The survey was undertaken as a collaboration between the Australian Institute of Marine Science (AIMS) and GA. The purpose was to acquire geophysical and biophysical data on shallow (less then 100m water depth) seabed environments within two targeted areas in the Petrel Sub-basin to support investigation for CO2 storage potential in these areas. This dataset comprises an interpreted geomorphic map. Interpreted local-scale geomorphic maps were produced for each survey area in the Petrel Sub-basin using multibeam bathymetry and backscatter grids at 2 m resolution and bathymetric derivatives (e.g. slope; 1-m contours). Five geomorphic units; bank, plain, ridge, terrace and valley, were identified and mapped using definitions suitable for interpretation at the local scale (nominally 1:10 000). Maps and polygons were manual digitised in ArcGIS using the spatial analyst and 3D analyst toolboxes. {"type": "Polygon", "coordinates": [[[128.76996, -12.90414], [129.32719, -12.90414], [129.32719, -12.30465], [128.76996, -12.30465], [128.76996, -12.90414]]]} 128.76996 129.32719 -12.90414 -12.30465 Benthic geomorphic habitat Benthic habitat GIS dataset Marine Geoscience geomorphology marine environmental baselines SHAPE-ZIP documentDigital DATA ACCESS - This OGC WFS service returns the data (Petrel Sub-Basin interpreted geomorphology) in Shapefile format.
