X-ray fluorescence and particle surface area data for surface seabed sediments in Jervis Bay, NSW (June and 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 co-located 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 wave-generated 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 128 sample data set comprises major, minor and trace elements derived from x-ray fluorescence analysis of surface seabed sediments (~0-2 cm). Sediment surface area data are also presented.

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 wash-out of fine sediment during retrieval to the surface. The surface sediments (~0-2 cm) within the grab were spooned into 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 freeze-dried and ground in a PSZ mill, after first removing a sub-sample (unground) for surface area analysis. Major and trace elements were determined by X-ray fluorescence at Geoscience Australia using a Phillips PW204 4kW sequential spectrometer. Surface areas were determined using a 5-point Brunauer-Emmett-Teller (BET) adsorption isotherm on a Quantachrome NOVA 2200e analyser, with nitrogen used as the adsorbate. The samples were first cleaned of organic matter by slow heating for 12 hours to 350oC. Negative values in the trace element data indicate that the element was below the indicated level of analytical detection. The data are provided in weight % and ppm.
