Seafloor environments of the northern Lord Howe Rise, Eastern Australia: Extractable metal concentrations in seabed sediments.
Geoscience Australia marine reconnaissance survey TAN0713 to the Lord Howe Rise offshore eastern Australia was completed as part of the Federal Government's Offshore Energy Security Program between 7 October and 22 November 2007 using the New Zealand Government's research vessel Tangaroa. The survey was designed to sample key, deep-sea environments on the east Australian margin (a relatively poorly-studied shelf region in terms of sedimentology and benthic habitats) to better define the Capel and Faust basins, which are two major sedimentary basins beneath the Lord Howe Rise. Samples recovered on the survey contribute to a better understanding of the geology of the basins and assist with an appraisal of their petroleum potential. They also add to the inventory of baseline data on deep-sea sediments in Australia. The principal scientific objectives of the survey were to: (1) characterise the physical properties of the seabed associated with the Capel and Faust basins and Gifford Guyot; (2) investigate the geological history of the Capel and Faust basins from a geophysical and geological perspective; and (3) characterise the abiotic and biotic relationships on an offshore submerged plateau, a seamount, and locations where fluid escape features were evident. This dataset comprises Fe, Co, Cd, Cu, Zn, Ni and Mn concentrations after extraction of seabed sediments in cold, dilute HCl.

Bottom sediments were collected using either a box core, benthic sled or Van Veen Grab. Cold dilute hydrochloric acid (1M) metal digests of freeze dried sediments were undertaken following the protocol of Snape et al. (2004). The HCl extracts were analysed by quadrupole ICP-MS at the University of Canberra. All major interfering elements/compounds (i.e., Cl on V, Cr, As and Se) were corrected for. Average %RSD for two stations run in duplicate were 44.1% (Fe), 6.4% (Co), 8.2% (Cd), 1.6% (Cu), 6% (Zn), 12.9% (Ni) and 15.1% (Mn).

Thanks to the crew of the RV Solander for help with sample collection, and Frank Krykowa (University of Canberra) for elemental analysis.
