Seabed morphology and geomorphology of the Beagle Marine Park, south-eastern Australia - Version 1
<div>This data product contains geospatial seabed morphology and geomorphology information for the Beagle Marine Park and is intended for use by marine park managers, regulators, the general public and other stakeholders. A nationally consistent two-part (two-step) seabed geomorphology classification system was used to map and classify the distribution of key seabed features. </div><div><br></div><div>In step 1, semi-automated GIS mapping tools (GA-SaMMT; Huang et al., 2022; eCat Record 146832) were applied to bathymetry digital elevation models (DEM) in a GIS environment (ESRI ArcGIS Pro) to map polygon extents (topographic high, low, and planar) and quantitatively characterise their geometries. The geometric attributes were then used to classify each shape into discrete Morphology Feature types (Part 1: Dove et al., 2020; eCat Record 144305). In step 2, the seabed geomorphology was interpreted by applying additional datasets and domain knowledge to inform their geomorphic characterisation (Part 2: 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.</div><div><br></div><div>The Beagle Marine Park seabed morphology and geomorphology features were informed by a post survey report (Barrett et al., 2021). Seabed units were classified at multiple resolutions that were informed by the underlying bathymetry: </div><div><br></div><div>· A broad scale layer represents features that were derived from a 30 m horizontal resolution compilation DEM (Beaman et al 2022; eCat Record 147043). </div><div>· A series of medium and fine scale feature layers were derived from individual 1 m horizontal resolution DEMs (Nichol et al., 2019; eCat Record 130301). </div><div><br></div><div>The data product and application schema are fully described in the accompanying Data Product Specification. </div><div><br></div><div><em>Barrett, N, Monk, J., Nichol, S., Falster, G., Carroll, A., Siwabessy, J., Deane, A., Nanson, R., Picard, K., Dando, N., Hulls, J., and Evans, H.

- Purpose
-
This product provides users with information to understand the geodiversity of seabed features and substrates that characterise the Beagle Marine Park. It can be used to inform benthic habitat mapping and to better predict and understand biodiversity distributions. The product contributes to a nationally consistent seabed morphology and geomorphology mapping schema that can be implemented to inform other regional and national seabed data products.

<div>Underlying source bathymetric data were obtained from Nichol et al (2019) and Beaman (2022). </div><div><br></div><div>The data layers were produced by applying semi-automated mapping tools to bathymetry digital elevation models (DEMs) in a GIS environment (ESRI ArcGIS Pro) using a two-step approach. </div><div><br></div><div>In step 1, seabed morphology features were defined by generating polygons around topographic high, low, and planar features using the TPI (topographic position index) tool in GA-SaMMT (Geoscience Australia semi-automated morphology mapping tools) (Huang et al., 2022). Where appropriate, manual editing was also employed to modify the polygon boundaries of some features. Features were then classified by computing a set of quantitative geometric attributes and applying published Morphology Features glossary terms (Dove et al., 2020) using the GA-SaMMT. It should be noted that features of a certain size threshold or height (determined by the horizontal and vertical resolution of the underlying bathymetry grid) may not be captured by the semi-automated mapping tools. In addition, features that fall outside of the optimal user-defined parameters for the input data are not captured in the output. </div><div><br></div><div>In step 2, seabed geomorphology was interpreted by applying additional datasets and domain knowledge to inform the geomorphic characterisation of the seabed following Nanson et al., (2023). Where available, additional datasets include backscatter intensity data, seabed imagery (AUV and ROV), seabed samples, sub-bottom profiles and survey reports. Where a geomorphology classification has not been attributed, the following notation was applied:</div><div>NA: Classification at this level is not appropriate/applicable to the Setting/Process, or level of detail is out of scope and has not been attempted;</div><div>Unknown: There is insufficient data available to determine a geomorphology classification for a mapped Morphology Feature.</div><div><br></div><div>A full list of GIS layers that comprise this data product, and their descriptions, is included in the accompanying Data Product Specification.</div>
