Abstract

The Petrel Sub-basin Marine Environmental Survey GA-0335, (SOL5463) was undertaken using the RV Solander during May 2012 as part of the Commonwealth Government's National Low Emission Coal Initiative (NLECI). The survey was undertaken as a collaboration between the Australian Institute of Marine Science (AIMS) and GA. The purpose was to acquire geophysical and biophysical data on shallow (less then 100m water depth) seabed environments within two targeted areas in the Petrel Sub-basin to support investigation for CO2 storage potential in these areas. This 10 sample data-set comprises sediment oxygen demand data (expressed as % saturation per gram dry weight) from surface seabed sediments (~0-2 cm) in the Timor Sea.

Lineage

Bottom sediments were collected using a Smith McIntyre 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 Solander for help with sample acquisition.
