California Current Ecosystems Program
Project
Completed
2016
The National Marine Mammal Laboratories' California Current Ecosystem Program (AFSC/NOAA) initiated a long-term marking program of California sea lions (Zalophus californianus). This dataset contains initial capture and marking data for California sea lion 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 natality rates.
The California sea lion natality dataset is used to estimate natality rates for marked California sea lions that can then be used in population models for stock status and Optimum Sustainable Population (OSP) determination.

Microsoft Access database for data storage and Microsoft Excel for data processing in the field.
Data include females of reproductive age (4 years old or older) for the 1987-2001 cohorts and resights for these animals from May through August each year, 1991-2008.
Initial capture data were recorded in the field on datasheets and then entered into a Microsoft Excel spreadsheet where they were error checked and then imported into the Microsoft Access database.
Prior to 2001, data were entered onto datasheets or in data books and transcribed each evening into a database. After 2001, sightings of branded or tagged animals were entered directly into Microsoft Excel spreadsheet with error checking code while observers were in the field. Sightings of brands or tags that were flagged as not existing in the database, wrong sex identification for an animal, or had not been seen in more than two years were photographed for later confirmation. Data were checked for duplicates, spelling errors, and incorrect field assignments each evening and before being uploaded into the database.

Up to 300, 3-month-old female 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 pup or not) 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. An important caveat to using the data to estimate natality of sea lions is that positive identification of reproductive status is difficult and models that allow for estimation of status uncertainty must be used.
