Seabed environments and shallow geology of the Vlaming sub-basin, Western Australia: Sediment oxygen demand of seabed sediments.

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 highly suitable for CO2 storage. The principal aim of the Vlaming Sub-basin marine survey (GA survey number GA334) was to look for evidence of any past or current gas or fluid seepage at the seabed, and to determine whether these features are related to structures (e.g. faults) in the Vlaming Sub-basin that may extend up to 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 research addresses key questions on the potential for containment of CO2 in the Early Cretaceous Gage Sandstone (the basin's proposed CO2 storage unit) and the regional integrity of the South Perth Shale (the seal unit that overlies the Gage Sandstone). This dataset comprises sediment oxygen demand measurments from seabed sediments.

Statement

Bottom sediments were collected using a Shipek grab. Bulk sub-samples (6.5 ml) of surface sediment (0-2 cm) were incubated in BOD bottles for ~24 hrs in the dark at sea surface temperatures. Dissolved oxygen concentrations (and saturation values) were measured at the start and finish of each incubation. Results were expressed on a per g dwt basis utilising a separate sample to measure %water. Analyses were corrected for blanks (filtered seawater). The accuracies of the O2 measurements were +/- 1 mg/L. The accuracy of the scale used to measure wet/dry weights was better than 1%.

Thanks to the crew of the RV Southern Supporter for help with sample collection.
