Bathymetry grid of southern part of Jervis Bay survey area (south 4)

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. jb_s4 is an ArcINFO grid of southern part of Jervis Bay survey area (south4 is part of Darling RD grid) produced from the processed EM3002 bathymetry data using the CARIS HIPS and SIPS software. 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海洋调查（项目编号GA303、GA305、GA309、GA312），旨在绘制海床测深图，并通过同步采集表层沉积物（用于纹理分析与生物地球化学分析）与底内生物样本、利用水下拖曳式视频与静态摄影观测底栖生境、测量海洋潮汐与波浪生成流，以表征底栖环境。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“金布拉号”研究船（Research Vessel Kimbla）完成。水深测绘、样本采集及潮汐/波浪测量的作业区域集中于杰维斯湾南部一块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，在达令路网格之外的典型生境类型区域，还开展了沿航线的补充采样、静态摄影及水深测绘工作。jb_s4是基于经处理的EM3002型水深测量数据，使用CARIS HIPS与SIPS软件生成的杰维斯湾南部调查区域的ArcINFO网格（其中south4为达令路网格的组成部分）。本数据集为CERF海洋生物多样性中心（CERF Marine Biodiversity Hub）的共建贡献成果。
