New Zealand Sea Lion Movement and Dive Data from Campbell Island

Loaded with satellite telemetry data from 25 New Zealand sea lions of various age and sex classes from Campbell Island/Motu Ihupuku. It records dive depth, duration, and location to analyze behavioral differences related to age, sex, time of day, and water depth.

Use Cases

• Analyze dive depth and duration variations across different age and sex classes of sea lions.
• Model movement patterns and habitat use (benthic vs. pelagic) based on location data from satellite tags.
• Investigate correlations between time of day and dive behavior metrics like depth and duration.
• Assess risk of fisheries interaction by examining the proportion of benthic versus pelagic diving behavior.

Strengths

• Data originates from 25 instrumented sea lions, providing individual-level tracking.
• Includes multiple behavioral metrics: dive depth, duration, and location.
• Explicitly compares behavior across age/sex classes, enabling demographic analysis.

Limitations

• Sample size of 25 animals may limit statistical power for some subgroup analyses.
• Specific column names and data structure are not detailed in the provided input.
• Data freshness is unclear as the last update date is far in the future (2026).
