Cape Darnley Bathymetric Compilation for East Antarctica at 100m Resolution

A high-resolution 100-meter bathymetry grid compiles three decades of scientific data for the Cape Darnley region in East Antarctica. The compilation, published in Antarctic Science in 2021, integrates single-beam, multibeam, and chart data from numerous institutions. This detailed seafloor morphology forms a baseline for oceanographic and glaciological modeling.

Use Cases

• Numerical modeling of ocean circulation based on detailed seafloor morphology.
• Reconstruction of palaeo-ice streams using high-resolution bathymetric data.
• Refinement of ice-sheet models with improved regional bathymetry.
• Visualization of seafloor features for biological and geological habitat studies.

Strengths

• High 100-meter grid resolution provides unprecedented detail for seafloor visualization.
• Integrates multiple data sources including high-resolution bathymetry datasets acquired over three decades.
• Constructed using a layered hierarchy approach based on data source quality.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Freshness should be verified; the record was last updated on 2026 05 14.
