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.

Streambed scour is the leading cause of bridge failure in the United States resulting in over 60 percent of all failures. Since 1993 the U.S. Geological Survey (USGS) has worked with the Alaska Department of Transportation and Public Facilities to provide hydraulic assessments of scour for bridges throughout Alaska.

Local environmental conditions structured discrete fish assemblages in Arctic lagoons
Rapid changes in sea ice extent and changes in freshwater inputs from land are rapidly changing the nature of Arctic estuarine ecosystems. In the Beaufort Sea, these nearshore habitats are known for their high productivity and mix of marine resident and diadromous fishes that have great subsistence value for Indigenous communities. There is, however, a lack of information on the spatial variation
Deep-water first occurrences of Ediacara biota prior to the Shuram carbon isotope excursion in the Wernecke Mountains, Yukon, Canada
Ediacara-type macrofossils appear as early as ~575 Ma in deep-water facies of the Drook Formation of the Avalon Peninsula, Newfoundland, and the Nadaleen Formation of Yukon and Northwest Territories, Canada. Our ability to assess whether a deep-water origination of the Ediacara biota is a genuine reflection of evolutionary succession, an artifact of an incomplete stratigraphic record, or a bathyme
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

North Pacific Pelagic Seabird Database
The North Pacific Pelagic Seabird Database (NPPSD) contains survey transect data designed and conducted by numerous partners primarily to census seabirds at sea. The NPPSD includes more than 486,000 transect segments and includes observations of over 20 million birds of 258 species collected over the span of 50 years (from 1973 to 2022).
Understanding PGE, Cr, Ni and Cu Potential in Ophiolitic Rocks in Alaska
Ophiolites are sections of oceanic lithosphere that have been structurally emplaced onto continental crust. The ultramafic components of some ophiolites contain podiform chromitites, an important potential source of several strategic and critical minerals, including chromium and platinum group elements (PGE). Yet the tectonics and petrogenesis of several Alaskan ophiolites is poorly understood...
Walrus Research
The USGS Alaska Science Center conducts long-term research on the Pacific walrus to provide scientific information to Department of Interior management agencies and Alaska Native co-management partners. In addition, the USGS Pacific walrus research program collaborates with the U.S. Fish and Wildlife Service (USFWS) and the State of Alaska’s Department of Fish and Game and Alaska Native co...
