Cape Darnley Bathymetry Compilation for East Antarctica

A new bathymetry compilation for the Cape Darnley region in East Antarctica, presented at the 2023 POLAR 2018 A SCAR & IASC Conference. The dataset was compiled by the Australian Ocean Data Network from single beam and multibeam data collected over several decades by multiple marine science voyages. It provides the first detailed bathymetric representation of the region, improving upon previous models.

Use Cases

• Modeling Antarctic Bottom Water transport pathways based on detailed shelf and slope morphology
• Understanding past glacial dynamics through geomorphic interpretation of the bathymetry
• Improving oceanographic and ecosystem models constrained by the new bathymetric data
• Studying contemporary seafloor processes in the Cape Darnley polynya region

Strengths

• First detailed bathymetry compilation for the Cape Darnley region
• Integrates data from multiple marine science voyages over several decades
• Enables visualization of shelf and slope morphology in unprecedented detail

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count and dataset scale are unknown, which may limit suitability assessment
