East Antarctic Marine Protected Area Bathymetry at 100m Resolution

Australian Antarctic Division compiled this bathymetry dataset to support a proposal for seven Marine Protected Areas in East Antarctica. It integrates multibeam and singlebeam acoustic data, processed and gridded to a 100-meter resolution. The data and technical report were made available by Geoscience Australia in December 2010.

Use Cases

• Modeling seafloor habitat suitability by analyzing 100m-resolution bathymetric depth values.
• Planning marine protected area boundaries using gridded depth data to identify key seabed features.
• Conducting geospatial analysis of seafloor morphology by processing the provided ESRI rasters or GeoTIFFs.

Strengths

• Data compiled from all available multibeam and singlebeam acoustic sources at the time of creation.
• Processed bathymetry gridded to a consistent 100-meter spatial resolution.
• Data exported in multiple formats (xyz, ESRI raster, GeoTIFF, CARIS) for different analytical tools.

Limitations

• Dataset is temporally stale, with a last update in 2010, potentially missing newer surveys.
• Spatial coverage is limited to seven proposed Marine Protected Areas in East Antarctica.
• Specific row counts, file sizes, and original data collection dates are unknown.
