COLDEX Open Polar Radar: Airborne Radar Transects of Antarctic Ice

3 terabytes of raw airborne radar data were collected during the 2022/23 and 2023/24 Antarctic field seasons for the Center for Oldest Ice Exploration (COLDEX). The dataset includes processed radargrams in HDF5/Matlab and netCDF formats, as well as reprojected images in PNG/JPG formats, organized for non-expert access. Duncan A. Young is the author, and the data is hosted via the Texas Data Repository and the University of Kansas CReSIS data portal.

Use Cases

• Analyzing ice sheet stratigraphy and internal layers based on the described radargram imagery.
• Mapping subglacial topography and bedrock interfaces using the airborne radar transects.
• Investigating the continuity and age of ancient ice archives, a core goal of the COLDEX project mentioned in the description.
• Developing automated feature detection algorithms for radargram interpretation based on the provided image formats.

Strengths

• Includes 3 terabytes of raw data from two consecutive Antarctic field seasons (2022/23 and 2023/24).
• Data is organized for non-expert access with multiple processed formats (HDF5, netCDF, PNG, JPG).
• Has a clear authoritative provenance from the COLDEX Science and Technology Center and CReSIS.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and exact file sizes for processed formats are unknown, which may limit suitability assessment.
• The description metadata is limited to project context and access links; detailed data specifications require manual inspection.
