Research Expedition to the Gulf of Alaska - TN263
Research Vessel Thomas G. Thompson
Gulf of Alaska - Integrated Ecosystem Research
April 30 - May 21, 2011
|Welcome to the web site for our spring Gulf of Alaska research cruise.
R/V Thomas G. Thompson is our platform for three weeks while we measure ocean conditions and look at the ecosystem of the Gulf in near-shore, shelf and shelf-slope areas of Southeast Alaska. Our activities fit into a larger multi-year project addressing the interrelationship of climate, oceanography, fisheries, ocean biology,
ocean chemistry, and seabirds in a changing ecosystem. This spring expedition is funded through the GOA-IERP program in conjunction with NOAA's NPCREP program, and funded by the North Pacific Research Board and NOAA.

|Operations primarily consist of zooplankton sampling, hydrographic measurements,
water sampling and iron sampling. We will conduct bongo tows, Neuston net tows, and MOCNESS tows. Hydrography includes digital profiles of temperature, salinity (calculated from temperature and conductivity), pressure, chlorophyll and oxygen. We also take CTD water samples for phytoplankton, zooplankton, nutrient and oxygen analysis. We are sampling at pre-defined "transect" lines of stations in the area.
