Organic and inorganic geochemistry data for plants and algae 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 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 18 sample data set comprises %TOC, %TN, TOC/TN ratios, carbon and nitrogen isotopic ratios and major and trace element concnetrations of plant and algae tissues from Jervis Bay. The red algae likely belong to the genera Gracilaria edulis and Acrosorium venulosum which are abundant in the Bay, and are often observed to washup on the beaches.

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 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, ground in a PSZ mill and split into two fractions. One fraction was then decarbonated. The decarbonated powders were sent to Environmental Isotopes Pty Ltd (Sydney) for isotopic analysis by mass spectrometry. Major and trace elements were determined on the carbonatecontaining fraction by Xray fluorescence at Geoscience Australia using a Phillips PW204 4kW sequential spectrometer. Negative values in the trace element data indicate that the particular element was below the indicated level of analytical detection.
