资源简介:
Geoscience Australia carried out marine surveys in south-east 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 GA0315_SETasi folder contains video footage; the excel file is the video characterisation data. Underwater video footage represents raw data. Video characterisation dataset include percent cover of substate.

澳大利亚地球科学局(Geoscience Australia)于2008年及2009年在塔斯马尼亚东南部实施了海洋调查(项目编号GA0315),旨在测绘海底水深地形,并通过水下拖曳视频观测栖息地来表征底栖环境。本次调查搭载塔斯马尼亚水产与渔业研究所(TAFI)的“挑战者号”研究船开展作业。 本次水深测绘共覆盖7个调查区域,具体如下:菲辛那半岛(Freycinet Peninsula,原文笔误为Pensinula),面积83平方千米,位于东海岸及陆架区域;塔斯曼半岛(Tasman Peninsula),面积117平方千米,位于东海岸及陆架区域;亚瑟港及邻近开放海岸(Port Arthur and adjacent open coast),面积17平方千米;修士群岛(The Friars),面积41平方千米,地处布尼岛以南;休恩河下游河口(lower Huon River estuary),面积39平方千米;德恩特卡斯托海峡(D Entrecastreaux,正确拼写应为D'Entrecasteaux Channel),面积7平方千米,位于布尼岛以北的廷德博克斯(Tinderbox)区域;以及玛丽亚岛(Maria Island),面积3平方千米,覆盖其西海岸区域。 水下视频的底栖环境表征工作针对所有已测绘区域内的基岩礁及邻近海底区域开展,但德恩特卡斯托海峡与玛丽亚岛除外。 GA0315_SETasi文件夹存储有原始视频影像数据,配套的Excel文件则为视频表征数据集。该数据集包含底质覆盖百分比相关信息。
