Antarctic Coastal Benthic Habitats and Seafloor Geomorphology

Seafloor geomorphology and benthic habitat data for the Vestfold Hills coastal region in Antarctica. The dataset includes high-resolution multibeam data and bathymetry derived from multispectral satellite imagery, used to understand the distribution of macroalgae and invertebrate communities. It was presented at the 2023 POLAR 2018 conference and is hosted by the Australian Ocean Data Network.

Use Cases

• Mapping the spatial extent of vulnerable invertebrate-dominated ecosystems based on seafloor geomorphology.
• Identifying potential macroalgae habitat based on bathymetry and substrate data.
• Monitoring regime shifts from invertebrate to macroalgae communities based on changes in sea ice extent and light availability.
• Guiding biological field studies to assess ecosystem changes using the provided physical habitat framework.

Strengths

• Integrates high-resolution multibeam data with satellite-derived bathymetry to fill data gaps.
• Focuses on a specific, ecologically sensitive Antarctic coastal region (Vestfold Hills).
• Links physical seafloor data to biological concepts of ecosystem vulnerability and regime shifts.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; last metadata update was 2026-06-16.
