+--------------------------------------------------------------------------+ | OCEANUS CRUISE SYNOPSIS | +--------------------------------------------------------------------------+ Voyage - Leg: OC 408-2 Voyage Dates: 15 Feb - 15 Mar 2005 Chief Sci(s): Michael Lomas (Lomas/Jenkins) Address: Bermuda Biological Station 17 Biological Lane St. George's, GE01 BERMUDA Phone: 441-297-1880 x303 Email: mlomas@bbsr.edu Cruise Objective: 1) Measure the daily time course of N input and uptake, within the euphotic zone of the Sargasso Sea, through several destratification/stratification events during the winter convective mixing period. 2) Quantify the main floristic changes (using a diversity of chemotaxonomic methods) and the size distribution change in the phytoplankton community during and after these destratifica-tion/stratification events. 3) Determine the fate of N (primarily particulate flux, DON export, non-gravitational flux or remineralization) that is detrained during destratification events in order to better understand the relationships between new production and export production. 4) Use the data collected to validate and enhance a 1-D model of the primary production and biogenic particle export cycle that has been developed for the BATS site, as well as increase the general robustness of biological/physical models for this and similar temperate latitude sites. Science Activities: CTD, ADCP, XBT's, Plankton net tows, PITS deployment/Recovery Operations Area: Sargasso Sea 32N 64W 0-4000m SSSG Tech: sssg @oceanus.whoi.edu Departure Port: St. Georges, Bermuda Agent: Meyer Shipping Somers Wharf 14 Water St. St. Georges, GE BX BERMUDA Contact: Capt.

Jenkins/Lott Lab Van - cable and plug provided Shipboard Equipment/Nav: Other Requirements: Equipment will be deployed through stern A-frame; stowage, large number of sample bottles Notes: Three Overboarding events, a 400m surface tethereed sediment trap array, a surface tethered incubation array as done in 2004 and net tows. Night Work Anticipated - night program to consist of 2 CTD casts and possible net tow. Radioisotopes will be stored in special poly lined barrels. In 2004 we purchased appropriate barrels from WHOI, we wish to do this again. Chemical Waste, weak acids, formaldehyde and nutrient autoanalyzer waste will be stored in drums on the weather deck and will be removed in Bermuda at the completion of the cruise. All stock chemical brought on board and not used will be removed in Bermuda. We will have HCl acid on board for cleaning sampling gear during the course of the cruise. Ideally this will be stored out on deck in an appropriate chemical storage locker. Chemical inventory sheets for our 2005 cruise are nearly identical to those used in our 2004 cruise. Supplies for cleaning up spills will be brought on board as well as all appropriate protective gear (lab coats, safety glasses, etc.).
