Bathymetry grid of the western side of Maria island 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. maria_1 is an ArcINFO grid of the western side of Maria Island 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的海洋勘测项目，旨在绘制海底水深地形图，并通过水下拖曳视频观测生境以表征底栖环境特征。本次数据采集依托塔斯马尼亚水产与渔业研究所（TAFI）的“挑战者号”研究科考船完成。本次水深测绘覆盖7个勘测区域，分别为：菲欣纳半岛（Freycinet Peninsula，原文拼写笔误为Pensinula，面积83平方千米，涵盖东海岸及陆架区域）、塔斯曼半岛（Tasman Peninsula，面积117平方千米，涵盖东海岸及陆架区域）、亚瑟港及邻近开放海岸（面积17平方千米）、修士群岛（The Friars，面积41平方千米，位于布鲁尼岛以南）、休恩河下游河口（面积39平方千米）、德恩特卡斯托海峡（D'Entrecasteaux Channel，原文拼写笔误为D Entrecastreaux，面积7平方千米，地处布鲁尼岛以北的廷德博克区域），以及玛丽亚岛（Maria Island，面积3平方千米，涵盖西侧区域）。海底底栖生境的视频表征工作覆盖所有测绘区域内的岩礁及邻近海底区域，但德恩特卡斯托海峡与玛丽亚岛区域除外。maria_1为采用CARIS HIPS与SIPS软件处理EM3002测深数据后生成的玛丽亚岛勘测区域西侧的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）的贡献项目成果。
