Requested Walrus Tracking Map
Over the last ten days we received transmissions from 23 walruses (2 male and 21 female). Five walruses are still in Russian waters, near Wrangel Island, and 1 is in coastal waters of northern Alaska near Harrison Bay and the Kogru River. The remaining 17 are located within, or near, the boundaries of Lease Area 193, of which 14 spent more than one day within the Hanna Shoal Walrus Use Area. The two males are still in the central Chukchi Sea.

In addition to the movement tracks of these walruses we mapped the boundary of Lease Area 193 (orange outline), Hanna Shoals (black outline based on the 40m isobaths), and the Hanna Shoal Walrus Use Area (green). Sea ice data are courtesy of the U.S. National Ice Center, dated 4 August 2014 (http://www.natice.noaa.gov/index.html). Funding for this project is provided by the Bureau of Ocean Energy Management (BOEM). Walruses were tagged in the Chukchi Sea from 1–23 June, 2014.
