Alaska Critical Mineral Resource Assessments
Alaska has potential for a wide range of critical minerals including, but not limited to, graphite, lithium, tin, tungsten, rare earth elements, and platinum-group elements.

Alaska Science Center
The mission of the Alaska Science Center (ASC) 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.

Indicators of mercury concentration in Lake Trout: Can fish location and appearance provide information to anglers to reduce their exposure? Indicators of mercury concentration in Lake Trout: Can fish location and appearance provide information to anglers to reduce their exposure?
Objective People are exposed to mercury (Hg) through the consumption of fish. State and federal governments provide broad, often-generalized food safety guidance to reduce exposure; however, numerous rural fishing areas lack testing and location- or species-specific guidance. The aim of this study was to provide tangible, visible, or easily measured characteristics of Lake Trout...
Tringa flavipes (Lesser Yellowlegs) from separate breeding sites subdivides the Prairie Pothole Region in space and time during southbound migration Tringa flavipes (Lesser Yellowlegs) from separate breeding sites subdivides the Prairie Pothole Region in space and time during southbound migration
Some staging regions support multiple groups of the same migratory species, each of which may use the region differently. Characterizing the ways, in which separate groups use such regions can therefore help to identify vulnerabilities during this sensitive period of the annual cycle. The Prairie Pothole Region (PPR) is a massive wetland complex in the northern Great Plains of North...
Refinement of a framework for Moving Aircraft River Velocimetry (MARV) and application to particle tracking along Alaskan rivers Refinement of a framework for Moving Aircraft River Velocimetry (MARV) and application to particle tracking along Alaskan rivers
Information on river velocities enhances understanding flood hazards, evaluating habitat conditions, and predicting the transport of floating materials. In this follow-up study, we used data from two new sites, one with a more complex morphology and the other with a lower suspended sediment concentration, to provide further evidence that Moving Aircraft River Velocimetry (MARV) can yield...

Landbird Research in Alaska
On this page, learn about USGS work with the Alaska Landbird Monitoring Survey (ALMS), Beak Deformities in Landbirds, and Boreal Partners in Flight (BPIF).
Polar Bear Research
Polar bears ( Ursus maritimus) are one of 4 marine mammal species managed by the U.S. Department of Interior. The USGS Alaska Science Center leads long–term research on polar bears to inform local, state, national and international policy makers regarding conservation of the species and its habitat. Our studies, ongoing since 1985, are focused on population dynamics, health and energetics...
Shorebird Research
With its vast size and geographic position at the northern end of several migration pathways, Alaska is a critically important site for the world’s shorebirds. Thirty-seven shorebird species regularly breed in Alaska. Most of these species conduct epically long migrations to take advantage of Alaska’s abundant food resources and breeding habitat, making Alaska a global resource for shorebirds...
