Campbell Island/Motu Ihupuku hosts a dataset of New Zealand sea lion movement and dive behavior. It contains data from 25 individuals across various age and sex classes, collected via satellite telemetry tags recording dive depth, duration, and location. The dataset was last updated on 2026-04-28 and is provided by the Australian Ocean Data Network.
Use Cases
- Modeling habitat use differences between age and sex classes based on the described behavioral variations.
- Analyzing diurnal patterns in diving behavior based on the time-of-day variable mentioned in the study.
- Assessing fisheries interaction risk by examining the proportion of benthic versus pelagic diving described for different groups.
- Comparing dive effort and duration between populations, such as the noted differences with sea lions at the Auckland Islands.
Strengths
- Data covers 25 individual sea lions from a range of age and sex classes, enabling comparative analysis.
- Includes multiple recorded variables: dive depth, duration, and geographic location.
- Study design explicitly tests hypotheses related to age, sex, time of day, and water depth, suggesting a structured research context.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for large-scale modeling.
- Description metadata is limited; actual data quality requires manual inspection after download.
