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.\nInterpreted 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.\nFor 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.

(GEOCAT #76658).本海洋浅滩调查（SOL5650、GA调查339）于2012年9月12日至10月5日期间，依托索兰德号科考船（R.V. Solander）开展，合作单位包括澳大利亚地质调查局（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。本数据集包含经解译的地貌图。 针对海洋浅滩联邦海洋保护区（Commonwealth Marine Reserve, CMR）内的各调查区域，研究团队利用分辨率为2米的多波束测深与后散射栅格数据，以及水深衍生数据（如坡度、1米等高线），生成了局地尺度的经解译地貌图。研究采用适配局地尺度解译的定义（标称比例尺1:10000），识别并绘制了6类地貌单元：岸堤、洼地、丘体、平原、陡崖与阶地。所有地图与多边形均通过ArcGIS的空间分析工具箱（Spatial Analyst）与三维分析工具箱（3D Analyst）完成手动数字化。 若需了解地貌制图方法的更多细节，请参阅调查报告附录N，该报告以《澳大利亚地质调查局报告2013/38》形式发布：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.与Heyward A.，2013年。《海洋浅滩联邦海洋保护区（帝汶海）生物多样性调查：GA0339/SOL5650调查报告》，报告编号2013/38，澳大利亚地质调查局，堪培拉。（GEOCAT #76658）
