Summary

This data release comprises 3 datasets used to develop forecasts of autumn body condition for adult female Pacific walruses in the Chukchi Sea during mid and late century time periods. The activity dataset contains daily telemetry records for 218 adult female walruses tracked for periods of 7 to 104 days during 2008-2014, in the Chukchi Sea. Records include the number of hours the walrus was in the water, number of hours the walrus was foraging, study area region where the walrus was located, depths of the foraging locations, and the proportion of the region covered by sea ice. The movement dataset contains telemetry records for 94 of these walruses, giving the dates they moved from one region to another, and the date of the beginning [...]

Purpose

Develop models of walrus activity and movement as functions of sea ice conditions, forecast future walrus activity and movement as functions of projected future sea ice conditions, and link to bioenergetics models to forecast autumn body condition for adult female Pacific walruses in the Chukchi Sea during mid and late century time periods.
