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.

Satellite Interferometry Landslide Detection and Preliminary Tsunamigenic Plausibility Assessment in Prince William Sound, Southcentral Alaska

Regional mapping of actively deforming landslides, including measurements of landslide velocity, is integral for hazard assessments in paraglacial environments. These inventories are also critical for describing the potential impacts that the warming effects of climate change have on slope instability in mountainous and cryospheric terrain. The objective of this study is to identify slow-moving la

Alaska's climate sensitive Yukon-Kuskokwim Delta supports seven million Arctic-breeding shorebirds, including the majority of six North American populations

Baseline information about declining North American shorebird populations is essential to determine the effects of global warming at low-lying coastal areas of the Arctic and subarctic, where numerous taxa breed, and to assess population recovery throughout their range. We estimated population sizes on the Yukon-Kuskokwim Delta in western Alaska on the eastern edge of the Bering Sea. We conducted

How to handle glacier area change in geodetic mass balance

Innovations in geodesy enable widespread analysis of glacier surface elevation change and geodetic mass balance. However, coincident glacier area data are less widely available, causing inconsistent handling of glacier area change. Here we quantify the bias introduced into meters water equivalent (m w.e.) specific geodetic mass balance results when using a fixed, maximum glacier area, and illustra

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...

Proportion of time that Pacific Flyway geese are at risk of wind-turbine strikes during transoceanic migrations

This tool shows the proportion of goose locations expected to be in or below a user-specified rotor-swept zone based on expected goose flight altitudes. Predictions were generated as detailed in the accompanying paper (citation below). The output assumes that geese are within an offshore windfarm footprint under mean conditions (daylight, light winds, 8-14°C, little precipitation, no fog, and...
