USGS scientists scan the ice for resting walruses
Detailed Description
Sarah Sonsthagen (left) drives a skiff as Tony Fischbach scans the ice for resting walruses to radio-tag. On an hourly basis, these instruments show whether the walrus is in the water, resting out of the water, or foraging at the seafloor. The radio tag will fall off after 3 to 12 weeks.
