Tagging Walruses
Detailed Description
A transmitter tag (left) is being deployed by a USGS Wildlife Biologist (far right).
Transmitter tags are deployed on the back of walruses where their skin is thickest and where their data transmissions may be received from passing satellites. Tag deployment happens in the blink of an eye with the use of a crossbow and specialized arrow. These transmitter tags will provide the individuals location as well as data on hourly resting and foraging behaviors. Preliminary plots of tracked walruses and sea ice may be viewed online.
