2019 Hydrographic surveys of Freycinet, Huon and Tasman Fracture Marine Parks for Parks Australia

IMAS/CSIRO undertook a multibeam mapping campaign in eastern and Southern Tasmania to map shelf waters of the Freycinet, Huon and Tasman Fracture Marine Parks and several reference areas for the Tasman Fracture Park, including waters around Pedra Brancha and South-west Cape. The dataset includes a post-processed transit along the mid-shelf i=of Western Tasmania. The dataset includes raw mutibeam outputs and post-processed data, including Caris Files, xyz data and geotiffs. A data report for this has been produced by CSIRO. The study was intended to increase knowledge of the distribution of habitats within the SE Australian Australian Marine Park network, and at nearby reference areas with similar habitat. This information is required to underpin subsequent biological monitoring of key habitats within the AMP network, and to contrast the observations within parks with nearby fished locations to determine the extent that changes in biological communities are driven by natural vs anthropogenic pressures.

IMAS/CSIRO在塔斯马尼亚州东部及南部海域开展多波束测深航次作业，对弗雷西内、胡恩与塔斯曼断裂带海洋公园的陆架水域，以及塔斯曼断裂带海洋公园的多处参考区域（含佩德拉布兰查周边海域与西南角海域）进行测绘。本数据集包含西塔斯马尼亚州中陆架海域的后处理航行测深数据，同时涵盖原始多波束输出数据与各类后处理成果，具体包括Caris文件、XYZ格式数据及GeoTIFF格式文件。CSIRO已针对本数据集编制专项数据报告。本研究旨在加深对澳大利亚东南部海洋公园网络及邻近相似生境参考区域内生境分布的认知，相关信息可为澳大利亚海洋公园（AMP）网络内关键生境的后续生物监测提供基础支撑，并通过对比海洋公园内部与邻近捕捞区域的观测结果，明确生物群落变化受自然压力与人为压力驱动的相对程度。
