AFSC/RACE/GAP/ZIMMERMANN: Bathymetry: western Gulf of Alaska Grid
We defined the bathymetry of Shelikof Strait and the western Gulf of Alaska (WGOA) from the edges of the land masses down to about 7,000 m deep in the Aleutian Trench. We made... -
AFSC/RACE/GAP/Zimmermann and Prescott: Eastern Bering Sea Slope Grid
We created a new, 100 m horizontal resolution bathymetry raster and used it to define 29 canyons of the eastern Bering Sea (EBS) slope area off of Alaska, USA. To create this... -

The Chukchi and East Siberian Surveys (ChESS) were a joint U.S.-Russian effort to enumerate ice-associated seals and polar bears in the Chukchi and East Siberian seas. ChESS is... -
Bering-Okhotsk Seal Survey (BOSS) Identified Hot Spots (2012-13)
US surveys were conducted of the Bering Sea pack ice for bearded, spotted, ribbon, and ringed seals using digital cameras and thermal imagers mounted in the belly ports of two... -
Bearded Seal Distribution
This dataset contains GIS layers that depict the known spatial distributions (i.e., ranges) of the two subspecies of bearded seals (Erignathus barbatus). It was produced as part... -
Aerial Survey Counts of Harbor Seals in Coastal Alaska (1998-2002)
This dataset supports efforts to estimate the abundance and trends in population size of Alaska harbor seals. Annual surveys of harbor seal populations are fundamental to... -
Alaska Harbor Seal Glacial Surveys
Floating glacial ice serves as a haul-out substrate for a significant number (10-15%) of Alaskan harbor seals, and thus surveying tidewater glacial fjords is an important... -
Ringed Seal Distribution
This dataset contains GIS layers that depict the known spatial distributions (i.e., ranges) of the five subspecies of ringed seals (Phoca hispida). It was produced as part of a... -
