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 data-set comprises inorganic element data from surface seabed sediments (~0-2 cm) in the Timor Sea.

Lineage

Bottom sediments were collected using a Smith McIntyre grab. The surface sediments (~0-2 cm) within the grab were spooned into falcon vials and the porewaters were removed by centrifugation. The samples were then frozen for transport to the laboratories at Geoscience Australia where they were freeze-dried and ground in a tungsten carbide mill. Major and trace elements were determined by X-ray fluorescence at Geoscience Australia using a Phillips PW204 4kW sequential spectrometer. A fuller suite of trace elements was determined using a AGILENT 7500ce ICP-MS. The attribute accuracies are moderate: <5% for majors and <10% for trace elements. Thanks to the crew of the RV Solander for help with sample aquisition.
