Pacific Walrus Coastal Haulouts: Outlines and Herd Densities from Drone Imagery Dataset 2017-2019.

ABSTRACT: Data were generated through repeatable methods involving the visual interpretation of aerial images captured over Pacific walrus coastal haulouts using various models of DJI-manufactured drones. Outlines of walrus herds are presented for 185 surveys conducted in 2017, 2018, and 2019. Digitized centroids of walrus on haulouts are included for 88 aerial surveys; sampling grids are included for 77 aerial surveys conducted in 2018 and 2019.
