USGS scientist measuring for suspected alopecia
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.
