Extractable element 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 81 sample dataset comprises acidextractable concentrations of trace elements (Fe, Mn, Co, Ni, Cu, Zn, Ge, As, Cd and Pb) in surface seabed sediments (~0 to 2 cm) 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年在新南威尔士州杰维斯湾开展了海洋调查（项目编号：GA303、GA305、GA309、GA312），旨在通过以下工作绘制海底水深地形图并表征底栖环境：同步采集表层沉积物（用于纹理与生物地球化学分析）和底内动物样本、采用水下拖曳视频及静态摄影技术观测底栖生境、测量海洋潮汐与波浪生成流。本次调查的数据与样本采集工作依托国防科学技术组织（Defence Science and Technology Organisation, DSTO）的“Kimbla”号研究船完成。海底水深测绘、采样以及潮汐/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（命名为达令路网格，Darling Road Grid, DRG），该区域涵盖海湾入口。此外，研究团队在达令路网格以外的典型生境类型区域沿航线开展了补充采样、静态摄影及海底水深测绘工作。本数据集包含杰维斯湾表层海底沉积物（深度约0至2厘米）中可酸提取态微量元素（Fe、Mn、Co、Ni、Cu、Zn、Ge、As、Cd及Pb）的浓度数据，共计81组样本。本数据集为CERF海洋生物多样性中心（CERF Marine Biodiversity Hub）的贡献数据。
