Antarctic Ice Radar Soundings from 2002 Priority Flights

2002 ice radar soundings collected over the Amery Ice Shelf grounding zone near Gillock Island. The dataset contains ASCII records of latitude, longitude, and UTC time extracted from 150 MHz radar data collected by aircraft. 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 line position between the Amery Ice Shelf and Gillock Island using the latitude and longitude coordinates.
• Analyze flight path patterns and temporal sequencing of data collection using the Time (UTC) field.
• Correlate radar sounding locations from this dataset with other geophysical or satellite datasets using the provided latitude and longitude as join keys.

Strengths

• Data covers a scientifically critical region: the grounding zone of the Amery Ice Shelf.
• Specific temporal coverage from priority flights conducted in 2002.

Limitations

• Unknown total row count and column details beyond latitude, longitude, and time.
• Data is from a single year (2002) and may not reflect current conditions.
• Lacks accompanying radar echo strength or ice thickness measurements in the described ASCII records.
