Lineage

The Australian Antarctic Division developed a proposal for the establishment of seven Marine Protected Areas (MPAs) located around east Antarctica for the purposes of marine ecosystem conservation. As detailed seafloor morphology is critical to understanding marine ecosystems, this bathymetry compilation for the proposed MPAs was compiled to support the AAD proposal. All bathymetry data available to Geoscience Australia at the time of compilation was used. This included multibeam and singlebeam acoustic data which was verified and processed to ensure the data was as accurate as possible. Processing included sound velocity corrections, navigation verification and the rejection of erroneous data points. Once processed, the data was gridded to 100m resolution and projected into suitable WGS84 UTM zones. The gridded data was exported into several formats to facilitate ease of use. The formats include xyz files, ESRI rasters, geoTIFs, CARISTM image files and soundings.
