This dataset comprises an interpreted geomorphic map for each survey area of Leveque Shelf MarineSurvey (GA0340) using multibeam bathymetry and backscatter grids at 2 m resolution and bathymetric derivatives (e.g. slope; 1-m contours). Seven geomorphic units; bank, dune, dune (trochoidal), mound, plain, terrace, valley and bedform fields 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.
