2002 ice radar soundings collected by aircraft around Gillock Island, Antarctica. The dataset contains ASCII records of latitude and longitude coordinates extracted from 150 MHz radar data. It was gathered by the Australian Antarctic Division's Science and Technical Support group as part of the Australian Antarctica and Southern Ocean Profiling Project (AASOPP).
Use Cases
- Map the grounding zone boundary between the ice shelf and Gillock Island using the Latitude and Longitude coordinates.
- Analyze flight path patterns and spatial coverage of the aerial survey from the Time (UTC) and geospatial records.
- Support continental mapping projects for the Australian Antarctic Territory by integrating these geospatial soundings with other survey data.
Strengths
- Data focuses on a specific, scientifically critical area: the grounding zone near Gillock Island.
- Contains precise geospatial coordinates (Latitude, Longitude) and timestamps (Time (UTC)) for each radar sounding.
Limitations
- Unknown total row count and dataset size.
- Data is from a single year (2002) and may not reflect current ice conditions.
- Limited to ASCII extracted coordinates; the original binary radar data is not included.
