Pacific Walrus Behavior Data and Associated Chukchi Sea Ice Observations and Projections for use with Bioenergetics Models to Forecast Walrus Body Condition
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...
