Vlaming Sub-Basin Marine Environmental Survey (GA-0334/S. Supporter GP1373)(NCIP Program) - High Resolution Bathymetry grids

Geoscience Australia conducted a marine survey to provide seabed environmental information to support the assessment of the CO2 storage potential of the Vlaming Sub-Basin. The survey was undertaken under the Australian Government's National CO2 Infrastructure Plan (NCIP) to help identify sites suitable for the long term storage of CO2. The major aim of this survey was to look for evidence of any gas fluid seepage at the seabed and wether the location had faults that have been identified in a number of seismic lines. The survey also mapped seabed biota in the area of interest to indentify any biota communities that are related with seepage. This research addresses key questions of the regional seal integrity of the Southern Perth Shale and the potential for storing of CO2 in the Early Cretaceous Gage Sandstone. The survey was conducted by Fugro's Southern Supporter in the Vlaming Sub-Basin, North and South of Rotnest Island between the period of the 17th of March to the 20th of April 2012. Shallow seismic sub bottom profiler data were acquired as well as high resolution multibeam bathymetry and backscatter data during the survey.

澳大利亚地球科学局（Geoscience Australia）开展了一项海洋勘测，以获取海底环境信息，支撑弗拉明次盆地（Vlaming Sub-Basin）的二氧化碳（CO2）封存潜力评估工作。本次勘测系依据澳大利亚政府《国家二氧化碳基础设施计划（NCIP）》实施，旨在助力识别适合长期封存二氧化碳的场址。此次勘测的核心目标包括：探寻海底存在气体流体渗漏的证据，以及核查该区域是否存在多条地震测线中已探明的断层。此外，勘测还对目标海域的海底生物群落开展了测绘，以识别与渗漏活动相关的生物群落。本研究旨在解答两项关键科学问题：南珀斯页岩（Southern Perth Shale）的区域盖层完整性，以及早白垩世盖奇砂岩（Early Cretaceous Gage Sandstone）的二氧化碳封存潜力。本次勘测由福格公司（Fugro）的“南方支持者号”（Southern Supporter）于2012年3月17日至4月20日期间，在罗特内斯特岛（Rotnest Island）南北两侧的弗拉明次盆地海域开展。勘测期间同步采集了浅层地震海底剖面仪数据、高分辨率多波束测深与反向散射数据。本数据集不得用于导航用途。
