Tracking Polar Bears by Satellite

The USGS Alaska Science Center uses the latest technology in satellite radio-tracking to fill key information gaps on how polar bears use both the sea ice and land. Adult female polar bears are captured, fitted with satellite telemetry collars, and followed throughout their annual range. In collaboration with the U.S. Fish and Wildlife Service we are also experimenting with glue-on and ear tag satellite transmitters, which can be deployed on adult male bears and younger, still-growing bears.

Check back monthly for up-to-date movements of the satellite-tagged polar bears

Movements of 5 satellite-tagged polar bears for the month of July 2018

Movements of 5 satellite-tagged polar bears for the month of July, 2018. These bears received satellite eartag transmitters in 2018 on the spring-time sea ice of the southern Beaufort Sea. Polar bear satellite telemetry data are shown with AMSR2 remotely-sensed ice coverage for 31 July, 2018. AMSR2 data are made available by the University of Bremen ( The land cover is made available by Natural Earth ( Click on the above image to enlarge.
