Marine Ecosystem Monitoring in the Northern Gulf of Alaska
Oceanographic data were primarily collected from the University of Alaska's School of Fisheries and Ocean Science research
vessel, the R/V
Alpha Helix from 1997-2004, under funding from the Northeast Pacific GLOBEC program. Data collection from 2004 to the present has been supported by the North Pacific Research Board (NPRB), on cruises aboard the R/V Thomas G. Thompson and the M/V Tiglax. Fisheries data were collected on the
Alaska Dept.of Fish and Game research vessel, the R/V Pandalus. Stations are
occupied in the northern Gulf of Alaska primarily along the Seward Line and a few stations within
Prince William Sound. Other stations are
occupied on an opportunistic basis as time and weather (!) permit. The location
of the sampling lines and station GAK1 are shown on the station location map.
Processed data can be obtained from the GLOBEC JGOFS web data server, from
the NODC data archives, or by email request.
Depth-Integrated Physical Hydrography, 1998-Present
To show the current May and September data within the context of the sampling done since 1998, we integrated the 0-100, 100-250 and 250-275 decibar levels across the Seward Line for temperature and salinity. Note: Some years we have only September data and some years we have averaged the August and October data. This averaging may produce some artifacts. |
