Oceanic Shoals Commonwealth Marine Reserve (Timor Sea) Biodiversity Survey (GA0339/SOL5650) - Interpreted Geomorphic Map

The Oceanic Shoals survey (SOL5650, GA survey 339) was conducted on the R.V. Solander in collaboration with Geoscience Australia, the Australian Institute of Marine Science (AIMS), University of Western Australia and the Museum and Art Gallery of the Northern Territory between 12 September - 5 October, 2012. This dataset comprises an interpreted geomorphic map.

Interpreted local-scale geomorphic maps were produced for each survey area in the Oceanic Shoals Commonwealth Marine Reserve (CMR) using multibeam bathymetry and backscatter grids at 2 m resolution and bathymetric derivatives (e.g. slope; 1-m contours). Six geomorphic units; bank, depression, mound, plain, scarp and terrace 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.

For further information on the geomorphic mapping methods please refer to Appendix N of the post-survey report, published as Geoscience Australia Record 2013/38: Nichol, S.L., Howard, F.J.F., Kool, J., Stowar, M., Bouchet, P., Radke, L., Siwabessy, J., Przeslawski, R., Picard, K., Alvarez de Glasby, B., Colquhoun, J., Letessier, T. & Heyward, A. 2013.

海洋浅滩调查（SOL5650，GA调查339）于2012年9月12日至10月5日期间，由“索兰德号”（R.V. Solander）研究船执行，合作方包括澳大利亚地球科学局（Geoscience Australia）、澳大利亚海洋科学研究所（Australian Institute of Marine Science, AIMS）、西澳大利亚大学以及北领地博物馆与美术馆。
本数据集包含解译地貌图。
研究团队针对海洋浅滩英联邦海洋保护区（Commonwealth Marine Reserve, CMR）内的每个调查区域，采用分辨率为2米的多波束测深（multibeam bathymetry）与反向散射网格（backscatter grids）数据，以及水深衍生数据（如坡度、1米等高线），制作了解译局地尺度地貌图。本次研究识别并填绘了6类地貌单元：岸滩（bank）、洼地（depression）、丘体（mound）、平原（plain）、陡坎（scarp）与阶地（terrace），所用定义适配局地尺度解译需求（标称比例尺为1:10000）。所有地图与多边形均通过ArcGIS软件的空间分析（Spatial Analyst）与3D分析（3D Analyst）工具箱完成手动数字化。
