USGS is flying drones for science, small uncrewed areal systems (sUAS), to surveys walruses when they rest on shore. The sUAS makes minimal sound due it is broad wing and is flown high above the walrus herds to enables survey data collection with minimal risk to walruses.

Two adult walrus carcasses on the beach observed during the summer after a large group of walruses had rested on shore.  USGS is collaborating with the North Slope Borough Department of Wildlife Management to screen walruses for wildlife diseases and algal toxins.  The University of Alaska Fairbanks is collaborating with USGS to validate drone survey metho

This is a community flyer for distribution in Point Lay, Alaska, to alert community members of USGS activities in the area. A collaborative team of USGS, the North Slope Borough, University of Alaska Fairbanks, and Point Lay residents will assist in surveys of walrus carcasses at a remote coastal haulout that has been used by hundreds of thousands of walruses e

Skilak Lake, Alaska. A team of USGS scientists, in collaboration with partners from the Woods Hole Oceanographic Institution Ocean Bottom Seismic Instrument Center, are aiming to create a record of past earthquakes from Skilak Lake on the Kenai Peninsula of Alaska.

In May 2024, they deployed two seismographs on the bottom of the lake and eight seismographs on land around the lake. Each instrument will collect data there for about 1 year.
