A polar bear is being subjected to the enhanced sampling protocol for suspected alopecic bears. In the photo, we're using the tape measure to demonstrate the size of the area of hair loss on the neck. This photo was taken on the sea ice north of Utqiagvik, Alaska.

Large numbers of walruses came ashore to rest near the community of Point Lay, Alaska when sea ice had dissipated from their offshore foraging grounds in the eastern Chukchi Sea during late August through October of 2011. Walruses in these groups cycled between this coastal resting area and their foraging grounds, both near-shore and offshore.
