Bathymetry Compilation for Cape Darnley, East Antarctica

A detailed bathymetry compilation for the Cape Darnley region in East Antarctica, presented at the 2023 POLAR 2018 conference. The dataset was created by compiling single beam and multibeam data from multiple marine science voyages over several decades, held by several institutes. It provides the first detailed insights into seafloor morphology and potential bottom water transport pathways.

Use Cases

• Modeling Antarctic Bottom Water transport pathways based on detailed shelf and slope morphology.
• Constraining oceanographic and ecosystem models with improved regional bathymetric data.
• Interpreting past glacial dynamics based on geomorphic features revealed by the bathymetry.
• Studying contemporary seafloor processes in a key polynya region.

Strengths

• First detailed bathymetry compilation for this specific region of East Antarctica.
• Integrates data from multiple marine science voyages over several decades.
• Enables visualization of shelf and slope morphology in unprecedented detail compared to previous representations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data quality is described as varying, as it was compiled from sources held by several institutes.
• Row count and dataset scale are unknown, which may limit suitability assessment.
