Airborne scanning LiDAR data was collected during the Sea Ice Physics and Ecosystems eXperiment (SIPEX) in early Spring 2007. Surveys were flown over sea ice between 110-130 degrees E longitude as part of Australian Antarctic science project 2901. The data was contributed by the AU_AADC organization.
Use Cases
- Validate satellite altimetry and polarimetric SAR data using LiDAR-derived sea ice elevation profiles.
- Analyze spatial variability in snow cover thickness over scales from meters to hundreds of kilometers.
- Determine sea ice drift characteristics and internal stress using repeated LiDAR survey tracks.
- Investigate relationships between physical sea ice environment and Southern Ocean ecosystem structure.
- Provide ground-truthing for existing and future satellite missions by comparing LiDAR measurements with satellite-tracked buoy and ice core data.
Strengths
- Data collected during a dedicated multi-disciplinary Antarctic sea ice experiment (SIPEX).
- Surveys cover a defined longitudinal region (110-130 degrees E) for spatial analysis.
- Intended for direct comparison with satellite-tracked buoys, ice cores, and drilled measurements.
Limitations
- Data is from a single campaign in 2007, limiting temporal analysis of trends.
- Specific sample size, row count, and column details are unknown.
- Geographic coverage is restricted to a specific Antarctic sector.
