Petrel Sub-basin Marine Survey (GA-0335 / SOL5463) (NLECI Program) - Seabed Geochemistry / Porewater TCO2 and TCO2 flux
The Petrel Sub-basin Marine Environmental Survey GA-0335, (SOL5463) was undertaken by 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 dataset comprises TCO2 pools (0-2cm) and fluxes calculated from bottle incubation experiments (24 hours).

Bottom sediments were collected using a Smith McIntyre grab. Immediately after the grab was back aboard, the surface sediments were spooned into two 58 ml falcon vials for the vial incubation experiments. No later than 30 minutes after collection, the porewaters from one of the two falcon vials (time = zero (t0)) were extracted by centrifugation (8890 rpm; 5 minutes) and syringe-filtered (0.45 ?m) into 3 ml containers that had been pre-charged with 0.025 ml of mercuric chloride. Approximately 24 hours later, the second of the two falcon vials from each site (time = one (t1)) were sampled by the same method. The porewater extracts were stored in the refrigerator prior to analysis for TCO2 concentrations.These concentrations were measured at Geoscience Australia using an AS-C3 DIC analyser (Apollo SciTech), with a certified reference material as a standard.The TCO2 flux measurements represent the amount of CO2 produced by incubating sediment over a ~24 hour period, normalised to the volume of sediment used in the incubation. The TCO2 pool measurements constitute the TCO2 concentrations of the t=0 sample. The average %RSD of the precisions and accuracies of the dissolved inorganic carbon measurements were 0.49 and 100% respectively. The accuracy of the wet/dry weight used in the calculations were better than 1%.
Thanks to the crew of the RV Solander for help with sample acquisition.
