This dataset consists of observations made of foraging sea otters (Enhydra lutris). Observers used Questar field model spotting scopes and binoculars to identify prey. Date, local time, dive duration, success, prey type, prey size, prey number, handling time and surface time were all recorded. Sites are in Alaska and include locations in Kachemak Bay, Katmai National Park and Preserve, Kenai Fjords National Park and Prince William Sound. The data in this file were collected from 2012—2024.
