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.

Landscape controls river continuum dissolved organic carbon in northeastern Alaska Landscape controls river continuum dissolved organic carbon in northeastern Alaska
Rivers draining continuous permafrost landscapes on the North Slope of Alaska span from the mountains to the coast, integrating gradients in vegetation, soil organic matter, and hydrologic flow. We investigated how these landscape transitions influence dissolved organic carbon (DOC) concentrations, radiocarbon ages, and export along the river continuum over seasonal timeframes in...
DRIFteRS: A dataset of drift invertebrate densities in streams and rivers across western North America, 1997–2024 DRIFteRS: A dataset of drift invertebrate densities in streams and rivers across western North America, 1997–2024
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...
Biomarkers of mortality risks in Yukon Chinook salmon Biomarkers of mortality risks in Yukon Chinook salmon
Premature mortality of spawning adult Pacific salmon (Oncorhynchus species) can strongly influence population dynamics and complicate escapement-based management. Heat stress and Ichthyophonus infections have been identified as probable drivers of premature mortality in Yukon River Chinook salmon (Oncorhynchus tshawytscha) and likely contributors to low spawning abundance. We leveraged a

Wolverine Glacier
Wolverine Glacier is located in Alaska’s Kenai Mountains, along the western flank of Prince William Sound. Glacier observations began in 1966 and continue through present as the western most USGS Benchmark Glacier.
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.
Alaska Landbird Monitoring Survey
Alaska provides breeding habitat for more than 140 regularly occurring species of landbirds, half of which breed predominantly north of the U.S.–Canada border. The road-based North American Breeding Bird Survey (BBS) provides some data on population trends in Alaska, but most northern species are inadequately monitored by that continental program because of a paucity of roads. Boreal Partners in...
