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": [[[128.769964, -12.90414], [129.327193, -12.90414], [129.327193, -12.304648], [128.769964, -12.304648], [128.769964, -12.90414]]]} 128.769964 129.327193 -12.90414 -12.304648 GIS Dataset Marine Data Marine Geoscience Published_External geomorphology marine marine environmental baselines seabed Related Product documentDigital Related product: Petrel Sub-basin Marine Survey - Ecology / Underwater video footage and still images HTML Related Product documentDigital Related product: Petrel Sub-basin Marine Survey - Seabed Geochemistry / Porewater TCO2 and TCO2 flux HTML Related Product documentDigital Related product: Petrel Sub-basin Marine Survey - Seabed Geochemistry / Chlorins HTML Related Product documentDigital Related product: Petrel Sub-basin Marine Survey - Seabed Geochemistry / Chlorophyll abc and pheaophytin HTML Related Product documentDigital Related product: Petrel Sub-basin Marine Survey - High Resolution Backscatter Grids HTML Related Product documentDigital Related product: Petrel Sub-basin Marine Survey - Seabed Geochemistry / TOC, TN and carbon and nitrogen isotopes HTML Related Product documentDigital Related product: Petrel Sub-basin Marine Survey - Seabed Geochemistry / Sediment Oxygen Demand.
