Cape Darnley Bathymetry Compilation at 100-Meter Resolution

A 100-meter resolution bathymetric grid compiles three decades of scientific data from 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 high-resolution grid improves previous seafloor representations and visualizes morphology in unprecedented detail.

Use Cases

• Numerical modelling 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 geological and biological habitat studies.

Strengths

• 100-meter grid resolution enables detailed visualization.
• Integrates multiple high-resolution data sources from the last 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 dataset size are unknown, which may limit suitability assessment.
