Subglacial Basin Topography and Faults from East Antarctica

East Antarctica subglacial basin data includes filtered bed elevation points and detected fault lines. The dataset contains MATLAB functions for estimating Euler poles and small circle centers, supporting the associated 2026 Nature Geoscience paper. It was authored by Egidio Armadillo and last updated in June 2026.

Use Cases

• Model rotational extension based on estimated Euler poles.
• Analyze subglacial basin morphology based on filtered bed elevation data.
• Map tectonic fault networks based on detected fault shapefiles.
• Validate geophysical models using provided MATLAB analysis functions.

Strengths

• Includes specific MATLAB functions (ep_estimate.m, error_ell_est_mc.m, estimate_small_circle_centre.m) for analysis.
• Contains geospatial data in multiple formats (XYZ text files, SHP shapefiles).
• Directly supports a peer-reviewed publication in Nature Geoscience.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 1.6 MB size suggests a relatively small spatial sample.
