These data are .csv files of tagged sea otter re-sighting locations (henceforth, resights) collected in the field using a combination of VHF radio telemetry and direct observation using high powered (80x) telescopes. Sea otters were tracked by shore or boat-based observers from the date of tagging until the time of radio battery failure, the animal’s death, or the end of the project, whichever comes first. The frequency of re-sighting was opportunistic, depending on logistical factors such as coastal access, but generally ranged from daily to weekly. Location coordinates are reported latitude and longitude as well as X and Y coordinates in the projection/datum California Teale-Albers NAD 1927. The file contains...

The current study was designed to provide critical information for resource managers (specifically the Bureau of Ocean Energy Management, henceforth BOEM, and the U.S. Fish and Wildlife Service, henceforth USFWS) about the spatial ecology, population status, and potential population threats to sea otters in Santa Barbara Channel, with particular reference to exposure to manmade structures and sources of oil and natural gas. Our four primary research objectives were: 1. Determine the extent of movements and spatial use patterns by sea otters along the southern California coast 2. Identify important sea otter resting and foraging areas adjacent to manmade structures 3. Assess sea otter distribution, behavior and...

These data are .csv files of capture data from tagged sea otters in the Santa Barbara Channel Study. Sea otters were captured using highly specialized techniques employed by a team a rebreather divers and were processed by a shore team and veterinary crew at a mobile vet lab. Overall health assessments and morphometric data were collected, and the otters received colored flipper tags (for visual identification in the field) as well as VHF radio transmitter implants (for locating and "re-sighting" individuals) and time-depth recorder instruments (for archival logging of dive records and core body temperature for individual sea otters). Fields include an individual otter identification number, capture date, general...
