Glacier Bay National Park and Preserve Sea Otter Forage Data, 1993-2019

These data describe observations of sea otter foraging behavior in Glacier Bay National Park and Preserve. Data consist of dive and surface times, success in prey retrieval, prey item, prey quantity, and size. Additionally, location of observations, and age class, sex, and pup status of the focal sea otter were also recorded.

Sea Otter Spraint Data from Kachemak Bay, Katmai National Park and Preserve, Kenai Fjords National Park and Prince William Sound

These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program. This dataset consists of observations of sea otter (Enhydra lutris) fecal samples (spraint). Observers examined fresh spraint piles to identify major prey classes in the samples and to determine sea otter diets in the Gulf of Alaska region.

Alaska Forage Fish Database (AFFD)

The Alaska Forage Fish Database (AFFD) is a consolidation of survey data from multiple agencies that were sampled via fishing gear and predator diets. The spatial coverage includes the Gulf of Alaska, Bering Sea, Aleutian Islands, Chukchi Sea, and Beaufort Sea. Fish species within the database include Pacific sand lance, Pacific capelin, Pacific herring, juvenile walleye pollock and Pacific cod, myctophid, squid, and euphausiid. The data package is comprised of six tables: (1) catch_table includes counts, weight, and individual morphological characteristics (length, sex, age) of the sampled species; (2) event_table includes sampling time, location, and methods; (3) gear_table includes specifics about of the gear...
