To this aim, eleven projects are supported on this cruise. [1]http://test.nprb.org/bsierp/proj_mgt/cruise_planning.html Science The cruise begins with an ichthyoplankton -zooplankton survey Activities: along a series of stations from Unimak Pass into Bristol Bay. That work continues as we start occupying standard stations along four major cross-shelf transects. These transects are: the CN line (southernmost southwest to northeast, ending at Cape Newenham, AK); the NP Line from Nunivak I. to off shore of St Paul Island; the MN Line (central, east-west) starting from Nunivak I., passing south of St. Matthews I., then over the outer shelf and slope to deep water; and the SL Line (northernmost) lies south of St. Lawrence I. (see attached map). Another transect, the W line, extends inshore from the 70 m line to intersect a series of moorings. Following completion of the major cross-shelf transects, work will be conducted on the WOCE-P14 line in open water. At the end of the cruise we will occupy the 58-station 70-m isobath line from north to south, which intersects four long-term moorings maintained by PMEL NOAA. The four moorings are: M2, M4. M5 and M8. Each transect consists of a series of stations at which several sampling activities are routinely conducted, including CTD casts with a 12x30-liter rosette, and CalVET net tows. At night, bongo nets and MOCNESS operations are added. More intensive sampling is conducted every other day at Process Stations, where a fuller suite of sampling and experimentation are conducted to measure phytoplankton, microzooplankton, mesozooplankton (copepods, krill), benthic composition and selected rates (e.g., grazing, reproduction, nutrient regeneration, production). Other sampling (e.g., benthic grabs, plankton tows, benthic cores) is conducted several times per day at selected locations. At least 200 CTD casts and 50-60 MOCNESS tows are planned. At process stations many of activities involve multiple CTD casts to collect water for incubations. It is expected that there will be 4-5 deployments of 18-24 hr duration of the sediment trap array over the slope. The traps have been easy to track and no trouble to re-locate after previous deployments. It is expected that we will take ~18 multicores, including 2-4 in waters at the base of the continental slope. Bird watchers plan to make observations from the bridge during daylight hours, using their own equipment.
