Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This data product contains geospatial seabed morphology and geomorphology information for a subset area of Zeehan Marine Park. These seabed feature map layers are intended for use by marine park managers, regulators, the general public and other stakeholders. A nationally consistent seabed geomorphology classification scheme was used to map and classify the distribution of key seabed features. </SPAN></P><P><SPAN>Semi-automated GIS mapping tools (GA-SaMMT; Huang et al., 2022; eCat Record 146832) were applied to a bathymetry digital elevation model (DEM) in a GIS environment (ESRI ArcGIS Pro) to map polygon extents (topographic high, low, and planar) and to quantitatively characterise polygon geometries. Geometric attributes were then used to classify each shape into discrete Morphology Feature types (Dove et al., 2020; eCat Record 144305). Seabed geomorphology features were interpreted by applying additional datasets and domain knowledge to inform their geomorphic characterisation (Nanson et al., 2023; eCat Record 147818). Where available, backscatter intensity, seabed imagery, seabed sediment samples and sub-bottom profiles supplemented the bathymetry DEM and morphology classifications to inform the geomorphic interpretations.</SPAN></P><P><SPAN>The Zeehan Marine Park seabed morphology and geomorphology maps were derived from a 2 m horizontal resolution bathymetry DEM compiled from a multibeam survey undertaken for Parks Australia by the University of Tasmania.</SPAN></P><P><SPAN>The data product and classification schema are fully described in the accompanying Data Product Specification. </SPAN></P></DIV></DIV></DIV>
