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.

Glaciers and Landscape Change
The USGS Benchmark Glacier Project is aimed at solving complex scientific problems in snow and ice across North America to promote enhanced monitoring, analysis, and prediction of mountain glacier change.

Potential warming-induced changes in stream water sources between proglacial and non-glacial streams, south-central Alaska Potential warming-induced changes in stream water sources between proglacial and non-glacial streams, south-central Alaska
Snow and ice-melt are essential for global water resources. Rising air temperatures are causing vegetation encroachment and shrubification of previously snow- and ice-covered landscapes, and precipitation regimes are changing. Collectively, these changes will likely affect the hydrology of mountain environments, although the exact ways in which the hydrology will change are poorly...
Integrating detrital magnetite geochemistry and (U-Th)/He chronometry as a sediment provenance tool in geologic and metallogenic terranes Integrating detrital magnetite geochemistry and (U-Th)/He chronometry as a sediment provenance tool in geologic and metallogenic terranes
Magnetite is ubiquitous in porphyry Cu systems and in sediment sourcing both barren and mineralized regions, with potential as an indicator mineral in concealed and coarsely-mapped terranes. We develop and test a workflow for integrated geochemistry and (U–Th)/He (He) dating for inferring detrital magnetite (DMt) provenance in these settings. The ca. 70 Ma Taurus porphyry Cu–Mo(–Au)...
Testing the efficacy of industrial mitigation measures for caribou in the Arctic Testing the efficacy of industrial mitigation measures for caribou in the Arctic
1. Mitigation measures are commonly employed to reduce the negative effects of industrial development on wildlife but are not often evaluated for their efficacy. For example, oil fields in the Arctic typically incorporate design features intended to increase permeability for migratory, barren-ground caribou (Rangifer tarandus), even though there is limited empirical evidence of the...

Lemon Creek Glacier
Lemon Creek Glacier is located in southeast Alaska, at the southernmost tip of the Juneau Icefield. Glacier observations began at this site in 1953 and continue through present, serving as a central site between glaciers in the contiguous USA and those in mainland Alaska.
Glaciers and Landscape Change
Mountain glaciers are dynamic reservoirs of frozen water, deeply interconnected with their surrounding ecosystems. Glacier change in North America has major societal impacts, including to water resources, natural hazard risk, tourism disruption, fisheries, and global sea level change. Understanding and quantifying precise connections between changing glaciers, the surrounding landscape and climate...
Terrestrial Mammal Research
Understanding the population dynamics, predator/prey relationships and habitat ecology of terrestrial mammals, such as caribou and muskoxen, is critical for the management of these species and their habitats in Alaska.
