How you can help scientists track Arctic walrus populations from space

A new program from the British Antarctic Survey and World Wildlife Fund aims to enlist volunteers to identify Atlantic and Laptev walruses from satellite photos.

The walruses that live in the Atlantic portion of the Arctic Ocean and in Russia’s Laptev Sea are elusive and mysterious. Their habitat is remote, they spend a lot of time underwater, they ride on ice floes that can drift long distances and when they do go on land, they crowd tightly together. All that makes counting them difficult.
