elliptical 12-hour “Molniya” orbit with apogee at ~39,600 km and perigee at ~600 km. The constellation will provide for the first time seamless observations over the entire circumpolar domain above 55 N. The main meteorological instrument is an advanced imager with characteristics similar to those of the imager planned for GOES-R (2015) or Meteosat Third Generation (2016). The PCW imager has 20 channels covering the spectral range 0.45 m to 14.4 m, with pixel sizes ranging from 500 m to 1 km for visible channels to 2 km for infrared channels. The presentation will cover the following elements: imager definition and applications, orbital characteristics, critical technology issues, production of simulated datasets, data assimilation and impact studies, notably in relation to atmospheric wind vectors, and opportunities for other instruments. The international context will also be presented. For example the World Meteorological Organization (WMO) is supporting the highly elliptical observation concept, and several countries have indicated a marked interest for PCW. This interest stems from the fact that the mission allows extending the applications developed for geostationary satellites all the way to the North Pole. |

Abstract: |
The Ocean Project advances ocean conservation in partnership with zoos, aquariums, and museums. Part of its work is to conduct market research and strategic communications tools for its Partner network of 1,000 institutions and organizations. This presentation will focus on the market research that The Ocean Project completed this past year. It’s the single largest, most comprehensive public opinion research project ever undertaken on behalf of any environmental concern – with findings that are helping those in the ocean conservation community connect more strategically with the public for positive change. With support from NOAA through an Environmental Literacy Grant, the national study was conducted for The Ocean Project by IMPACTS in collaboration with the Monterey Bay Aquarium and the National Aquarium in Baltimore. This study was completed in November 2008 with responses by 22,000 American adults. Additionally, The Ocean Project completed the first of four semi-annual tracking surveys in September 2009. The tracking surveys are helping measure changes in opinions and test messages to the public. This presentation will provide an overview of the research findings, implications, and how The Ocean Project Partners and others are using the findings to improve ocean literacy. |

Harmful Algal Blooms and Possible Effects on Fraser River Sockeye Salmon
|
Date/Time/Location/Seminar Sponsor: |
Thursday, 21 January 2010; 11:00 - 12:00 PST [Check U.S. Time clock for your local time] (Seminar location: Auditorium, Northwest Fisheries Science Center, Seatlle, WA; OneNOAA Science Seminar sponsored by: NWFSC) |

Abstract: |
Recruit per spawner of Fraser River sockeye salmon has declined precipitously over the past 20 years and in recent years total run size has reached record low levels for our modern era, despite more than adequate escapement of many stocks. Although in-river mortality of returning adults is a problem, much of the recent decline has been attributed to unexplained marine mortality. Ten years of weekly algal bloom monitoring data by the B.C. Harmful Algae Bloom Monitoring program within four regions in British Columbia, from southern Strait of Georgia to Queen Charlotte Strait, were compared to marine survival data for the only sockeye stock that has smolt outmigration monitoring (Chilko Lake). For juvenile fish and timing, there was a modest inverse correlation between survival data and bloom intensity/duration of the fish-killing alga Heterosigma akashiwo in the southern Strait of Georgia. In particular, Heterosigma blooms in 2006 and 2007 were much earlier and extensive than normally observed in prior years and fish kills of farmed and wild fish were recorded in North Puget Sound along with warmer-than-normal water temperatures. These early blooms possibly affected juvenile sockeye outmigrating in May and June. Run sizes for these juveniles as adults two years later, in 2008 and 2009, were near record lows.
Adult fish may be adversely affected too, as northerly diversion rates have generally been high through Queen Charlotte and Johnstone Straits since 1991, areas known for midsummer and later Heterosigma blooms. In some years, either the test fishing data and CPUE models that predicted large abundances of adult sockeye passing through Johnstone Strait were in error or the fish subsequently disappeared in the Strait of Georgia. Bloom duration and intensity during July and August, a period of inshore adult sockeye migration in the Southern Strait of Georgia, were inversely correlated with total sockeye salmon run size. Previously it was thought by many that these blooms only killed farmed fish. However, repeated observations of at least some dead wild fish during blooms in both Washington State and British Columbia; the identification of probable sublethal, chronic-exposure effects on fish; the recognition that the alga is not always surface oriented; plus the fact that bloom-killed fish usually sink in temperate waters could all account for overlooking this possible cause of fish loss in the past. Co-occurring food-web processes that could contribute to the sockeye decline are also considered. The presentation concludes with a review of available tools to further assess the situation and possibly mitigate the damage should harmful algae be further implicated.

Dr. Tineke Troost (Lead Scientist, Sea and Coastal Systems, Deltares, Delft, The Netherlands) |
Abstract: |
In the past, mass mortality events of mussels have occurred in the Easterscheldt estuary (the Netherlands), which were due to the explosive growth of harmful algae. Also, these algae lead to foam formation on beaches. Therefore, an early warning system (FEWS) was set up to supply water managers with information on the actual and expected developments of harmful algal blooms in the Dutch coastal waters. The system combines information on field data, satellite remote sensing data and model data, and results are compiled in information bulletins that are distributed to the water managers twice a week during the spring bloom season. |

|
Speaker(s): |
Dan White (Alaska Center for Climate Assessment and Policy) |
Abstract: |
Many communities in Alaska are faced with multiple threats to
infrastructure and quality of life due, in part, to projected changes
in precipitation, temperature, and related incidences of flooding and
erosion. Decision-makers must determine how best to manage their
community's vulnerability with the knowledge that future environmental
change is uncertain. This webinar will discuss a newly released report "Decision-making for at-risk communities in a changing climate" prepared by the Alaska Center for Climate Assessment and Policy. The
report is intended to inform decision-makers relating to climate
change and uncertainty, risk management, and relocation planning.
Issues addressed regarding the planning process for relocation focus
on the steps from planning through execution, perspectives on
community engagement, partial relocation, site development costs, and timing. Sustainability recommendations focus on defining
sustainability, future energy planning, planning for a changing cost
of living, and available transportation corridors. Join this webinar
to learn more about decision-making for at-risk communities in a
changing climate. |

Abstract: |
On October 7, 2009 the Office of Management and Budget (OMB) released a memo on “Increased Emphasis on Program Evaluations.” The message was familiar: the government wants to invest in what works, and that requires programs and agencies that can demonstrate results. How different programs and agencies go about demonstrating results will, of course, vary. I want to raise the possibility that NOAA might adapt some elements of its Ecosystem Approach to Management of coastal and marine resources to address OMB’s increased emphasis on evaluations. What would such an Ecosystem Approach to Performance Management look like and (how) might it work?

Ecological Consequences of Patchiness in The Coastal Ocean |

Speaker e-mail(s): |
kbenoit@coas.oregonstate.edu |
Abstract: |
In the ocean, most resources are heterogeneously distributed and highly dynamic. This patchiness in time and space has significant consequences for population dynamics, trophic interactions, community organization and stability, and the cycling of elements. Recently discovered plankton thin layers (less than 3 m thick) are an extreme case of biological heterogeneity. Our work on thin plankton layers in a variety of habitats including Hawaii, Monterey Bay, and the Oregon coast have now provided the first evidence of trophic interactions in thin layers, shown that biological processes, rather than physical phenomena, can dictate the structure of thin layers, and provided evidence of ecosystem impacts disproportionate to their biomass. By quantifying the relationships between thin plankton layers and their predators, we were able to examine the relative importance of biomass and patchiness in the regulation of a pelagic marine food web. We found that the number and intensity of aggregations at each trophic level rather than the biomass in each step of the food chain involving phytoplankton, copepods, mesopelagic micronekton, and spinner dolphins (Stenella longirostris) were the most significant predictors of variation in adjacent trophic levels. Our results are in accordance with resource limitation - mediated by patchiness - regulating structure at all trophic steps in this ecosystem as well as the behavior of the top predator. The importance of spatial pattern in ecosystems has long been recognized and its effects on predator-prey pairs has been examined in a number of previous studies, however, patchiness as the dominant force regulating an entire system has not been previously demonstrated. |

About the speaker(s): |
Dr. Kelly Benoit-Bird, an Associate Professor in the College of Oceanic and Atmospheric Sciences at Oregon State University, is the author of more than 30 journal publications applying acoustics to study the ecology of pelagic ocean ecosystems. Her work examines a wide range of animals including zooplankton, fish, squid, and marine mammals, in all cases emphasizing the mechanisms creating spatial and temporal dynamics in pelagic marine ecosystems, the effects these dynamics have on interactions between organisms, and the mechanisms animals use to cope with these patterns. She has been involved in the development of several new optical and acoustical instruments and has made fundamental acoustical measurements of a variety of species in the process of addressing ecological processes in the ocean. Dr. Benoit-Bird’s work was recently recognized by the Acoustical Society of America with the 2009 R.

Dr. Qinyu Liu (Professor of Physical Oceanography Laboratory, and Ocean-Atmosphere,
Interaction and Climate Laboratory, Ocean University of China, Qingdao, China) |
Abstract: |
The authors investigate the relationship between Sea Surface Temperature (SST) in the tropical Indian Ocean (TIO) and the seasonal atmosphere circulation in the Asian Monsoon Region (AMR) using the Maximum Covariance Analyses (MCA). The results show that the Asian monsoon circulation is significantly correlated with two dominant SST anomaly (SSTA) modes: the Indian Ocean Basin Mode (IOB) and the Indian Ocean Dipole Mode (IOD). The peak SSTA of the IOB appears in spring and has a much stronger relationship with the Asian summer monsoon than the peak of the IOD does, while the peak SSTA for the IOD appears in fall and shows a stronger link to the Asian winter monsoon than to the Asian summer monsoon. In addition, the IOB in spring has relatively stronger link with the atmospheric circulation in summer than in other seasons. The large-scale atmospheric circulation and SSTA patterns of the covariability of the first two dominant MCA modes are described. For the first MCA mode, a warm IOB persists from spring to summer, and the atmospheric circulation is enhanced by the establishment of the climatological summer monsoon. The increased evaporative moisture associated with the warm IOB is transported to South Asia by climatological summer monsoon, which increases the moisture convergence towards this region, leading to a significant increase in the summer monsoon precipitation. For the second MCA mode, a positive IOD possibly corresponds to weaker Indian winter monsoon and more precipitation over the southwestern and eastern equatorial TIO. |

Abstract: |
The Small Business Innovation Research Program for FY 2010 is a NOAA Program for which a solicitation just opened on October 14, 2009 and closes on January 14, 2010. Program objectives include stimulating technological innovation in the private sector and strengthening the role of small business in meeting Federal research and development (R&D) needs. The SBIR Reauthorization Act of 2000 requires the DOC to establish a three-phase SBIR program by reserving a percentage of its extramural R&D budget to be awarded to small business concerns for innovation research. There are three SBIR phases: Phase I is the for Feasibility Research and the purpose is to determine the technical feasibility of the proposed research and the quality of performance of the small business concern receiving an award. Phase II is for Research and Development prototype development in which only firms that are awarded Phase I contracts under this solicitation will be given the opportunity to submit a Phase II proposal. Phase III is intended for commercialization and it's intended that non-SBIR capital be used by the small business to pursue commercial applications of Phase II. Consultative arrangements between firms and universities or other non-profit organizations are encouraged, with the small business serving as the prime contractor. CoRP/SCSB serves as the focal point for the NESDIS SBIR program. It is the purpose of this presentation to inform NESDIS scientists and managers about the SBIR program, how it can help move forward new and innovative ideas within the organization, and then discuss strategies to solicit more subtopics for the 2011 solicitation notice which is due in the spring of 2010. |

Wednesday 03 February 2010; 11:00-11:45 ETZ [Check U.S. Time clock for your local time] (Seminar location: SSMC-3 (1315 East-West Highway, Silver Spring, MD, 20910), 2nd Floor; OneNOAA Science Seminar sponsored by: NODC NOAA Central Library) |
Speaker(s): |
Dr. Jon D. Miller (John Hannah Professor of Integrative Studies at Michigan State University) |
Abstract: |
Professor Miller will discuss his analyses of leadership attitudes and public attitudes toward climate change and the challenges of effectively communicating scientific concepts and data to these audiences. For more than two decades, Professor Miller has conducted national surveys of science policy leaders and American adults on a wide array of scientific and technological subjects, and he has collected measures of both scientific literacy and substantive policy attitudes over this period. He continues to collect new information from both of these populations. In this presentation, Professor Miller will suggest that on issues that are scientific and technical in character, the process of policy formation involves a dynamic interaction between policy leaders and citizens who are attentive to the issues involved. It is important for policy and communications planners to understand the structure of the public policy process in regard to issues that are partially or substantially scientific, and he will outline a framework for thinking about this process. The presentation will involve a short PowerPoint presentation followed by a period for discussion and dialogue. |

How U.S. Technology is Revolutionizing the Design of Recirculating Aquaculture Systems (RAS)
|
Date/Time/Location/Seminar Sponsor: |
Wednesday 03 February 2010; 12:00-13:00 ETZ [Check U.S. Time clock for your local time] (Seminar location: SSMC-3 (1315 East-West Highway, Silver Spring, MD, 20910), 2nd Floor; OneNOAA Science Seminar sponsored by: NOAA Aquaculture Program in cooperation with the NODC NOAA Central Library) |
Speaker(s): |
Dr. Ronald F. Malone (Chevron USA Professor, Louisiana State University) |
Abstract: |
This presentation will describe technical advances leading to a new design for Recirculating Aquaculture System (RAS) being used in commercial aquaculture facilities in the United States. In addition to efficient water treatment, this new technology supports critical design objectives for large-scale recirculating systems including low water loss, solid waste reduction or reuse, energy conservation, and long term economic sustainability. The most energy efficient RAS designs now operate without mechanical pumps. Instead, these new systems use air blowers and airlifts to create the hydraulic head needed to move recirculating water through floating bead biofilters. An ongoing investigative program with funding from NOAA Sea Grant and the U.S. Dept. of Agriculture has demonstrated the application of this water-conserving RAS filtration approach in marine finfish applications. Development of high volume, modularized closed marine RAS fingerling production facilities are viewed as critical to the development of a commercially viable finfish growout production industry based on netpens, ponds, or RAS technologies. |

Speaker E-mail: |
shannon.bettridge@noaa.gov & greg.silber@noaa.gov |
Abstract: |
Perhaps long underestimated as a factor in large whale recovery, collisions with large vessels are now regarded as a significant threat to several endangered large whale populations. Vessel collisions, or “ship strikes”, is one of the main causes of death for the highly depleted the North Atlantic right whale. Their vulnerability to ship strikes is compounded by exposure to human activities near population centers in waters along the U.S. and Canadian east coasts, slow swimming speeds, and a natural positive buoyancy. In a population consisting of only 300-400 individuals, an average of about two right whales are struck and killed by vessels annually. Drs. Shannon Bettridge and Gregory Silber will discuss NOAA’s management actions and some research advances in the course of the last decade aimed at reducing the threat of ship strikes to right whales and other large whales. The talk will include two presentations made at a recent international conference. |

Abstract: |
The ECMWF forecasting system continues to be world leading in terms of forecast performance in the medium range. Both the deterministic and probabilistic forecast products are continuously improved; in early 2010 a new model version with an increased spatial resolution is being introduced, which will help to maintain the positive performance trends. Research is focused on new data assimilation techniques, improved description of physical processes and development of enhanced ensemble prediction methods. Monthly and seasonal forecasts are also produced; the current El Nino event was predicted more than a year ago. Re-analyses are regularly produced and updated. In recent years the re-analysis shows global temperature trends over land areas that are significantly warmer than results from other data sets suggest. |

Abstract: |
Genetic studies indicate that the Hawaiian monk seal diverged from its Mediterranean cousin 10-13 million years ago. At some point, it colonized the Hawaiian archipelago, but beyond that, very little is known about its early history or the first human-seal interactions. There is no mention of the species in the Kumulipo, the ancient Hawaiian chant of creation. The first description of the Seal was in 1807, when Lisianski explored the Northwestern Hawaiian Islands. By the end of that century, the Hawaiian monk seal had been hunted to near extinction. The extremely low genetic diversity of the species offers some clues to its past and raises concern about its future. Dr. Jennifer Schultz will speak about previous research on the genetic diversity and stock structure of the Hawaiian monk seal and describe current efforts to understand the seal’s mating system, diet, and its susceptibility to infectious diseases. |

Abstract: |
A series of airborne hyperspectral remote sensing campaigns were conducted from 2002 to 2005 at five U.S. estuaries: Apalachicola Bay, FL; ACE basin, SC; Grand Bay, MS; Delaware Bay, DE; and Chesapeake Bay, MD. 151 field stations were occupied within the flight tracts where the following were obtained: (1) water reflectance R(λ) spectra were acquired by a pair of ocean optic 2000 spectroradiometers, simultaneously, the concentration of (2) chlorophyll a and (3) total suspended solid, and the (4) absorption of colored dissolved organic matter (CDOM) were measured at these stations. A principal component analysis was conducted to characterize the general variability of these water reflectance R(λ) spectra, and explore the factors that drive the variability of water reflectance in optically complex coastal environments. The results suggested that water reflectance spectra in turbid estuarine waters are the results of complex interactions of phytoplankton pigments, total suspended solids, and CDOM. The first principal component, which represents 72% of total variance of R(?), is strongly affected by scattering of total suspended solids and the absorption of CDOM at the green region of spectra; while the second principal component represents 20% of total variation of R(λ) spectra is mainly driven by phytoplankton biomass e.g. Chl a concentrations in red and near infrared spectral regions. Furthermore, the results of this study could provide a framework for using hyperspectral remote sensing as a cost effective method to characterize water quality in optically complex coastal waters. |

Speaker e-mail(s): |
kimberly.murray@noaa.gov |
Abstract: |
In this presentation I review an approach to estimating bycatch of threatened and endangered sea turtles in Northwest Atlantic waters and describe how bycatch estimates are used in fisheries management. Computing robust bycatch estimates can be difficult due to the rare nature of sea turtle bycatch events and low sampling levels. Datasets typically have excess zeros in the data, and there is low power to detect significant effects when analyzing bycatch rates. Using a case study of loggerhead (Caretta caretta) sea turtle bycatch in the U.S. Mid-Atlantic sink gillnet fishery (Murray 2009), this presentation reviews some of these analytical concerns and approaches to dealing with uncertainty. In this study I developed a Generalized Additive Model to describe bycatch rates of loggerheads, and then applied this model to commercial fishing effort to identify times and areas where conservation efforts should be focused. Finally, I describe how bycatch estimates are typically used in Endangered Species Act (ESA) Section 7 consultations and efforts by colleagues at the NEFSC to put sea turtle bycatch into a broader population context.

Abstract: |
The Global Observing Systems Information Center ( GOSIC), initiated in 1997 at the request of the Global Climate Observing System (GCOS) Steering Committee (see http://www.wmo.int/pages/prog/gcos/Publications/gcos-39.pdf), responds to a need identified by the global climate observing community for easier and more effective access to observational climate data and information. GOSIC manages an online portal providing an entry point for users of climate-related global observing systems data and information systems. Following its initial development and implementation at the University of Delaware from 1997 to 2006, the U.S. National Oceanic and Atmospheric Administration's National Climatic Data Center (NCDC) assumed operational responsibility for GOSIC on behalf of the international climate observing and data user communities. The goal of GOSIC is to provide basic user services, including a description of the systems and their data as well as a tailored search capability that facilitates access to a worldwide set of observations and derived products. GOSIC's unique value is its ability to quickly link users, via a consistent and user-friendly interface, to a wide range of data sets that reside at multiple data centers; the GOSIC portal ( http://GOSIC.org) provides users with links to data, metadata, other search tools, and related climate-observing information. |

An Assessment of Living Marine Resources and Chemical Contamination of Vieques, Puerto Rico |

Abstract: |
From 1941 to 2003, the U.S. Navy utilized a significant portion of the island of Vieques (Puerto Rico) for military exercises, including significant use as a bombing range. There has been significant concern among the local population about environmental contamination related to military activities on the island. This study presents an island wide quantification of living resources and contamination in the marine environment. It also serves as a baseline which can be used to help assess the impacts of future development on the marine environment of Vieques. In 2007, sediments were collected for contaminant analysis, from both offshore and inland lagoon locations, for approximately 150 analytes including: trace elements (e.g. heavy metals), PCBs, PAHs, selected pesticides (including DDT, chlordane and dieldrin), as well as energetic compounds associated with military activities. A total of 75 sites were analyzed for sediment contamination. Analyte concentrations at these sites can be compared to the nationwide NOAA National Status and Trends (NS&T) Program database, to determine the relative level of environmental contamination at these sites. In order to quantify the linkage between pollution and coral health, coral tissue samples (Porites astreoides) were also analyzed for contaminants from 35 sites. Overall, chemical contamination was fairly low, with the exceptions being elevated DDT (4 sites) and chromium (1 site), which exceeded published sediment quality guidelines, and while contaminants were detected in coral tissues, they were significantly lower than in sediments. Finally, the spatiotemporal variability of surface water nutrients were quantified; 40 sites (both offshore and in lagoons) were sampled a total of 8 times between May 2007 and March 2008. Nutrient concentrations were similar to what has been measured elsewhere in Puerto Rico, and were not well correlated with land use or precipitation. Field surveys were conducted at 75 sites to characterize benthic and fish communities on hardbottom around Vieques. Sites were stratified by former land use zones and the north/south coasts of Vieques. Hard coral cover was generally low, with a mean of 3.4 (±0.5)%. Several fish metrics varied on a north-south and/or east-west gradient, but there was often a high degree of variability within strata. Overall, differences in fish and benthic communities among strata could not be conclusively linked to former land-use patterns. In addition, updated and improved benthic habitat maps were created for Vieques. Relative to the latest comprehensive maps available, a smaller minimum mapping unit, more recent satellite and aerial imagery, and more detailed classification scheme were used. A total of 350 km2 of seafloor features around Vieques were classified by geographic zone, habitat structure, dominant cover, and live coral cover. The observed coral reef ecosystems were similar to what is seen elsewhere in Puerto Rico, and no spatial patterns related to current or historical land use were observed. |

Speaker(s): |
Jean-Luc Moncet (Atmospheric and Environmental Research) |
Abstract: |
Accurate modeling of atmospheric absorption and constraints on surface properties are needed to improve atmospheric retrievals and impact of assimilated satellite data on the weather forecasts. AER has developed line-by-line models (LBLRTM and MonoRTM) that have been used in many centers (including the JCSDA) as reference in the development of fast transmittance parameterizations as well as the Optimal Spectral Sampling (OSS) method for fast and numerically accurate parameterization of molecular absorption in the atmosphere. The line-by-line models are continuously validated and updated at AER. Recent updates have been made to the water vapor continuum in the microwave region and line mixing in the 4.3 micron CO2 band, and improvements have been made in the modeling of the 2400 cm-1 band head. The OSS model has been selected by EUMETSAT for the Meteosat Third Generation (MTG)- Infrared Sounding (IRS) Level 2 concept processor development and is among the candidate Fast Radiative Transfer Model’s for integration in the future MTG operational ground segment. The focus of current and future OSS development is on refining our generalized training capability. A status of the models will be discussed. A description of the work in progress on the use of our dynamically updated global atlas of microwave surface emissivities (sample hosted at the JCSDA) in the production of land surface temperatures under cloudy conditions will be provided. |

Abstract: |
""Bycatch" denotes the accidental mortality of seabirds from commercial
fishing activities. Thus, Alaskan commercial fisheries are concerned with
incidental mortality of endangered seabirds. A study comparing bycatch
reduction technologies was carried out in Alaska's Bering Sea. The three
technologies were: integrated weight longlines (IW), IW with paired
streamer lines (IWPS), and unweighted longlines with paired streamer lines
(UWPS). Generalized additive models (GAMs) were used to evaluate
treatment effects and other factors influencing catch rates. Seabird
bycatch rates were reduced by all mitigation methods; the relative
effectiveness varied by foraging guild. A management practice that adds
weighted lines to the paired streamer lines already in use can help
seabird conservation in longline fisheries, while not appreciably reducing
fish catch."

Hydropower Planning In Alaska: Does Climate Change Matter? |
Date/Time/Location/Seminar Sponsor: |
|
Speaker(s): |
Jessie Ellen Cherry (International Arctic Research Center & Institute of Northern Engineering, University of Alaska Fairbanks) |
Abstract: |
The supply, demand, and price for hydroelectric power can be strongly influenced by climatic factors such as temperature, precipitation, and water storage by the environment. The climate, in turn, is driven by both natural variability (on a variety of timescales) and anthropogenic forcing. For planning water resource management here in Alaska, particularly for long-lived, large infrastructure projects, it is useful to understand the sources of uncertainty in climate projections and how they influence long-term and short-term decision-making. A case study in Southeast Alaska is described, where most of Alaska’s hydropower facilities are concentrated. Challenges to assessing the regional impacts of climate change here are discussed, as well as our interpretation of the historical record of climate variability. Our analysis concludes that understanding and accounting for natural modes of variability may be as important as planning for long-term climate change when it comes to managing existing hydropower facilities and planning new infrastructure. |

|
Speaker(s): |
Kenneth G Foote (Applied Ocean Physics & Engineering; Woods Hole Oceanographic Institute) |
Speaker e-mail(s): |
kfoote@whoi.edu |
Abstract: |
Acoustic methodology for monitoring and surveying fish stocks is well established, but continues to evolve to address traditional applications better and to effect novel applications. The history of active-sonar methods is reviewed summarily, noting seminal developments in echo counting, echo integration, fish swimbladder resonance detection, Doppler and other behavioral measurement, echo statistics, sonar measurement, and calibration. Some of these are being pursued; others remain to be exploited. More recent developments are reviewed, including applications of multibeam, sidescan, and parametric sonars, as well as passive acoustic monitoring. Advances in acoustic methods are anticipated due to developments in transducer technology effecting greater bandwidth, and developments in platforms, especially underwater vehicles including gliders. Some efforts to address important issues of anthropogenic noise, such as that generated by research vessels and sonar use, with potential behavioral effects on marine life, are described. |

Self-similarity in the Classification of Drainage Networks and Effects of the Spatial Distribution of Imperviousness on Hydrologic Variability
|
Date/Time/Location/Seminar Sponsor: |
Wednesday, 10 March 2010, 11:00-12:00 ETZ [Check U.S. Time clock for your local time] (Seminar location: SSMC-2 (1325 East-West Highway, Silver Spring, MD, 20910), Room 8246; OneNOAA Science Seminar sponsored by: NOAA OHD) |
Speaker(s): |
Dr. Alfonso Mejia (NRC Research Associate in OHD) |
Abstract: |
This seminar will cover two separate topics. The first topic entitled “Self-similarity in the Classification of Drainage Networks” shows how basin planform self-similarity, and deviations from it, can be used to develop a classification system for drainage network patterns. In the past, drainage patterns have been identified and classified by researchers, first by visual inspection of maps and areal photos and more recently by automatic methods. The main drawback of existing automatic methods is that they require a large number of seemingly unrelated stream network characteristics to identify a distinct pattern. Thus the main goal with this research was to develop a simpler classification based on measures derived from planform self-similarity. Results from the proposed classification show that planform self-similarity is able to reduce the classification problem to fewer basin characteristics and provide a unified framework. The second topic is entitled “Effects of the spatial distribution of imperviousness on hydrologic variability”. This research shows that the way imperviousness, or urbanization, is distributed on the landscape can have an influential effect on hydrologic variability. Typically, the effects of urbanization are accounted for in time and the spatial pattern is not considered or only accounted for at the hillslope scale. Additionally, policy recommendations on the urban form are being made based on benefits to water resources that are largely qualitative. Thus the main goal of this research was to better understand the role of the imperviousness pattern at the basin scale and provide a quantitative framework to facilitate its interpretation. To study the role of imperviousness three different approaches were taken. The first approach interprets the effects of the spatial distribution of imperviousness as an optimization problem. From this approach, peak flows were found to decrease globally (along the entire stream network) when imperviousness is clustered along the main stream. The second approach examines the effects of the optimized patterns on hydrologic response using an event-based model. The third approach develops a synthesis framework that accounts analytically and explicitly for the imperviousness pattern and the space-time variability of rainfall, runoff generation, and hydrologic response. From this last approach, average rainfall excess was found to depend on the interaction between the space-time rainfall and the imperviousness pattern, and peakedness was found to vary across scales. Overall results are supportive of the need to account in the future for the space-time evolution of imperviousness in urbanized basins. |

Abstract: |
NOAA's Mission is driven by Science, Service, and Stewardship. Each of these drivers includes significant international aspects. We work collaboratively with other nations to make measurements and observations and share that data to develop, test, and evaluate our models. Our science and understanding are enriched through interactions with international peers. Besides providing information services to decision and policy makers domestically, NOAA also shares these services and others not only with our neighbors, but globally as well. Stewardship involves both conserving and preserving our domestic resources and protecting those resources from external threats. In the broader picture, stewardship extends to protecting resources in the world-wide ecosystem since national borders are not barriers to phenomena in the oceans and atmosphere. The relationship between the Office of International Affairs, the Line Offices, Goal Teams, and International Affairs Council will be described. What will be presented includes examples of international activities which significantly support NOAA's Mission and opportunities for enhancing international contributions. |

Abstract: |
Douglas Burnett will talk on key components of the international legal rights and obligations related to submarines cables. Included in the presentation will be current developments with regard to cable security and environmental issues, including marine mammals and activities between industry and the UN Environmental Programme and other areas where NOAA has important roles.
Submarine cables have been used in the oceans since 1850 but never have their importance been so pronounced as now. International fiber optic submarine cables carry over 95 percent of the international internet communications of the United States, including voice, data, and video communications. About 35 cables, each with a diameter of a garden hose, link the United States with the world and are critical national infrastructure by any metric. The use of cables for scientific observations and military purposes is also expanding rapidly. Cables are comprehensively treated in the United Nations Law of the Sea Convention (UNCLOS) which supplies the legal framework under which they are laid and maintained. The attached chart highlights the applicable provisions of UNCLOS, the Geneva Conventions on the High Seas and Continental Shelf, and the 1884 International Convention for the Protection of Submarine Cables. |

A Comparison Study of Calibration Strategies for the NWS Research Distributed Hydrological Model (HL-RDHM)

Speaker(s): |
JJ Gourley (NSSL) and Humberto Vergara (PhD student at the U. of Oklahoma in Norman) |
Abstract: |
This study evaluates the performance of the NWS Research Distributed Hydrologic Model (HL-RDHM) subject to five different parameterizations. The model parameters were estimated during the calibration period using the traditional manual approach, two local optimization searches, and two sophisticated global optimization methods. While being relatively costly in terms of computational resources and time, the global optimization method (with some added constraints) achieved the greatest accuracy in simulating streamflow during calibration. The overall best performance during the validation period, however, was accomplished with the model that was calibrated with the step-wise, local optimization method. Further analyses of the results during validation indicated the models calibrated manually and with the global optimization methods offered improvements over the local optimization search during high flow periods (i.e., flow exceedance probability < 10%). This study provides information about the performance of a high-dimensional, rainfall-runoff model based on different calibration strategies with a consideration of the desired objectives (i.e., accuracy during calibration, validation, high flows, low flows) and required computational resources. Particular emphasis was placed on model performance during high flow events, in conjunction with the modeling objectives of the Coastal and Inland Flooding Observation and Warning (CI-FLOW) project. |

Accounting for pinniped predation in fisheries stock assessment:
implications for the recovery of B.C. inside waters yelloweye rockfish

Speaker e-mail(s): |
m.mcallister@fisheries.ubc.ca |
Abstract: |
Many B.C. rockfish populations have undergone pronounced declines in the last several decades largely due to episodic high fishing mortality rates. In contrast, B.C. pinniped populations have shown marked increases since the implementation of Canadian Marine Mammal Protection Laws in the early 1970s. Strait of Georgia harbour seals (Phoca vitulina richardsi), for example, have increased from about 3,500 animals in the 1970s to currently about 42,000 animals. Diet studies indicate that rockfishes form only a small fraction of the diet of B.C. pinnipeds. However, the high annual total rates of consumption per animal and current high abundance of pinnipeds in B.C. waters suggest that predation rates on B.C. rockfishes may have increased substantially over the last few decades. In this talk, I present adaptations of a stock assessment model for B.C. inside waters yelloweye rockfish (Sebastes ruberrimus) that accounts for variations in predation since the early 1900s and assesses the implications of current trends in pinniped abundance for rockfish population recovery.

On Some Useful Connections Between Hydraulic Routing and Rainfall-Runoff Modeling
|

Thursday, 11 March 2010, 11:00-12:00 ETZ [Check U.S. Time clock for your local time] (Seminar location: SSMC-2 (1325 East-West Highway, Silver Spring, MD, 20910), Room 8246; OneNOAA Science Seminar sponsored by: NOAA OHD) |
Speaker(s): |
Dr. Alfonso Mejia (NRC Research Associate in OHD) |
Abstract: |
This seminar will cover research aimed at determining and recommending ways in which predictions (simulated flows at the outlet of headwater basins) may be improved through the combination of hydraulic routing and rainfall-runoff modeling. The work completed thus far is separated into three research areas. The first research area develops a diffusion wave strategy for routing flows within HL-RDHM. The goal of this research was to assess the feasibility of diffusion routing within the current HL-RDHM model structure. From this research, it was found that the two parameters in the diffusion wave (wave celerity and the dispersion coefficient) can be related to the existing a-priori routing parameters (local channel slope, roughness coefficient, and two cross section shape parameters) used in HL-RDHM. Additionally, a numerical strategy for implementing diffusion wave routing was identified from the literature. The numerical strategy remains to be tested within HL-RDHM. It seems beneficial to test this strategy on a stream reach, prior to implementation on a stream network, to determine the stability and accuracy of the numerical solution. The second research area was to replace a portion of the HL-RDHM main stream reach in the Blue and Illinois River basins with a HEC-RAS model. The goal with this research was to assess coupling of the two models, examine the role of parameterized cross section shapes, and assess advantages/disadvantages from implementing a more general routing method. It was found that the external coupling approach is quite inefficient and limiting. It requires a substantial amount of effort and time to set up and transfer information to the hydraulic model, making a systematic analysis of parameters and uncertainty unrealistic. It was also found that some benefit may be possible from including floodplain hydraulic geometry in the routing process. The magnitude of this benefit needs to be identified more precisely with a more efficient modeling framework. The last research project looked at how existing analytical routing criteria may provide information regarding the basin scale where a given routing method (kinematic, non-inertia, or dynamic wave routing) becomes dominant. The goal with this research was to provide additional support to the selection of a routing method. For this research, an existing criteria was chosen and combined with the basin geomorphology, climate, and hydrologic response. The latter is used to extend the criteria to account for basin size. Preliminary numerical tests suggest a strong dependence of the criteria to the slope-area relationship, indicating that this might be a useful quantity when trying to choose a routing method. The combined criteria also shows a tendency for diffusion to become more dominant with increasing basin size. Based on the performed research, a next step could be to continue with the implementation of the diffusion wave strategy and examine the possibility of including floodplain hydraulic geometry. |

Abstract: |
Coastal Louisiana and Texas are characterized by tremendous complexity and variability in their geography, topography, bathymetry, continental shelf, estuarine systems, and surface roughness. Hurricane Ike significantly impacted both coastal Texas and Louisiana producing a storm surge of more than 5.3m in eastern Texas and more than 2.2 m in eastern Louisiana (more than 500 km away from the storm landfall location). Particularly important was that more than 2m of hurricane forerunner developed prior to the storm coming onto the continental shelf (more than 15 hours prior to landfall), while coastal winds were shore parallel or coming off of the land. The forerunner flooded much of western Louisiana and eastern Texas, and filled Galveston Bay in its entirety, reaching into the heart of Houston. The forerunner then propagated down the Louisiana-Texas (LATEX) shelf as a free wave, passing Corpus Christi with an amplitude of more than 1m. The forerunner is the largest ever recorded. The rapid evolution of data collection systems allows the physical system to be accurately defined, and the rapid evolution of unstructured grid computational models allows these characteristics and the resulting waves and flows to be numerically resolved. The SWAN+ADCIRC unstructured grid modeling system has been developed to simulate fully coupled hurricane winds, wind-waves, storm surge, tides and river flow in this complex region. This is accomplished by defining a domain and computational resolution appropriate for the relevant processes, specifying realistic boundary conditions, and implementing accurate, robust, and highly parallel unstructured grid algorithms for both the wind waves and the long wave current/storm surge/tide model. Basin to channel scale domains and high resolution grids which resolve features down to 30 meters and contain up to 3.3 million nodes have been developed. This modeling system is run on up to 4,096 processors and requires as little as 18 minutes of wall clock time per day of simulation. Hindcasts of the storm indicate an excellent match of measured wave and surge records. Numerical experiments indicate that the unprecedented forerunner was generated by very fast shore parallel currents driven by the early shore parallel winds that allow for a Coriolis driven set up to be pushed up against the coast. Achieving fast enough currents on the mid and outer shelf is vital for the driving mechanism to work. This in turn requires low frictional resistance which is consistent with the smooth and muddy LATEX shelf. |

About the speaker(s): |
Joannes Westerink is Professor of Civil Engineering and Geological Sciences at the University of Notre Dame. He has a concurrent appointment in the Department of Mathematics. He obtained his B.S. and M.S. degrees in Civil Engineering at the State University of New York at Buffalo and Ph.D. degree in Civil Engineering from the Massachusetts Institute of Technology. Westerink’s research focuses on the development, analysis and application of coastal ocean and estuarine hydrodynamic, constituent transport and sediment transport models. This encompasses the basic algorithms; the behavior of these algorithms for varying levels of time and spatial discretization as well as varying hydrodynamics balances; theoretical analysis of algorithms to understand baseline properties; development of high performance codes in vector and parallel computing environments; application of codes to oceans, continental shelf regions, estuaries, rivers, coastal flood plains and lakes; and the linkages of hydrodynamics models to weather and short wind wave models. He has worked extensively on model validation and applications in the Gulf of Mexico, Louisiana, and Texas. Westerink has been the developer or co-developer of numerous coastal hydrodynamic and transport models. He developed a frequency domain – time domain finite element based shallow water equation model, TEA (Tidal Embayment Analysis). The TEA model was notably used in the design and analysis work to place sewage outfalls in the Boston Harbor cleanup. Westerink and Rick Luettich of the University of North Carolina at Chapel Hill have been the co-developers of the ADCIRC finite element based shallow water equation model. ADCIRC is a very stable and effective solution method due to its ability to handle unstructured grids placed in large computational domains to provide grid resolution where it is necessary and to simplify boundary condition specification. The model is applied to compute basin scale phenomena to inlet scale flows to feature scale flows such as flow around a jetty. The U.S. Army and Navy extensively use the ADCIRC model worldwide to assess coastal currents and flooding. The National Oceanic and Atmospheric Administration (NOAA) makes extensive use of the ADCIRC coastal ocean model in support modeling tidal harmonic constituents for U.S. coasts and estuaries. Second, NOAA is utilizing ADCIRC to further its capabilities to study and predict coastal inundation processes. ADCIRC is being used to support development of the nation's next generation storm surge prediction system, and to understand the impacts of sea level rise at the coast. ADCIRC is also being used to design flood protection systems in Southern Louisiana by the Army Corps of Engineers and to evaluate flooding risk across the U.S. east and Gulf coasts by FEMA. Westerink was a team co-lead in the Army’s IPET investigation of the Katrina flooding failures in Louisiana and continues to work extensively in the evaluation of flood mitigation systems in Louisiana and Texas. Westerink’s current research includes algorithmic and peta-application projects (one of 14 groups in the U.S. selected to build software for the nation’s planned peta-scale computers) from the National Science Foundation, the merging of SWAN+ADCIRC into a high performance code for the Office of Naval Research in a joint project with Delft University, the development and validation of the SL16 model for Southern Louisiana and a new model for Texas with the U.S. Army Corps of Engineers and numerous university and private sector partners, and marsh resistance and wave-current friction studies with ERDC. His former graduate students and post docs in academia, government, and industry work extensively on hurricane studies. |

Abstract: |
Theoretical rapid intensification (RI) mechanisms are diagnosed for high-resolution, 1.33 km Advanced Hurricane WRF (AHW) simulations of three Atlantic hurricanes known to have historically undergone rapid strengthening: Katrina (2005), Gordon (2006) and Felix (2007). A simulated 27 h period detailing the times of RI for each tropical cyclone was evaluated against the NHC Best Track dataset. The verified model output was put into the context of key features thought to be associated with RI. Following the arguments of Black et al. (2002) and Braun et al. (2006), these features are discussed for each hurricane. Five subsequent fields are analyzed: low-level winds, 850 hPa positive vorticity, precipitable water, 0-6 km storm-relative helicity and most-unstable convective available potential energy. The fields piece together a comprehensive model that diagnoses the effect moderate to strong shear has on numerically simulated RI by linking convective and rotational features within the eyewall. Conclusions are drawn on the how well the AHW resolves overall intensity change and the ensuing inner core dynamics. Forecasting potential of this evaluation method is discussed. |

Abstract: |
The Global Observing Systems Information Center ( GOSIC), initiated in 1997 at the request of the Global Climate Observing System (GCOS) Steering Committee (see http://www.wmo.int/pages/prog/gcos/Publications/gcos-39.pdf), responds to a need identified by the global climate observing community for easier and more effective access to observational climate data and information. GOSIC manages an online portal providing an entry point for users of climate-related global observing systems data and information systems. Following its initial development and implementation at the University of Delaware from 1997 to 2006, the U.S. National Oceanic and Atmospheric Administration's National Climatic Data Center (NCDC) assumed operational responsibility for GOSIC on behalf of the international climate observing and data user communities. The goal of GOSIC is to provide basic user services, including a description of the systems and their data as well as a tailored search capability that facilitates access to a worldwide set of observations and derived products. GOSIC's unique value is its ability to quickly link users, via a consistent and user-friendly interface, to a wide range of data sets that reside at multiple data centers; the GOSIC portal ( http://GOSIC.org) provides users with links to data, metadata, other search tools, and related climate-observing information. |

John Schaake (NWS/OHD) and Dan Sheer (Hydrologics) |
Abstract: |
The New York City (NYC) water supply system is operated by the NYC Department of Environmental Protection (DEP) to provide water to more than 9 million people. To help manage this complex system with many reservoirs and several large aqueducts, NYCDEP contracted with the engineering firms of Hazen and Sawyer (NYC) and Hydrologics (Columbia, MD) to develop a decision support system that was initially used in a planning mode to simulate operation of the NYC reservoirs, including daily release and diversion decisions, within the context of water quality objectives, water supply reliability objectives, and release requirements throughout the system.
The next phase of work is to integrate this decision support system into an Operations Support Tool (OST) that will use NWS ensemble weather, water and climate forecasts as inputs to support model simulations in Position Analysis (PA) mode. The OST will link DEP’s water quality and quantity models; assimilate near-real-time data on reservoir levels, stream flow into the reservoirs, snowpack and water quality in streams and reservoirs; and ingest NWS forecasts. At the same time, it will apply the rules and laws that govern the water supply operations. And it will involve close collaboration between the NYCDEP and the NWS. This seminar will describe the NYC water supply system, the OST and NWS ensemble forecast requirements. |

Decoupling of The Temperature-Nutrient Relationship in the California Current Ecosystem with Global Warming
|
Date/Time/Location/Seminar Sponsor: |
Tuesday, 16 March 2010; 12:00-13:00 ETZ [Check U.S. Time clock for your local time] (Seminar location: SSMC-3 (1315 East-West Highway, Silver Spring, MD, 20910), 2nd Floor; OneNOAA Science Seminar sponsored by: NODC NOAA Central Library) |
Speaker(s): |
Dr. Ryan R. Rykaczewski and Dr. John P. Dunne (NOAA Geophysical Fluid Dynamics Laboratory) |
Abstract: |
In the California Current Ecosystem (CCE), an inverse relationship between temperature and nitrate is evident over the observational period at interannual to decadal time scales. This robust relationship has encouraged use of temperature as a proxy for nutrient content and allowed extension of nutrient time series backwards in time over multiple decades. Understanding of this relationship has also been extrapolated to suggest that nutrient supply to the euphotic zone of the CCE will be inhibited in the future as the pycnocline strengthens with global warming, and primary and secondary production are expected to decrease in response to decreased nutrient supply. Here, we explore the effect of global warming on the production and nutrient supply of the CCE using a basic biogeochemistry model (TOPAZ) coupled to an ocean-atmosphere general circulation model (GFDL CM 2.1). We find that nutrient supply to the euphotic zone and primary production in the CCE increase as surface ocean temperatures rise. The mechanism relating physical factors to production at multi-decadal to centennial periods differs from that at shorter time scales, and the interannual and multidecadal relationship between nitrate and temperature should not be extrapolated to predict the response of the CCE to global warming. Although contrary to the traditional understanding of interannual and decadal variability in the CCE, this result is consistent with trends in the longest observations of chlorophyll content, nutrient content, and water clarity (as a proxy for chlorophyll content) which show that production has increased over the past 30 to 40 years despite an increase in surface temperatures. We find that the increase in nutrients in the euphotic zone of the CCE is the result of changes in the nutrient content and ventilation of the deep source waters to the region rather than a change in the rate of upwelling, mixed layer depth, or horizontal advection in the surface layers. This change is a consequence of increased stratification and weaker atmospheric circulation over the subtropical gyre. In addition to the long-term increase in primary production, increased temporal and spatial variability in production are predicted in the CCE. Further consideration of the ramifications of such changes to fisheries is warranted. |

Abstract: |
Southeast US has historically enjoyed abundant water resources, but recent decades ushered in rapid
population increase, crawling urbanization, unsustainable agricultural expansion, severe droughts
with devastating socioeconomic consequences, widespread river pollution, endangered ecosystems,
and litigious transboundary water disputes. These challenges are exemplified in the Apalachicola-
Chattahoochee-Flint (ACF) River Basin shared by Alabama, Georgia, and Florida, which provides a
wealth of regional water resources, energy, environmental, ecological, and socio-economic benefits.
The study includes (1) processing all IPCC available GCM scenarios for bias correction and
downscaling, (2) developing physically based models for all ACF sub-watersheds, and (3)
incorporating the watershed response within an adaptive river and reservoir regulation and assessment
model encompassing all ACF storage facilities and water uses.
An assessment of the historical 1901-2009 period shows that the ACF exhibits drier soil moisture and
runoff trends, with drought impacts exacerbated by inflexible federal project regulation practices and
ineffective drought management plans. Basin assessments with future climate and demand scenarios
indicate that (1) drier trends will continue with drought and flood episodes becoming more severe,
and (2) lake levels, water supply reliability, energy generation, and ecological flows are impacted
adversely. The study illustrates that there is a critical need for flexible technical and institutional
measures to mitigate and adapt to simultaneous climate, demand, and land use change. Adaptive
management was shown to be a particularly effective mitigation strategy.

Ocean Acidification
in Alaska |
Date/Time/Location/Seminar Sponsor: |
|
Speaker(s): |
Dr. Jeremy Mathis (School of
Fisheries and Ocean Sciences, University of Alaska Fairbanks) |
Abstract: |
Since the Industrial Revolution approximately 1/3 of all human CO2 emissions have been absorbed by the ocean. While this process has mitigated global temperature increases it has had a profound effect on the chemistry of the surface ocean, making the water more acidic. This phenomenon is exacerbated in the cold, highly productive waters in the continental shelf seas surrounding Alaska. Recent observations have shown that the bottom waters over the shelves of the Chukchi and Bering Seas, as well has the Gulf of Alaska become undersaturated with respect to aragonite in late summer and fall. These undersaturated waters could be corrosive to shell building organisms such as clams, oysters, and crabs. Here, the controls and seasonal distribution of ocean acidification around Alaska will be discussed in the context of the import commercial fisheries. |

Abstract: |
In this presentation, an overview of international developments in high seas conservation will be provided. Examples of ongoing scientific research / analyses relevant in applying various internationally-accepted conservation planning criteria will be provided, as well as opportunities and challenges ahead.
Working in the high seas, it is impossible not to be faced with issues surrounding incomplete data / knowledge, and how we can make decisions in such situations. Of course, to various extents, incomplete knowledge of ecosystems plagues the daily lives of marine conservation scientists, practitioners and decision-makers everywhere, and there is little sign that this will change soon... So, how do we balance the need to know with the need to act? Addressing ever-mounting environmental problems requires moving beyond habitually calling for more sectoral research, laudable though that may be, to learning how to deal collaboratively with what little we’ve got. In this part of the presentation, I would like to put forward some preliminary ideas developing as part of a collaborative research effort with James Cook University (Australia) on “adaptive Maritime Spatial Planning” (aMSP). |

Abstract: |
NOAA Restoration Day is an annual opportunity for NOAA employees to put into action the mission they support in their office work while helping to restore and protect the Chesapeake Bay. This is one of the largest voluntary federal employee-sponsored environmental stewardship events in the Chesapeake Bay watershed and for the past seven years, NOAA volunteers have had a great time growing underwater grasses in our Silver Spring offices and planting them in the Chesapeake Bay. This year we will be trying something new – growing and planting switchgrass! Switchgrass, or beachgrass, is typically found on beach dunes and helps stabilize the shoreline. We have 22 grow tanks to be distributed NOAA-wide. It’s easy to set-up a tank in your office and only takes a small time commitment. After 2.5 months, your grasses will be planted as one of several, get your hands dirty and get out in-the-field, NOAA Restoration Day activities in June being held at the NOAA Oxford Lab, one of five research labs for the NOS National Centers for Coastal Ocean Science (NCCOS) located in Oxford, MD ( http://www.chbr.noaa.gov/oxfordlab/default.aspx).
All are welcome to attend the workshop to learn more about Chesapeake Bay habitat, growing switchgrass in your office, and to receive your tank supplies. Due to limited supplies, if your office is interested in hosting a tank you must RSVP by March 19 and seek prior approval from your Office Director. Tanks are available on a first come, first served basis.

Abstract: |
Soil moisture plays a vital role in the partitioning of sensible and latent heat fluxes in the surface energy budget
and the lack of a dense spatial and temporal network of ground-based observations provides a challenge to the
initialization of the “true” soil moisture state in numerical weather prediction simulations. The retrieval of soil
moisture using observations from both satellite-based thermal-infrared (TIR) and passive microwave (PM)
sensors has been developed (Anderson et al., 2007; Hain et al., 2009; Jackson, 1993; Njoku et al., 2003). The
ability of the TIR and microwave observations to diagnose soil moisture conditions within different layers of the
soil profile provides an opportunity to use each in a synergistic data assimilation approach towards the goal of
diagnosing the “true” soil moisture state from surface to root-zone. TIR and PM retrievals of soil moisture are compared to soil moisture estimates provided by a retrospective Land Information System (LIS) simulation using
the NOAH LSM during the time period of 2003 - 2008. The TIR-based soil moisture product is provided by a
retrieval of soil moisture associated with surface flux estimates from the Atmosphere-Land-Exchange-Inversion
(ALEXI) model (Anderson et al., 1997; Mecikalski et al., 1999; Hain et al., 2009). The PM soil moisture retrieval is
provided by the Vrijie Universiteit Amsterdam(VUA)-NASA surface soil moisture product. The VUA retrieval is
based on the findings of Owe et al. (2001; 2008) using the Land Surface Parameter model (LPRM), which uses
one dual polarized channel (6.925 or 10.65 GHz) for a dual-retrieval of surface soil moisture and vegetation
water content. In addition, retrievals of ALEXI (TIR) and AMSR-E (PM) soil moisture are assimilated with the LIS
and the NOAH LSM. A series of data assimilation experiments are completed with the following configuration,
(a) no assimilation, (b) only ALEXI soil moisture, (c) only AMSR-E soil moisture, and (d) ALEXI and AMSR-E soil
moisture. The relative skill of each assimilation configuration is quantified through a data-denial experimental
design, where the LSM is forced with an inferior precipitation dataset (in this case, the TRMM 3B42RT
precipitation dataset). The ability of each assimilation configuration to correct for precipitation errors is
quantified through the comparison of the results with a single simulation over the same domain with a highquality
(NLDAS) precipitation dataset. Finally, applications of ALEXI surface flux estimates with respect to the
detection and monitoring of drought across North America will also be presented. |

The Kittlitz’s Murrelet: Alaska's Next Polar Bear or a Total Misunderstanding?
|
Date/Time/Location/Seminar Sponsor: |
Tuesday, 30 March 2010; 12:00-13:00 ETZ [Check U.S. Time clock for your local time] (Seminar location: SSMC-3 (1315 East-West Highway, Silver Spring, MD, 20910), 2nd Floor; OneNOAA Science Seminar sponsored by: NODC NOAA Central Library) |
Speaker(s): |
Scott Gende (National Park Service, Glacier Bay Field Station, Juneau, Alaska ) |
Abstract: |
The Kittlitz’s murrelet (KIMU) is one of the rarest seabirds in North America, found only in Alaska and the Russian Far East. Historical population estimates are highly variable due in part to difficulties in monitoring this species: typical counts at nesting colonies do not work for this species because they are solitary nesters. What’s more KIMU are small and roost on the water which has resulted in imprecise or biased at-sea abundance estimates. Nevertheless, best estimates suggest a range-wide population decline of up to 84% over the past several decades provoking the USFWS to upgrade the species to a Candidate 2 listing priority under the Endangered Species Act. They are also considered “critically endangered” (IUCN Red List 2006). Because KIMU are closely associated with glacial habitats there is speculation that global climate change and loss of glacial habitat may be linked to population declines. However, because so little is known about this species, causal factors associated with the declines are highly speculative.
For the past five years we have been studying Kittlitz’s murrelets in and adjacent to Wrangell-St. Elias National Park, southeastern Alaska. This area, combined with Glacier Bay National Park supports upwards of 15-20% of the global population of this species, with Icy Bay, adjacent to Wrangell-St.Elias, supporting the highest density of KIMU found in the world. Each of these areas is characterized by large glacial habitats, tidewater glaciers, and early successional landscapes. At the onset of this project less than 25 nests of this species had ever been found, with only a subset of those scientifically investigated. Less than 20 individuals had been captured and radio-tagged with very little known with regards to even their most basic life-history (movements, habitat use, nesting ecology, population structure, etc). Not surprisingly the Birds of North America consider the Kittlitz’s murrelet one of the least know species that breeds in North America.
We have since captured over 300 Kittlitz’s murrelets and radio tagged and tracked over 100 individuals from 205-2009. Eight nests have been found, some as far as 4500’ in elevation over hanging glaciers; all have been in early successional habitats. Nesting attempts and success in this area appears to be very low, despite very little direct anthropogenic impacts. At several nests we placed cameras capturing footage of behavior rarely, if ever, recorded for this species. Perhaps more importantly, adult survival during the breeding season may be strongly influenced by predation rates from several raptor species. The uncertainty in factors driving abundance, their implications for management, and possible mechanisms by which climate change may (or may not) be a major driver in population dynamics will be discussed. |

Mr. Daniel Neumann (NOAA Office of Coast Survey) |
Abstract: |
NOAA and its predecessor agencies have completed over 16,300 hydrographic surveys, dating back to 1837. Digital metadata capture from these surveys began in 1997 with the inception of the hydrographic survey descriptive report preservation project. Metadata recovered from the hydrographic survey descriptive reports was entered into a database implemented in DB3, and subsequently migrated to Microsoft Access. Metadata was gradually expanded to reflect the how, where and why of each survey. Migration to a new Oracle platform was achieved in 2004, through a partnership with the National Geophysical Data Center (NGDC). Since 2004, hydrographic survey metadata presentation and query has increased in sophistication to the present day offerings on the NGDC Map Service Web Browser. The newest metadata product is the Hydrographic Survey Rap Sheet, a user-friendly summary metadata view which came on line in late January of 2010 and is now available for surveys from 1982 to the present. This seminar illustrates how to access NOAA’s hydrographic survey metadata and data through the NGDC site. |

Abstract: |
Malaria is the major vector-born disease in the world. It occurs in 107 countries with a ½ of world population. Every year 300-500 million clinical cases of malaria occur with 1.5-3
million fatalities. Children, old people and pregnant women are the most vulnerable to
malaria. Africa is the most affected continent, which contributes 60 % of global malaria
cases and 80% of death. Malaria is strongly affected by the environment. Climate and
ecosystems determines distribution of malaria and weather affects timing, duration,
area and intensity of outbreaks. In general warm and wet weather stimulated
mosquitoes hatching, activity and the rate of malaria transmission to people. Satellite
data have been used in recent years to monitor malaria based on Vegetation Health
(VH), method that have been developed applied successfully for early detect and
monitor malaria from the operational environmental satellite. The VH was developed
from reflectance/emission measured by the Advanced Very High Resolution Radiometer
(AVHRR) flown on NOAA polar-orbiting satellites since 1981. The calibrated
measurements were converted to the Normalized Difference Vegetation Index (NDVI)
and brightness temperature (BT), which were expressed as a deviation from 30-year
climatology. Three indices characterizing moisture (VCI), thermal (TCI) and vegetation
health (VHI) conditions were produced and calibrated against in situ data. They were
applied to identify malaria early enough to mitigate its consequences. These results
covering several countries in Africa, Asia and South America will be presented. |

Cardiovascular Risks and Benefits of Fish Consumption-Qualitative and Quantitative Risk-Benefit Assessment |

Abstract: |
Controversy has arisen among the public and in the media regarding the health effects of fish intake in adults. Substantial evidence indicates that fish consumption reduces coronary heart disease mortality, the leading cause of death in developed and most developing nations. Conversely, concerns have grown regarding potential effects of exposure to mercury and other contaminants found in some fish. Because fish consumption appears to have important health benefits in adults, elucidating the relationships between fish intake, mercury and other contaminant exposure, and health risk is of considerable scientific and public health relevance. Modest consumption of fish (e.g., 1-2 servings/wk), especially species higher in the n-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), reduces risk of coronary death by 36% (95% confidence interval, 20%-50%; P<.001) and may favorably affect other clinical outcomes. Women of childbearing age and nursing mothers should consume seafood for optimal brain development in their children, limiting intake of only a few selected species. Health effects of low-level methylmercury in adults are not clearly established; methylmercury may modestly decrease the cardiovascular benefits of fish intake. A variety of seafood should be consumed; individuals with very high consumption (≥ 5 servings/wk) may wish to limit intake of species highest in mercury levels. Levels of dioxins and polychlorinated biphenyls in fish are low, and potential carcinogenic and other effects are greatly outweighed by potential benefits of fish intake and should have little impact on individual choices for commercial seafood consumption. (All individuals should consult regional advisories for local sportscaught fish). For major health outcomes among adults, based on both the strength of the evidence and the potential magnitudes of effect, the benefits of fish intake greatly exceed the potential risks. These findings demonstrate that quantitative and comparable assessment of risks and benefits is needed to make informed recommendations about optimal fish consumption. Such evaluation has been limited in the past by widely varying standard methods for assessing nutritional benefits vs. toxicological risks.

Abstract: |
The next generation Geostationary Operational Environmental Satellite (GOES-R) series with a planned launch in 2015 includes an advanced imager and a new capability for total lightning detection (cloud and cloud-to-ground flashes). The Geostationary Lightning Mapper (GLM) will map total lightning activity continuously day and night with near-uniform spatial resolution of 8 km and with a product refresh rate of less than 20 sec over the western hemisphere from the west coast of Africa (GOES-E) to New Zealand (GOES-W) when the constellation is fully operational. Near global coverage will be possible by the end of the decade with operational lightning imagers planned by EUMETSAT and the Chinese Meteorological Agency. Cloud-resolving numerical models, such as the Weather Research and Forecasting (WRF) model, now have the capability of computing fields of mixing ratios of multiple species of hydrometeors, including several important ice-phase species known to be associated with lightning flash rate (graupel, hail, ice water content). In this presentation, we review the past decade of data assimilation experiments using proxy relationships for lightning and present new methodologies and opportunities to demonstrate how regional cloud-resolving forecast simulations can be exploited to create quantitatively calibrated, time-dependent and specific short-term forecasts of lightning flash rates in convective environments. Our prototype methods being tested at the NOAA Hazardous Weather Testbed and Storm Prediction Center this spring yield lightning forecast products that are straightforward, while avoiding the added expense and complexity of incorporating explicit cloud electrification algorithms into the models. |

Abstract: |
A series of airborne hyperspectral remote sensing campaigns were conducted from 2002 to 2005 at five U.S. estuaries: Apalachicola Bay, FL; ACE basin, SC; Grand Bay, MS; Delaware Bay, DE; and Chesapeake Bay, MD. 151 field stations were occupied within the flight tracts where the following were obtained: (1) water reflectance R(λ) spectra were acquired by a pair of ocean optic 2000 spectroradiometers, simultaneously, the concentration of (2) chlorophyll a and (3) total suspended solid, and the (4) absorption of colored dissolved organic matter (CDOM) were measured at these stations. A principal component analysis was conducted to characterize the general variability of these water reflectance R(λ) spectra, and explore the factors that drive the variability of water reflectance in optically complex coastal environments. The results suggested that water reflectance spectra in turbid estuarine waters are the results of complex interactions of phytoplankton pigments, total suspended solids, and CDOM. The first principal component, which represents 72% of total variance of R(?), is strongly affected by scattering of total suspended solids and the absorption of CDOM at the green region of spectra; while the second principal component represents 20% of total variation of R(λ) spectra is mainly driven by phytoplankton biomass e.g. Chl a concentrations in red and near infrared spectral regions. Furthermore, the results of this study could provide a framework for using hyperspectral remote sensing as a cost effective method to characterize water quality in optically complex coastal waters. |

Demography and Genetic Structure of a Recovering Grizzly Bear Population

Abstract: |
The threatened grizzly bear (Ursus arctos) population in northwestern Montana has been managed for recovery since 1975, yet no rigorous data were available to monitor program success. We used data from a large noninvasive genetic sampling effort conducted in 2004 and 33 years of physical captures to assess the abundance, distribution, and genetic structure of this population. We combined data from 3 sampling methods (hair trap, bear rub, and physical capture) to construct individual bear encounter histories for use in Huggins–Pledger closed mark–recapture models. Our population estimate, = 765 (CV = 3.8%) was more than double the existing estimate derived from sightings of females with young. Based on our results, the estimated known, human–caused mortality rate in 2004 was a 4.6% (95% CI: 4.2–4.9%), slightly above the 4% considered sustainable; however, the high proportion of female mortalities raises concern. Using location data from genetic sampling, telemetry, and confirmed sightings, we found that grizzly bears occupied 33,480 km2 in the NCDE during 1994–2007, including 10,340 km2 outside the recovery zone. We used factorial correspondence analysis to identify potential barriers to gene flow within this population. Our results suggested that genetic interchange recently increased in areas with low gene flow; however, we also detected evidence of incipient fragmentation across the major transportation corridor in this ecosystem. Our results suggest that the NCDE population is faring better than previously thought, and highlight the need for a more rigorous monitoring program than the Grizzly Bear Recovery Plan specifies.

The Role of Tourism in Fisheries Crises: The Case of Newfoundland and Applications to Maine

Speaker(s): |
Natalie Springuel (Sea Grant, Maine) |
Abstract: |
Tourism is increasingly touted as a development opportunity for coastal and rural areas affected by natural resource decline. As commercial fisheries face depletion the world over, people look to tourism to help coastal communities recover from economic crisis, but little work has been done to explore if the investment in tourism can ever replace the full human ecological value of the fishery, including its impacts on a region's culture, economy, and environment. Springuel's sabbatical in Newfoundland examined the impact of the 1992 cod moratorium on Newfoundland's coastal communities over the last 16 years, and particularly how marine heritage tourism has emerged as a model in the province's revitalization attempts. Dozens of interviews with Newfoundlanders involved in tourism and fisheries (including current and former fisherman and fish plant workers, boat captains, tour operators, community development and government representatives, residents, community leaders, academics, and front line staff at tourism destinations, visitor centers and museums) and first hand observations of marine tourism destinations show that marine heritage, in particular, has contributed to both the revitalization of devastated outports and the rise of tourism in these coastal communities. Though tourism will never replace an exhausted natural resource, it can play an important role in the future of coastal and rural areas. Maine's reliance on a single marine fishery (lobster) mirrors Newfoundland's reliance on cod. This presentation will highlight the Newfoundland experience and touch on how lessons learned can be applied in Maine. |

Abstract: |
Food simulations for engineering studies and operational forecasting are traditionally carried out using one-dimensional (1D) numerical models, which present serious limitations for simulating non channelized flows over a flat topography. Advances in upwind shock-capturing numerical schemes and two-dimensional topography provided by graphical information systems (GIS) and remote sensing technologies have led to the development of robust two-dimensional flood simulation models that can be used for engineering studies. Despite considerable advances in CPU speeds of modern computers, two-dimensional models require relatively longer computational times due to small time step imposed by rather restrictive stability conditions associated with explicit time integration. Existing two-dimensional models are generally too slow for operational forecasting purposes, which require faster-than-real-time simulation speeds.
In the past there have been many attempts to speed up two-dimensional models. USGS has experimented with near-real time flood simulations using TRIMR2D model developed by Casulli, University of Trento, Italy. Despite ingenuous use of semi-implicit, semi-Lagrangian finite difference techniques, only near-real-time simulation speeds could be achieved. Game programmers have succeeded in obtaining real-time simulation speeds by simplifying and/or linearizing governing shallow water equations. Unfortunately, although visually plausible, the results produced by these overly simplified models cannot be used for engineering purposes. More recently, Smoothed Particle Hydrodynamics (SPH) and Lattice Boltzman method (LBM) have been proposed to achieve higher computational speeds. However, these methods constitute approximations to real flow phenomena and defining certain physical parameters, such as viscosity, may be a problem. Parallel computing on mainframe supercomputers can offer significant increase in computing speeds, but remain outside of the reach of ordinary users.
The recent developments in programmable graphics cards commonly present in desktop and laptop computers now bring parallel computing power to the realm of personal computers. The seminar will present a two-dimensional numerical model, which can perform faster-than-real-time flood simulation and visualization by exploiting these developments and the emerging GPGPU (General-Purpose computation on GPUs) techniques. The numerical model uses the second-order accurate central-upwind scheme of Kurganov-Petrova to solve shallow water equations over a complex topography. The model offers both Euler and 2nd order Runge Kutta time integration. It can handle wetting and drying, disconnected flow domains, and mixed flow regimes. A slope limiter is used to capture sharp interfaces without spurious oscillations. This numerical model is incorporated into a computer-game like environment with simultaneous visualization and interactive user functions to zoom in and out, pan, and rotate the computational domain. The user is also given the possibility to reel back the solution to a specified time, modify the terrain and continue the simulation to see the effects of the changes. Developed with funding from the Department of Homeland Security-sponsored Southeast Region Research Initiative (SERRI) at the Department of Energy’s Oak Ridge National Laboratory, USA, this tool currently focuses primarily on dam-break modeling. However, it can be cost-effectively modified to suit the needs of NWS as an operational forecasting tool.
The numerical model and its implementation on GPGPU using CUDA language will be presented and several examples will be shown. The computational speed of the model will be demonstrated by running some test cases on a laptop and by visualizing the results.

Abstract: |
Several of NOAA’s Fisheries Science Centers and Regional Offices have been working on a broad suite of seabird issues since the early 1980’s. This work involves seabird bycatch monitoring and reporting, coordination with other Federal Agencies (US Fish and Wildlife Service and US Geological Survey), addressing Endangered Species Act issues, and collaborative work (with industry and academia) to develop seabird bycatch reduction approaches. Some work also explored or described the role of seabirds in marine ecosystems and how they quickly respond to changes in the ocean environment. Seabird work was being developed independently at several sites and with few resources. The need for coordination, continued international work, and development of funding sources led to the establishment of a National Seabird Program in 2001. With very limited resources, the program supports studies on fisheries bycatch of seabirds and the development of solutions to mitigate and reduce fishing gear impacts on seabirds both domestically and internationally. The program is also expanding its scope to provide better support to Regions and Centers in their work to understand seabirds exclusive of bycatch issues. We know that seabirds are important indicators of marine ecosystem health. Seabird distribution and abundance can reflect physical and biological oceanography, abundance and distribution of mid trophic-level organisms, and the effects of climate change on apex predators. Contaminant levels in seabirds can provide insight into the health of a particular ecosystem. And, unlike so many marine organisms, seabirds are relatively easy and cost-effective to sample. With the ever increasing recognition of the vital role seabirds have within the marine ecosystem, and the continued importance of bycatch monitoring and mitigation, NOAA scientists and managers acknowledge the need for continued support of seabird studies. This seminar will offer highlights of some of the key activities of the NOAA Fisheries’ Seabird Program, including describing some of its projects, as well as touching on other seabird work within NOAA. |

Abstract: |
Over the past 12 million years, a diversity of mammals evolved
specializations for exploiting Arctic sea ice. Other marine mammals—lacking
adaptations to ice—have been isolated from one another by sea ice and have
evolved along separate paths in the North Atlantic and North Pacific oceans.
For the past 10,000 years, Arctic people have developed cultures around the
seasonal availability of Arctic marine mammals. Today, 11 ice-associated
marine mammal species face unprecedented rapid loss of a continent-sized
habitat as Arctic sea ice diminishes. A skeptical analysis (a first
principal of science) of ecological and evolutionary data indicate that rapid changes in food resources, predation, competition, and interbreeding
threaten many species as well as traditional ways of life among Arctic
people. Responding to these changes will require sound analyses, mitigation,
and adaptation.

Abstract: |
Oceanic and coastal waters are known to harbor and transport microorganisms that cause disease in humans and other animals. While certain pathogenic microorganisms, including Vibrio spp., occur naturally in marine and estuarine waters, anthropogenic contaminants including enteric bacteria, protozoa and viruses may be introduced to coastal waters as sewage pollution. Despite the relatively unfavorable environment, these introduced organisms may survive for prolonged periods in the marine environment; and, it remains unclear how human pathogenic microbes interact in the complex estuarine environment and how those interactions ultimately affect their fate. We are exploring the role of plankton as a defined niche for a suite of microbial pathogens, both native and sewage-associated. We hypothesize that the high level of surface area represented by plankton would present a natural zone for microbial accumulation, in general, and that the specific composition of the plankton community would influence population dynamics in Vibrio spp. in particular. We examined the interactions between plankton, Vibrio spp., human enteric viruses and traditional fecal indicator bacteria in estuaries of coastal Georgia. Consistent with previous findings, Vibrio spp. were highly concentrated in the plankton fractions relative to the water column. Vibrio concentrations were also positively associated with copepod abundance in the small plankton fraction, when temperature and salinity were controlled. Both enterococci and fecal coliform bacteria were also found in higher concentrations in plankton fractions but varied in magnitude of enrichment over the study period; however, plankton-associated enterococci contributed up to 95% of the total enterococci load during summer months. Additionally, the human enteric noroviruses were found at their highest concentrations in the plankton, at up to 1014 genomes g-1. While this project started with the aim of expanding our understanding of the known relationship between Vibrio spp. and plankton our results suggest that microbial association among these phytoplankton and zooplankton groups may be a general phenomenon. It also suggests that plankton may provide critical refuge for many enteric microbes in an estuarine setting and thus enhance persistence and increase chances for human exposure.

Abstract: |
NOAA’s National Centers for Coastal Ocean Science has completed a collaborative project titled “Assessment of Existing Information on Atlantic Coastal Fish Habitats: Development of a web-based spatial bibliography, query tools, and data summaries”, and published the results in a Technical Memorandum. The Assessment includes three components: 1) a representative bibliographic and assessment database,
2) a Geographical Information System (GIS) spatial framework, and 3) a published summary report with description of methods, analyses of habitat assessment information, and recommendations for further work. The spatial bibliography was created by linking the bibliographic table developed in Microsoft Excel and exported to SQL Server, with the spatial framework developed in ArcGIS and exported to GoogleMaps. Information on habitat condition indicators, threats, and conservation recommendations are extracted from each entry and recorded in a separate linked table. Together, the bibliography and assessment tables and their spatial framework provide a powerful tool to query and assess available information through a publicly available web interface. The project is a cooperative effort of NOAA/NOS Center for Coastal Monitoring and Assessment (CCMA) Biogeography Branch and Atlantic Coastal Fish Habitat Partnership (ACFHP). The results are assisting conservation planning by the Partnership, and the general approach is being applied towards the coastal component of the National Fish Habitat Action Plan (NFHAP) 2010 Assessment.
A PDF version of the report, along with additional information, is available at: http://ccma.nos.noaa.gov/ecosystems/estuaries/coastalfish.html, and the web-based query tools are accessible at: http://www8.nos.noaa.gov/bhv/spatbibindex.html. |

Hybridization Between Native Westslope Cutthroat Trout and Introduced Rainbow Trout: Genomic Extinction or Adaptive Evolution?
|

Abstract: |
Human-mediated hybridization is a leading cause of biodiversity loss worldwide. How hybridization affects ecological adaptations and what level of hybridization is permissible pose difficult conservation questions with little empirical information to guide policy and management decisions. This is particularly true for salmonids, where widespread introgression among nonnative and native taxa has often created hybrid swarms over extensive geographic areas resulting in genomic extinction. Interbreeding between westslope cutthroat trout (Oncorhynchus clarkii lewisi) with nonnative rainbow trout (O. mykiss) exemplifies the conservation challenges of interspecific hybridization. Clint will present over 10 years of research in Montana that has investigated the behavioral, ecological, and fitness consequences of hybridization and the factors influencing the spread of hybridization between native westslope cutthroat trout and introduced rainbow trout. The combined results suggest that hybrids are not only genetically different than westslope cutthroat trout but also have reduced fitness and are ecologically different, and that hybridization is likely to continue to spread if hybrid populations with high amounts of rainbow trout admixture are not reduced or eliminated. Results indicate that extant aboriginal cutthroat trout are at greater conservation risk due to hybridization than previously thought and policies that protect hybridized populations need reconsideration.
