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、2008及2009年在杰维斯湾（新南威尔士州，NSW）开展海洋调查（项目编号：GA303、GA305、GA309、GA312），旨在通过同位采样表层沉积物（用于纹理与生物地球化学分析）及底内动物、利用水下拖曳式视频与静态摄影观测底栖生境，辅以海洋潮汐与波浪生成流测量，完成海底水深测绘并表征底栖环境。本次调查的数据与样品均由国防科学技术组织（Defence Science and Technology Organisation, DSTO）的“Kimbla”号研究船采集获取。水深测绘、采样及潮汐/波浪测量工作主要集中于杰维斯湾南部一块名为“达令路网格（Darling Road Grid, DRG）”的3×5 km调查网格区内，该区域涵盖海湾入口。研究团队还在达令路网格之外的典型生境类型区域，沿航线开展了补充采样、静态摄影以及水深测绘工作。jb_s4为杰维斯湾南部调查区域的ArcINFO网格（其中south4为达令路网格的一部分），该数据集由经处理的EM3002测深数据通过CARIS HIPS与SIPS软件生成。本数据集为CERF海洋生物多样性中心（CERF Marine Biodiversity Hub）的贡献成果。
