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.

Selected special conditions affecting peak streamflow and extreme floods in Alaska through water year 2022 Selected special conditions affecting peak streamflow and extreme floods in Alaska through water year 2022
The U.S. Geological Survey, in cooperation with the Alaska Department of Transportation and Public Facilities, inventoried selected special conditions for annual peak flows and identified extreme floods at streamgages in Alaska through water year 2022 to facilitate hydrologic analysis. Special conditions identified from U.S. Geological Survey gaging records and basin characteristics...
Identifying presence or absence of grizzly and polar bear cubs from the movements of adult females with machine learning Identifying presence or absence of grizzly and polar bear cubs from the movements of adult females with machine learning
BackgroundInformation on reproductive success is crucial to understanding population dynamics but can be difficult to obtain, particularly for species that birth while denning. For grizzly (Ursus arctos) and polar bears (U. maritimus), den visits are impractical because of safety and logistical considerations. Reproduction is typically documented through direct observation, which can be...
Arctic speleothems reveal nearly permafrost-free Northern Hemisphere in the Late Miocene Arctic speleothems reveal nearly permafrost-free Northern Hemisphere in the Late Miocene
Arctic warming is happening at nearly four times the global average rate. Long-term trends of permafrost dynamics cannot be estimated directly from monitoring of present-day thaw processes, requiring paleoclimate-proxy information. Here we use cave carbonates (speleothems) from a northern Siberian cave to determine when the Northern Hemisphere was mostly permafrost-free. At present...

Tracking Data for Long-billed Curlews (Numenius americanus)
Available here are tracking data for the largest shorebird in North America, the long-billed curlew. This species nests in deserts and grasslands of central and western North America and spends the nonbreeding season in agriculture fields and pastures or along coastlines in California, Texas, and Mexico. These data were collected to better understand the migratory patterns of this unmistakable and...
Tracking Data for Buff-Breasted Sandpipers (Calidris subruficollis)
Available here are tracking data of buff-breasted sandpiper, a shorebird species that breeds only in Arctic Alaska and Canada, spending the winter in the grasslands of Brazil, Uruguay, and Argentina after a lengthy migration. These data were collected to determine range-wide migratory routes, migratory timing, and stopover habitats of this species.
Tracking Data for Long-tailed Ducks (Clangula hyemalis)
Available here are tracking data of long-tailed duck, a species of seaduck that breeds throughout the circumpolar Arctic and spends the winter in coastal areas of northern and mid latitudes. These data were collected to determine range-wide migratory routes, migratory timing, and stopover habitats of this species.
