NOAA_NCEI provides capture and resight data for over 1500 male California sea lions (Zalophus californianus) in Washington State. The dataset includes physical measurements from captures and subsequent resightings from California to Vancouver Island, Canada. Data collection occurred from February 15, 1989, to June 1, 2006.
Use Cases
- Analyze individual growth patterns by tracking changes in weight, length, and girth measurements across multiple capture events.
- Model sea lion movement and site fidelity using resight location data collected from California to Vancouver Island.
- Compare physical characteristics like weight and girth between California sea lions and the opportunistic Steller sea lion captures included in the dataset.
- Study population demographics and survival rates using capture and recapture (resight) records spanning 17 years.
Strengths
- Over 1500 individual male California sea lions captured
- Data collection spans a 17-year period from 1989 to 2006
- Includes multiple physical measurements per capture: weight, length, and girth
Limitations
- Dataset is limited to male California sea lions, excluding females and pups
- Data is over 15 years old, with the last update in June 2006
- Geographic coverage for resights is broad but dependent on opportunistic observer reports
