Bathymetry grid of the Freycinet 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. freycinet_160 is an ArcINFO grid of the Freycinet 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年至2009年间在塔斯马尼亚州东南部开展了编号为GA0315的海洋调查，旨在通过水下牵引视频（underwater towed video）观测生境，完成海底水深地形（seabed bathymetry）测绘与底栖环境（benthic environments）特征刻画工作。本次调查使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）开展数据采集。

本次水深地形测绘共覆盖7个调查区域，分别为：菲欣纳半岛（Freycinet Peninsula），面积83平方公里，涵盖东海岸及大陆架区域；塔斯曼半岛（Tasman Peninsula），面积117平方公里，涵盖东海岸及大陆架区域；亚瑟港及邻近开放海岸，面积17平方公里；修士群岛（The Friars），面积41平方公里，位于布鲁尼岛以南；休恩河下游河口，面积39平方公里；德恩特卡斯托海峡（D'Entrecasteaux Channel），面积7平方公里，地处布鲁尼岛以北的廷德博克斯（Tinderbox）海域；玛丽亚岛（Maria Island），面积3平方公里，覆盖岛西海岸区域。

除德恩特卡斯托海峡与玛丽亚岛外，所有测绘区域的海底视频特征刻画工作均聚焦于基岩礁及其邻近海底区域。`freycinet_160`为利用CARIS HIPS与SIPS软件处理EM3002水深测量数据后生成的菲欣纳半岛调查区ArcINFO格网数据集（ArcINFO grid）。本数据集为CERF海洋生物多样性枢纽（CERF Marine Biodiversity Hub）的贡献数据。
