Organic geochemistry 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 50 sample data set comprises %TOC, %TN, TOC/TN ratios, and carbon and nitrogen isotopic ratios for surface (0.0 to 2.0 cm) sediments from Jervis Bay. This dataset is a contribution to the CERF Marine Biodiversity Hub.

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（New South Wales, NSW）杰维斯湾（Jervis Bay）开展了编号为GA303、GA305、GA309、GA312的海洋勘测工作，旨在绘制海底水深地形图并表征底栖环境，具体手段包括同步采集表层沉积物样品以开展纹理与生物地球化学分析、采集底内生物，利用水下拖曳式摄像与静态摄影观测底栖生境，以及测量海洋潮汐与波浪生成流。数据与样品的采集依托国防科学技术组织（Defence Science and Technology Organisation, DSTO）的“金布拉”号研究船（Research Vessel Kimbla）完成。水深测绘、样品采集及潮汐/波浪测量工作集中于杰维斯湾南部一块3×5千米的勘测网格——达令路网格（Darling Road Grid, DRG），该区域涵盖海湾入口。此外，项目团队还在达令路网格外的典型生境类型区域开展了额外的样品采集、静态摄影以及沿勘测航线的水深测绘工作。本数据集包含采自杰维斯湾的50份0.0至2.0厘米深度表层沉积物的分析数据，具体包括总有机碳百分含量（%TOC）、总氮百分含量（%TN）、碳氮比（TOC/TN）以及碳、氮同位素比值。本数据集为海洋生物多样性中心（CERF Marine Biodiversity Hub）的贡献成果。
