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.

Where east meets west: Phylogeography of the high Arctic North American brant goose

Genetic variation in Arctic species is often influenced by vicariance during the Pleistocene, as ice sheets fragmented the landscape and displaced populations to low- and high-latitude refugia. The formation of secondary contact or suture zones during periods of ice sheet retraction has important consequences on genetic diversity by facilitating genetic connectivity between formerly isolated popul

A high-resolution, daily hindcast (1990-2021) of Alaskan river discharge and temperature from coupled and optimized physical models

Water quality and freshwater ecosystems are affected by river discharge and temperature. Models are frequently used to estimate river temperature on large spatial and temporal scales due to limited observations of discharge and temperature. In this study, we use physically based river routing and temperature models to simulate daily discharge and river temperature for rivers in 138 basins in Alask

Predator disturbance contributed to Common Murre Uria aalge breeding failures in Cook Inlet, Alaska following the 2014–2016 Pacific marine heatwave

The 2014-2016 Pacific marine heatwave caused unprecedented die-offs and multi-year reproductive failures for Common Murres Uria aalge along the west coast of North America. Lingering impacts, such as declines in colony attendance and productivity, have persisted at some colonies following the heatwave and are attributed largely to changes in prey availability and quality. Here, we present evidence

Streambed Scour at Bridges in Alaska

Streambed scour is the leading cause of bridge failure in the United States resulting in over 60 percent of all failures. The Alaska Science Center, in cooperation with the Alaska Department of Transportation and Public Facilities and the Alaska Railroad, is researching streambed scour through scour monitoring, hydraulic modeling, and data collection during high flows.

Collaborative Science for Priority Information Needs

One of the primary missions of the USGS is to address the science needs of Department of Interior bureaus, particularly those that manage natural resources and lands. This mission is fulfilled through the research and other activities of USGS scientists but also specifically through three USGS nationally-funded programs listed below.

Q&A: The Alaska Landbird Monitoring Survey

Alaska provides breeding habitat for more than 140 regularly occurring species of landbirds, a group that includes woodpeckers, songbirds, ravens and jays, raptors, and other land-dwelling species like grouse and ptarmigan. The Alaska Landbird Monitoring Survey (ALMS) tracks the breeding populations of landbirds in the vast off-road areas of Alaska.
