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.澳大利亚地质调查局（Geoscience Australia）于2007年、2008年及2009年在新南威尔士州杰维斯湾（Jervis Bay）开展了编号为GA303、GA305、GA309、GA312的海洋勘测工作，旨在绘制海底水深图并表征底栖环境，具体手段包括：同位采集表层沉积物用于结构与生物地球化学分析、采集底内动物，利用水下拖曳视频与静态摄影观测底栖生境，以及测量海洋潮汐与海浪生成海流。本次勘测的数据与样品采集依托国防科学技术组织（Defence Science and Technology Organisation, DSTO）的“Kimbla”号研究船完成。水深测绘、采样及潮汐/海浪测量工作集中于杰维斯湾南部一片面积为3×5千米的勘测网格——达令路网格（Darling Road Grid, DRG），该区域涵盖海湾湾口。此外，针对达令路网格外的典型底栖生境类型，沿航线额外开展了采样、静态摄影及水深测绘工作。本数据集共包含81份样品数据，涵盖杰维斯湾表层海底沉积物（约0至2厘米深度）中多种酸可提取态微量元素的浓度，具体包括铁（Fe）、锰（Mn）、钴（Co）、镍（Ni）、铜（Cu）、锌（Zn）、锗（Ge）、砷（As）、镉（Cd）与铅（Pb）。
