17605 AFSC/NMML/CCEP: Natality rates of California sea lions at San Miguel Island, California during 1987-2008 Data Set Published / External 23110 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.

Publication describing methods and results of data analysis. 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. 30979 Entity 30980 Entity 30978 Entity gov.noaa.nmfs.inport:17605 SysAdmin InPortAdmin 2013-01-14T16:40:44 SysAdmin InPortAdmin 2026-03-04T19:17:25 2018-11-27 Alaska Fisheries Science Center AFSC 7600 Sand Point Way N.E., Building 4 Seattle WA 98115 USA https://www.afsc.noaa.gov 0700-1700 Pacific Time 1001 Public No No 2018-11-27 1 Year 2019-11-27 none California sea lions Kingdom Animalia Genus Zalophus Species californianus California sea lion ALIVE NA AFSC aliveid Primary key - has no meaning to data AFSC 1 453161002 pupyear Year pupped (if sighted Jan-May 20, this will be the year previous to sighting year) AFSC 87 2008 sitedate sighting date mm/dd/yy AFSC 198709200000 200812290000 code area on the site where sighted - not all sites have areas AFSC unknown sitecode site where sighted - island or unique coast areas AFSC unknown region numberical code for coastal regions AFSC 1 2777 lat latitude of sighting AFSC 28.32 55.7 longit longitude of sighting AFSC 0 133.8 brand brand number AFSC 2 84464 side location of brand on body AFSC unknown brandcheck verification of brand and side AFSC unknown brandcond condition of brand AFSC unknown tagnumber tag number AFSC unknown left tag on left flipper AFSC unknown right tag on right flipper AFSC unknown colortype color and type of flipper tag AFSC unknown adjsex sex AFSC unknown observer observer's initials AFSC unknown comments comments about sighting or animal AFSC unknown withpup reproductive status of females AFSC unknown pregnant reproductive status of females AFSC unknown Check observer check at sighting (added 2003) AFSC unknown Lastyr Number of years since last seen twice in a season (added 2003) AFSC 0 17 adj/sex sex and adjusted sex comparison at sighting (added 2003) AFSC unknown photos Photos taken at observation time Y=Yes, N=No, Blank=unknown AFSC unknown flipperobs Code for number of flippers observed when resighted. 0=none,1=1 flipper,2=both AFSC 0 2 ageclass Age class at sighting.
