Antarctic Ice Shelf Radar Soundings from 2002 Amery Survey

Ice radar soundings at 150 MHz were collected via aircraft over the Amery Ice Shelf near Gillock Island in 2002. The Australian Antarctic Division's Science and Technical Support group built the radar unit for the Australian Antarctica and Southern Ocean Profiling Project (AASOPP). Data includes ASCII records with time, latitude, and longitude coordinates.

Use Cases

• Map the grounding zone boundary between the Amery Ice Shelf and Gillock Island using latitude and longitude coordinates.
• Analyze flight path and temporal coverage of the survey using the Time (UTC) column alongside spatial records.
• Correlate subsurface ice structure from 150 MHz radar soundings with specific geographic positions defined by Latitude and Longitude.

Strengths

• Data targets a specific, scientifically critical region: the grounding zone near Gillock Island.
• Records include precise geospatial coordinates (Latitude, Longitude) and Time (UTC) for spatiotemporal analysis.

Limitations

• Exact row count, column details beyond core fields, and file size are unknown.
• Data is from a single survey in 2002, offering a historical snapshot but not temporal continuity.
• The dataset description lacks information on data density, sampling rate, or accompanying radar amplitude data.
