description:	This dataset comprises an interpreted geomorphic map for each survey area of the Petrel Sub-basin Survey (GA0335) 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. The dataset can be downloaded at the following URL http://www.ga.gov.au/metadata-gateway/metadata/record/81955.
