    • AFSC/NMML/CCEP: Survival Rate of California sea lions at San Miguel Island, California from 1987-2009

    Metadata Updated: November 1, 2024

    The dataset contains initial capture and marking data for California sea lion (Zalophus californianus) pups at San Miguel Island, California and subsequent resighting of the marked animals throughout the time series. The data are used in mark-recapture analysis to estimate survival rates.

    Lineage Up to 500, 3-month-old California sea lion pups were branded on the left or right shoulder and tagged in the foreflippers each year at San Miguel Island, California. Each year thereafter, biologists used binoculars, spotting scopes, and cameras to resight animals at San Miguel Island, other Channel Islands, and at coastal haulouts along the California coast during the summer from May through August. The individual's brand and/or tag number, area sighted, age class, sex and reproductive status (e.g. with/without a pup) were recorded. Prior to 2001, data were entered onto datasheets or in data books and transcribed each evening into a database. After 2001, data were entered in the field into a computer tablet using Microsoft Excel with an error-checking program. These capture and resighting data can be used to construct capture/sighting histories that can then be used in mark-recapture analysis.
