Bathymetry grids of south east Tasmania Shelf

Geoscience Australia carried out marine surveys in southeast Tasmania in 2008 and 2009 (GA0315) to map seabed bathymetry and characterise benthic environments through observation of habitats using underwater towed video. Data was acquired using the Tasmania Aquaculture and Fisheries Institute (TAFI) Research Vessel Challenger. Bathymetric mapping was undertaken in seven survey areas, including: Freycinet Pensinula (83 sq km, east coast and shelf); Tasman Peninsula (117 sq km, east coast and shelf); Port Arthur and adjacent open coast (17 sq km); The Friars (41 sq km, south of Bruny Island); lower Huon River estuary (39 sq km); D Entrecastreaux Channel (7 sq km, at Tinderbox north of Bruny Island), and; Maria Island (3 sq km, western side). Video characterisations of the seabed concentrated on areas of bedrock reef and adjacent seabed in all mapped areas, except for D Entrecastreaux Channel and Maria Island.

The dataset contains 8 bathymetry grids produced from the processed EM3002 bathymetry data using the CARIS HIPS and SIPS software. Please see the metadata informaiton for detailed information.

澳大利亚地质调查局（Geoscience Australia）于2008年和2009年在塔斯马尼亚东南部开展了编号为GA0315的海洋调查，旨在通过水下拖曳视频（underwater towed video）观测生境，完成海底水深地形（seabed bathymetry）测绘并表征底栖环境（benthic environments）。本次调查依托塔斯马尼亚水产与渔业研究所（Tasmania Aquaculture and Fisheries Institute, TAFI）的“挑战者号”研究船完成数据采集。此次水深地形测绘共覆盖7个测区，分别为：菲辛内特半岛（Freycinet Peninsula，83平方公里，东海岸及陆架区）、塔斯曼半岛（Tasman Peninsula，117平方公里，东海岸及陆架区）、亚瑟港及邻近开阔海岸（17平方公里）、布尼岛以南的弗里亚尔群岛（The Friars，41平方公里）、休恩河下游河口（39平方公里）、布尼岛北部廷德博克附近的德恩特卡斯托海峡（D'Entrecasteaux Channel，7平方公里）以及玛丽亚岛（Maria Island，3平方公里，西侧海域）。除德恩特卡斯托海峡与玛丽亚岛外，所有测区的海底视频表征工作均聚焦于基岩礁及其邻近海底区域。
