Samples in the Northern Gulf of Alaska (NGA) along the Seward Line set of hydrographic stations have been collected on interdisciplinary cruises since October, 1997.
Located at the mouth of Resurrection Bay near Seward, Alaska, temperature and salinity versus depth profiles have been taken at oceanographic station GAK1 since December, 1970.This multi-decade time series is one of the longest running oceanographic time series in the North Pacific.
This collaborative ecosystem research cruise's goal is to evaluate status and change of the ecosystem and recover and re-deploy ocanographic moorings. The effort includes NOAA Distributed Biological Observatory (DBO)/Ecosystems & Fisheries Oceanography Coordinated Investigations (EcoFOCI) , the Arctic Marine Biodiversity Observation Network (AMBON) and the Chukchi Ecosystem Observatory (CEO) programs. Activities include hydrographic and biological surveys consisting of hydrographic CTD/rosette sampling, zooplankton and larval fish bongo net tows, van veen grabs and HAPS coring for sediment sampling, and beam trawling for epibenthic collections at designated sites.
In partnership with the National Park Service, we undertake surveys in the eastern Gulf of Alaska outer coast region, with particular focus on the coastal fjords of Disenchantment Bay, Yakutat Bay, Icy Bay and Lituya Bay. The UAF Oceans Lab deploys a mooring in Disenchantment Bay and collects water column hydrography data. Dr. Jenn Questel of UAF leads sampling for zooplankton, nutrients, ocean acidification, chlorophyll a, and environmental DNA.
In partnership with Canada's Department of Fisheries and Oceans (DFO), we participate in the Kitikmeot Sea Science Study in the Canadian Arctic Archipelago's Northwest Passage. Cruises are based out of Cambridge Bay and typically visit Coronation Gulf, Bathurst Inlet and Queen Maud Gulf. Read more about the K3S project goals and results. Collaborators include Drs. Bill Williams and Mike Dempsey (both at DFO), Kristina Brown (University of Manitoba), and Eddy Carmack (ret.) of Canada and Bodil Bluhm (Arctic University of Norway). Blog entries from our work provide notes from the field.
