Walrus Research
The USGS Alaska Science Center conducts long-term research on the Pacific walrus to provide scientific information to Department of Interior management agencies and Alaska Native co-management partners. In addition, the USGS Pacific walrus research program collaborates with the U.S. Fish and Wildlife Service (USFWS) and the State of Alaska’s Department of Fish and Game and Alaska Native co...
Tracking Data for Pacific Walrus (Odobenus rosmarus divergens)
Available here are tracking data of Pacific walrus, a marine mammal that ranges between the Alaska Peninsula, up through the Bering and Chukchi seas, and over to Russia. These data were collected from animals marked in the northern Bering and Chuckchi sea to understand seasonal movement patterns, use of coastal haulouts in northwestern Alaska, and determine estimates of abundance in autumn.

Q&A: New Drone-Based Method Helps Monitor Walrus Health
Innovative drone technology provides critical insights into the body condition and health of Pacific walruses in a changing Arctic.
Q&A: Estimates of Abundance for Pacific Walrus
The Pacific walrus ranges across the Bering and Chukchi seas during the year. This wide geographic distribution makes it difficult to estimate Pacific walrus population abundance. However, recent technological advances in genetics and drone imagery have generated precise regional and range-wide abundance estimates.
