USGS flying drone
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
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.

Community Flyer for USGS Walrus Carcass Surveys
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

Male McKay's Bunting Foraging on Snow
The McKay's Bunting (Plectrophenax hyperboreus) is endemic to the Bering Sea Region and only breeds on St. Matthew Island. Designated as a species of high conservation concern due to its small population size, surveys show that the species has continued to decline since the initial survey effort in 2003.

The 1964 Tsunami in Valdez, Alaska
This is a remarkable film of the underwater landslide and tsunami at Valdez, Alaska, taken during the 1964 Great Alaska earthquake.
It has never been seen before in its correct sequence. There is no other film that we are aware of that shows the formation of a large submarine landslide.
