X-ray diffraction data for surface seabed sediments in Jervis Bay, NSW (June 2008)

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 42 sample data set comprises the mineraology of surface seabed sediment (~0-2 cm) in Jervis Bay.

澳大利亚地球科学局（Geoscience Australia）于2007、2008及2009年在新南威尔士州杰维斯湾开展海洋调查（项目编号GA303、GA305、GA309、GA312），旨在通过协同采集表层沉积物（surface sediments，用于粒度纹理与生物地球化学分析）及底内动物（infauna）、利用水下拖曳式视频与静态摄影（underwater towed video and stills photography）观测底栖生境（benthic habitats）、测量海洋潮汐与波浪生成流（ocean tides and wave-generated currents），完成海底水深测绘（seabed bathymetry）并表征底栖环境（benthic environments）。
本次调查的数据与样品采集依托国防科学与技术组织（Defence Science & Technology Organisation, DSTO）的“Kimbla”号研究船完成。
海底水深测绘、采样及潮汐/波浪测量工作集中于杰维斯湾南部的3×5 km调查网格——达令路网格（Darling Road Grid, DRG），覆盖海湾入口区域。
在达令路网格外的典型生境类型沿线，还开展了额外采样、静态摄影及过境水深测绘。
本数据集包含42份样品，涵盖杰维斯湾表层海底沉积物（约0~2 cm深度）的矿物学特征。
