This is a graphical abstract for a publication by the USGS that evaluates satellite imagery for monitoring large Pacific walrus haulouts in northwestern Alaska.
This is a nation-wide collaborative program, supported by the USGS Ecosystems Mission Area, through which USGS and U.S. Fish and Wildlife Service staff address priority research needs identified by the U.S. Fish and Wildlife Service. On this page, we highlight research taking place in Alaska as part of this program.
Return to Ecosystems >> Collaborative Science for Priority Information Needs
U.S. Fish and Wildlife Service priorities change annually through this program. Results of past studies can be found under Data and Tools and Publications on this page.
For 2020-2023, the USGS Alaska Science Center is focusing on the following science needs identified by the U.S. Fish and Wildlife Service Alaska Region:
- Processing and publication of high-resolution coastal walrus haulout survey imagery
- Quantifying groundwater and aufeis and their contribution to surface water availability and habitat in the Arctic National Wildlife Refuge, Alaska
- Distribution and abundance of breeding waterbirds in relation to habitat type on the 1002 Area of the Arctic National Wildlife Refuge, Alaska
- Development of a population monitoring plan for the Southern Beaufort Sea polar bear subpopulation
- Assessing the population status of two rare taxa endemic to the central Bering Sea, Alaska: McKay's Bunting and Pribilof Rock Sandpiper
- Improved mapping of historical fire perimeters on Alaska National Wildlife Refuges
Below are other science projects associated with this project.
Q&A: Vessel Cruise for Estimates of Pacific Walrus Demography
Adult female and juvenile Pacific walruses reside in the northern Bering Sea and Chukchi Sea in the late spring and summer. In June of 2024, the U.S. Fish and Wildlife Service and the USGS will again conduct a walrus research cruise on the Research Vessel Norseman II. The cruise will depart from Nome, Alaska on May 31, 2024, and return to Nome on June 28, 2024. The research cruise will be...
Q&A: Improving Aerial Surveys of Geese in Alaska with Aerial Imagery
Thousands of geese gather at Izembek Lagoon in southwestern Alaska every fall where they “stage”, meaning that they rest and eat in preparation for migration to lower latitudes. Izembek Lagoon is especially important for Pacific brant geese, as the entire Pacific Flyway population is thought to use the lagoon in fall. This provides an opportunity to efficiently survey the population to track...
Winter Habitat of Juvenile Dolly Varden in the Canning River
In the Arctic, rivers often freeze all the way to the bottom each winter leaving fish with limited habitat where they can survive.

Caribou Tracks Along Alaska's Coast
This photograph shows caribou tracks on ice-wedge polygons near Garry Creek in Alaska. Coastal erosion along the Arctic coast is chronic, widespread and potentially accelerating, posing threats to infrastructure important for defense and energy purposes, natural shoreline habitats and nearby Native communities.
