Alaska Region

USGS in Alaska conducts science for decision-making in five major areas: natural hazards; energy & minerals; water quality, streamflow & ice; wildlife, fish & habitat; and geospatial mapping. The Alaska Regional Office provides management and strategic coordination among the Alaska Science Center, the Volcano Science Center, & other partners operating in AK.

Prey availability is among the most influential and highly variable determinants of fish growth and freshwater habitat carrying capacity, yet it remains understudied compared to physical habitat variables (Ouellet et al., 2025; Rosenfeld et al., 2014; Weber et al., 2017). We often lack a clear understanding of how much food is available to fishes, how it varies spatially and temporally...

Climate change vulnerability assessment for guiding ecosystem restoration in fire-prone landscapes of the western U.S. Climate change vulnerability assessment for guiding ecosystem restoration in fire-prone landscapes of the western U.S.

Climate-driven alterations to fire regimes challenges forest management and restoration in the western United States, where increased wildfire severity threatens ecosystem integrity and resilience. In this study, we demonstrate the application of the FireCLIME (Fire-Climate-Landscape Interactions in Montane Ecosystems) Vulnerability Assessment (VA) as a decision-support tool for...

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...

Geologic Map of Alaska

In January 2016, the U.S. Geological Survey released the first ever digital geologic map of Alaska. This map reflects more than a century of work and provides a visual context for the abundant mineral and energy resources found throughout the state. The map also is available to use in three different formats: a professional GIS database, a public interactive version via a web browser, and an...

Gulkana Glacier

Gulkana Glacier is located in the high-latitude continental climate regime of Alaska’s Delta Mountains. Glacier observations began at this site in 1966 and continue through present as the northern most USGS Benchmark Glacier.
