Bathymetry of Bremer Marine Park

Australia has established a network of 58 marine parks within Commonwealth waters covering a total of 3.3 million square kilometres, or 40 per cent of our exclusive economic zone (excluding Australian Antarctic Territory). These parks span a range of settings, from near coastal and shelf habitats to abyssal plains. Parks Australia manages the park network through management plans that came into effect for all parks on 1 July 2018. Geoscience Australia is contributing to their management by collating and interpreting existing environmental data, and through the collection of new data. This includes compiling existing bathymetry datasets for select marine parks. This dataset includes a compilation of multibeam sonar bathymetry (gridded to 100 m spatial resolution) for Bremer Marine Park, in the South-west Marine Park Network. The park incorporates Bremer Canyon and adjacent smaller canyons that incise the continental slope and outer shelf. This research is supported by the National Environmental Science Program (NESP) Marine Biodiversity Hub through Project D1.

澳大利亚在联邦水域内建立了由58个海洋保护区组成的网络，总面积达330万平方公里，占本国专属经济区的40%（不包括澳大利亚南极领地）。该保护区网络覆盖从近岸与陆架栖息地到深海平原的各类生境。澳大利亚海洋公园管理局（Parks Australia）通过2018年7月1日起对所有保护区全面生效的管理计划，对该网络实施管理。澳大利亚地球科学局（Geoscience Australia）正通过整理与解读现有环境数据、采集新数据的方式为保护区管理提供支持，其中包括为选定的海洋保护区汇编现有水深地形数据集。本数据集包含西南海洋保护区网络（South-west Marine Park Network）中布雷默海洋保护区（Bremer Marine Park）的多波束声呐水深地形数据，该数据已网格化至100米空间分辨率。该保护区涵盖布雷默峡谷及切入大陆坡与外陆架的相邻小型峡谷。本研究由国家环境科学计划（National Environmental Science Program, NESP）海洋生物多样性中心通过D1项目资助。
