Antarctic Coastal Benthic Habitats with Seafloor Geomorphology and Sea Ice Data

High-resolution multibeam and satellite-derived bathymetry data map shallow-water benthic ecosystems in the Vestfold Hills, Antarctica. The dataset provides a physical framework for understanding habitat distribution and vulnerability to sea ice changes. Geoscience Australia Data presented this work at the 2023 POLAR 2018 A SCAR & IASC Conference.

Use Cases

• Modeling the spatial extent of macroalgae and invertebrate communities based on seafloor geomorphology.
• Assessing ecosystem vulnerability to sea ice retreat using bathymetry data from areas under ice.
• Identifying potential habitat for macroalgae colonization based on substrate type and light availability.
• Establishing a baseline for monitoring future benthic community shifts in Antarctic coastal waters.

Strengths

• Integrates high-resolution multibeam data with satellite-derived bathymetry to fill data gaps.
• Focuses on the ecologically significant Vestfold Hills region in Antarctica.
• Directly supports research on climate-driven regime shifts, citing a 2013 study (Clark et al.).

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 may reflect geographic bias inherent to the specific Antarctic study area.
