Alaska Science Center

The mission of the Alaska Science Center is to provide objective and timely data, information, and research findings about the earth and its flora and fauna to Federal, State, and local resource managers and the public to support sound decisions regarding natural resources, natural hazards, and ecosystems in Alaska and circumpolar regions. We have offices in Anchorage, Juneau, and Fairbanks.

Brown bear–sea otter interactions along the Katmai coast: Terrestrial and nearshore communities linked by predation

Sea otters were extirpated throughout much of their range by the maritime fur trade in the 18th and 19th centuries, including the coast of Katmai National Park and Preserve in southcentral Alaska. Brown bears are an important component of the Katmai ecosystem where they are the focus of a thriving ecotourism bear-viewing industry as they forage in sedge meadows and dig clams in the extensive tidal

Lingering impacts of the 2014-2016 northeast Pacific marine heatwave on seabird demography in Cook Inlet, Alaska (USA)

A protracted period (2014-2016) of anomalously warm water in the northeast Pacific Ocean precipitated an extensive die-off of common murres Uria aalge (hereafter ‘murres’) during 2015-2016, accompanied by reduced colony attendance and reproductive success of murres and black-legged kittiwakes Rissa tridactyla (‘kittiwakes’) starting in 2015. Most murres died of starvation following a large-scale r

Flyway-scale GPS tracking reveals migratory routes and key stopover and non-breeding locations of lesser yellowlegs

Many populations of long-distance migrant shorebirds are declining rapidly. Since the 1970s, the lesser yellowlegs (Tringa flavipes) has experienced a pronounced reduction in abundance of ~63%. The potential causes of the species' decline are complex and interrelated. Understanding the timing of migration, seasonal routes, and important stopover and non-breeding locations used by this species will

U.S. Fish and Wildlife Service Tracking Data for Steller's Eiders (Polysticta stelleri)

Available here are tracking data of the Steller’s Eider, a species of seaduck that breeds throughout the circumpolar Arctic and spends the winter in coastal areas of western and southwestern Alaska. The Alaska-breeding population is listed as threatened under provisions of the Endangered Species Act. These tracking data were collected by the U.S. Fish and Wildlife Service. The entire data package...

Q&A: Estimates of Abundance for Pacific Walrus

The Pacific walrus ranges across the Bering and Chukchi seas during the year. This wide geographic distribution makes it difficult to estimate Pacific walrus population abundance. However, recent technological advances in genetics and drone imagery have generated precise regional and range-wide abundance estimates.
