NOAA_NCEI provides a dataset on hookworm disease mortality in California sea lion and northern fur seal pups. It contains counts of hookworms by sex found in the intestines of dead pups. Data were collected at haulouts and rookeries in California from July 1996 to January 2003.
Use Cases
- Analyze hookworm intensity by sex (male/female worm counts) across host species.
- Model seasonal or annual trends in parasite burden using collection dates from 1996-2003.
- Compare infection levels between California sea lion and northern fur seal host species.
- Correlate hookworm counts with mortality events at specific California haulout/rookery sites.
Strengths
- Data covers a multi-year time range from 1996 to 2003.
- Includes counts disaggregated by parasite sex for two distinct pinniped species.
- Focuses on a specific cause of mortality (hookworm disease) with clear scope.
Limitations
- Sample size (number of examined pups) is unknown.
- No column details or raw data samples are available for inspection.
- Data is temporally stale, with the last update in January 2003.
