Extractable element data for surface seabed sediments in Jervis Bay, NSW (August 2008 and February 2009)

Geoscience Australia carried out marine surveys in Jervis Bay (NSW) in 2007, 2008 and 2009 (GA303, GA305, GA309, GA312) to map seabed bathymetry and characterise benthic environments through colocated sampling of surface sediments (for textural and biogeochemical analysis) and infauna, observation of benthic habitats using underwater towed video and stills photography, and measurement of ocean tides and wavegenerated currents. Data and samples were acquired using the Defence Science and Technology Organisation (DSTO) Research Vessel Kimbla. Bathymetric mapping, sampling and tide/wave measurement were concentrated in a 3x5 km survey grid (named Darling Road Grid, DRG) within the southern part of the Jervis Bay, incorporating the bay entrance. Additional sampling and stills photography plus bathymetric mapping along transits was undertaken at representative habitat types outside the DRG.


This 81 sample dataset comprises acidextractable concentrations of trace elements (Fe, Mn, Co, Ni, Cu, Zn, Ge, As, Cd and Pb) in surface seabed sediments (~0 to 2 cm) from Jervis Bay.

Statement

Bottom sediments were collected using a small Shipek type grab sampler.This device can collect an intact sample of sediment up to 5 cm by 12 cm in area and 5 cm thick. Upon triggering, the grab immediately covers the sample, which prevents washout of fine sediment during retrieval to the surface. The surface sediments (~0 to 2 cm) within the grab were spooned into acidwashed falcon vials and the porewaters were removed by centrifugation (9000 rpm; 5 minutes). The samples were then frozen for transport to the laboratories at Geoscience Australia where they were freezedried and ground in a PSZ mill. Hydrochloric acid (HCl) metal digests of sediments were also undertaken following the protocol of Snape et al. (2004). Briefly, 20 ml of a 1M HCl solution and 1 g freezedried sediment were mixed for 4 hours at room temperature, prior to centrifugation and then filtration into acidcleaned containers. 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 checked and corrected for. The analyses are provided as mg/kg dry weight.
