The dataset consists of geospatial files depicting the estimated June-to-November distribution of walrus foraging and occupancy during a four year period of sparse sea ice cover above the Chukchi...
-
This dataset is derived from images from a variety of Earth observing satellite imagery sources collected at known walrus coastal haulouts in Alaska and Chukotka, Russia. Earth observing imagery...
-
These data were used to evaluate effects of vessel exposure on Pacific walrus (Odobenus rosmarus divergens) behaviors. We obtained >120,000 hours of location and behavior (foraging, in-water...
-
An animal's energetic costs are dependent on the amount of time it allocates to various behavioral activities. For Arctic pinnipeds, the time allocated to active and resting behaviors could change...
-
This dataset consists of a complete set of audio recordings collected near a large walrus haulout at Point Lay, Alaska, during September of 2024. The recordings were collected using the Song Meter...

This dataset provides walrus counts in 10 m by 10 m square grid cells randomly selected from a standard set of grid cells established for the study area and that intersected with previously...
-
This dataset provides walrus haulout group outlines, systematic grids cast over the outlines, and digitized points at the centroids of the individual walruses identified inside a randomly selected...
-
This dataset contains lab-measured percent lipid and fatty acid composition data from Pacific walruses harvested in waters near Saint Lawrence Island. Each row indicates data from a single layer...
