Antarctic Coastal Benthic Habitat Mapping for Vulnerability Assessment

A study of shallow-water benthic ecosystems in the Vestfold Hills, Antarctic coastal region, using high-resolution multibeam and satellite-derived bathymetry data. The dataset, presented at the 2023 POLAR 2018 conference, provides a physical framework for understanding habitat distribution and vulnerability to sea ice changes. It is hosted by the Australian Ocean Data Network.

Use Cases

• Modeling benthic community distribution based on seafloor geomorphology and substrate type.
• Assessing ecosystem vulnerability to regime shifts from macroalgae to invertebrates based on sea ice cover.
• Identifying potential macroalgae habitat in very shallow areas using satellite-derived bathymetry.
• Establishing environmental baselines for monitoring future changes in Antarctic coastal waters.

Strengths

• Integrates high-resolution multibeam data with satellite-derived bathymetry to fill data gaps.
• Focuses on a specific, ecologically sensitive region: the Vestfold Hills coastal waters.
• Links physical habitat data (geomorphology, ice cover) to biological vulnerability concepts.

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.
• Data freshness should be verified; last metadata update was 2026 06 23.
