Walrus Watch: Migration map
Tagged walrus
Scientists have tagged eight walruses
Scientists have used satellite tags to track walruses in west Greenland in an effort to understand the creatures' migration habits.

The whereabouts of the walruses have been plotted on the map below using data received from the Danish-Greenlandic research team.

MIGRATION MAP
Map
Walrus 1: Male, 4-5 years
Walrus 2: Female, 10-12 years - has yearling calf in tow
Walrus 3: Anomalous data point
Walrus 4: Male, 5-6 years
Walrus 5: Male, 18-20 years
Walrus 6: Female, 5-6 years
Walrus 7: Male, 5-7 years
(No data received from a tagged female and her son)


HOW THE PROJECT WORKS

  • Researchers attached eight satellite tags to walruses in west Greenland

  • The satellite tags transmit location coordinates to the scientists via the Argos satellite system

  • Data appears on this map, linked to from our stories, showing the animals' progress
  • Walrus 2's transmitter functioned for several months, revealing the beast's summer migration

The tagging study was run by the Greenland Institute of Natural Resources, in cooperation with the Danish National Environmental Research Institute and the Technical University of Denmark.
