Bathymetry grid of the sisters, north of Tasman Peninsula 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. sisters_160 is an ArcINFO grid of the sisters, north of Tasman Peninsula 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年与2009年在塔斯马尼亚东南部开展了编号为GA0315的海洋科考作业，旨在通过水下牵引式视频观测生境，绘制海底水深地形（seabed bathymetry）图并表征底栖环境（benthic environment）。本次科考采用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（Research Vessel Challenger）采集数据。

本次作业共覆盖7个测绘区域，具体包括：菲欣纳半岛（Freycinet Peninsula，东海岸及陆架，面积83平方千米）、塔斯曼半岛（Tasman Peninsula，东海岸及陆架，面积117平方千米）、阿瑟港及邻近开放海岸（面积17平方千米）、"修士群岛"（The Friars，布鲁尼岛以南，面积41平方千米）、休恩河下游河口（面积39平方千米）、德恩特雷卡斯托海峡（D'Entrecasteaux Channel，位于布鲁尼岛以北廷德博基附近，面积7平方千米）以及玛丽亚岛（Maria Island，西侧区域，面积3平方千米）。

海底的视频底栖环境表征工作聚焦所有测绘区域内的岩礁海底及毗邻海底，但德恩特雷卡斯托海峡与玛丽亚岛区域除外。

sisters_160为基于经处理的EM3002水深测绘数据，通过CARIS HIPS与SIPS软件生成的、位于塔斯曼半岛测绘区以北的"修士群岛"（Sisters）的ArcINFO网格数据集。

本数据集为CERF海洋生物多样性枢纽（CERF Marine Biodiversity Hub）的贡献数据集。
