Nineteen seasons of colony-based data from Ross Island track Adélie penguin adaptation to expanding sea ice. This four-year NASA project analyzes migration, survival, and reproduction for known-age individuals. Research aims to understand carry-over effects from winter ice conditions to annual breeding success.
Use Cases
- Model penguin survival rates from migration behavior and winter sea ice condition data.
- Analyze carry-over effects on subsequent reproduction using individual age and breeding history records.
- Assess population change by correlating nesting habitat data with individual quality metrics.
- Study the interplay between extrinsic environmental factors and intrinsic individual factors over multi-year lifetimes.
Strengths
- Data spans 19 years of colony observations at Ross Island.
- Includes tracking of individually marked, known-age penguins across their lifecycle.
Limitations
- Specific row counts, column details, and sample data are unavailable.
- Geographic focus is limited to the Ross Sea region, limiting generalizability.
Provenance
- Source
- NASA Earthdata via AMD_USAPDC.
- Collection Method
- Colony-based data collection and tracking of individually marked penguins.
- Time Range
- At least 19 seasons, plus a 4-year project extension.
- Freshness
- null
- Geography
- Ross Island and the Ross Sea region, Antarctica.
