Abstract
Geoscience Australia undertook a marine survey of the Vlaming Sub-basin in March and April 2012 to provide seabed and shallow geological information to support an assessment of the CO2 storage potential of this sedimentary 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 within reasonable distances of major sources of CO2 emissions. The Vlaming Sub-basin is located offshore from Perth, Western Australia, and was previously identified by the Carbon Storage Taskforce (2009) as potentially suitable for CO2 storage. The principal aim of the Vlaming Sub-basin marine survey (GA survey number GA0334) was to look for evidence of fault reactivation and of any past or current gas or fluid seepage at the seabed. The survey also mapped seabed habitats and biota in the areas of interest to provide information on communities and biophysical features that may be associated with seepage. This data package brings together the following datasets which describe biophysical aspects of seafloor sediments: GEOCAT#74276. Underwater video footage from the Vlaming Sub-basin (GA0334). GEOCAT#76463. GA0334 Vlaming sub-basin Species identification of worms from grab. GEOCAT#78540. Vlaming Sub-Basin Marine Environmental Survey (GA-0334/S.
