Filtered Antarctic Predator Tracking Data with State-Space Model Interpolation

Tracking data from the 1990s onward, compiled by the Scientific Committee on Antarctic Research (SCAR) project RAATD. It consolidates movement records for 17 species of Antarctic meso- and top-predators, including birds and marine mammals. The provided data files contain filtered position estimates processed with a state-space model for regular time intervals.

Use Cases

• Modeling species-specific movement patterns using interpolated position estimates from CSV files.
• Assessing model fit and quality control for individual animal tracks via the provided PDF diagnostic reports.
• Analyzing deployment metadata (e.g., species, location, time) from the master CSV file to study tracking effort.
• Reproducing or extending the state-space filtering analysis using the fitted model objects stored in RDS files.

Strengths

• Consolidated data from a large number of research groups working since the 1990s.
• Provides processed data for 17 distinct predator species.
• Includes model objects, diagnostics, and interpolated positions for each species.

Limitations

• Specific row counts, sample sizes, and temporal ranges for each species are not detailed in the provided metadata.
• Data is from 2016 and may not include recent tracking studies.
• Requires R software to fully utilize the RDS model objects.
