Bathymetry grid of the Tinderbox survey area

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. tindexbox_1m is an ArcINFO grid of the Tinderbox survey area produced from the processed EM3002 bathymetry data using the CARIS HIPS and SIPS software. This dataset is a contribution to the CERF Marine Biodiversity Hub.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实施了编号为GA0315的海洋调查，旨在通过水下拖曳视频观测生境，开展海底水深测绘并表征底栖环境。本次调查的数据采集工作依托塔斯马尼亚水产与渔业研究所（TAFI）的“挑战者号”研究船完成。本次调查共覆盖7个勘测区域，分别为：菲欣纳半岛（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）、亚瑟港及邻近开放海岸（17平方公里）、修士群岛（The Friars，41平方公里，布鲁尼岛以南）、休恩河下游河口（39平方公里）、德恩特卡斯托海峡（D'Entrecasteaux Channel，7平方公里，布鲁尼岛以北廷德博克区域）以及玛丽亚岛（Maria Island，3平方公里，西侧区域）。海底生境的视频表征工作覆盖所有已测绘区域的岩礁底质及相邻海底区域，但德恩特卡斯托海峡与玛丽亚岛区域除外。`tindexbox_1m`为基于经处理的EM3002型测深数据，通过CARIS HIPS与SIPS软件生成的廷德博克调查区ArcINFO网格（ArcINFO grid）数据集。本数据集是CERF海洋生物多样性中心（Marine Biodiversity Hub）的贡献成果之一。
