X-ray diffraction data for surface seabed sediments in Jervis Bay, NSW (June 2008)
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 & 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 42 sample data set comprises the mineraology of surface seabed sediment (~0-2 cm) in Jervis Bay.

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 laboratory at Geoscience Australia where they were freeze-dried and ground. Mineralogy was was determined on the powders using a a Siemems D500/D501 series X-ray diffractometer. Mineral identification software was used to identify the d-spacing of the peaks, and Siroquant was used to derive a semi-quantitative estimate of mineral abundance. Attribute accuracy is considered moderate (+/- 10%).
Avknowledgements:
Geoscience Australia undertook a series of field campaigns in Jervis Bay (Dec 2007 to present) as part of the Surrogates Program in the Commonwealth (Australia) Environmental Research Facilities (CERF) Marine Biodiversity Hub. Thanks are owning to a range of people for there generous contributions to this study. Scott Corson (the master of the M.V. Kimbla), Matthew Carey, Peter Harris, Mike Hughes, Jodie Smith and Anna Potter provided field support. Billie Poignand and Kylia Wall dried and ground these samples, and Liz Webber undertook the XRD analysis. This dataset is also available online via the OzCoasts (www.ozcoasts.org.au) and MARS ( http://www.ga.gov.au/oracle/mars/) databases.
