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 & 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.More Information:Radke, L.C., Huang, Z., Przeslawski, R., Webster, I.T., McArthur, M.A., Anderson, T.J., P.J. Siwabessy, Brooke, B. 2011.

澳大利亚地质科学局（Geoscience Australia）于2007年、2008年及2009年在新南威尔士州（NSW）杰维斯湾（Jervis Bay）开展了编号为GA303、GA305、GA309、GA312的海洋调查，旨在通过同步采集表层沉积物（用于纹理与生物地球化学分析）及底内动物（infauna）样本、采用水下拖曳式视频与静态摄影技术观测底栖生境（benthic habitats）、测量海洋潮汐与波浪生成流，绘制海底水深地形图并刻画底栖环境特征。
本次调查使用国防科学与技术组织（Defence Science & Technology Organisation, DSTO）的“金布拉号”研究船（Research Vessel Kimbla）采集数据与样本。水深测绘、样本采集及潮汐/波浪测量工作主要集中在杰维斯湾南部一块3×5千米的调查网格内，该网格被命名为达令路网格（Darling Road Grid, DRG），涵盖海湾入口区域。
此外，研究团队还在达令路网格外的典型生境类型沿线开展了额外采样、静态摄影及航道水深测绘工作。本数据集包含128份样本数据，均来自表层海底沉积物（约0~2厘米深度）的X射线荧光分析（X-ray fluorescence analysis）结果，涵盖常量元素、微量元素与痕量元素，同时附带沉积物表面积相关数据。
