Bathymetry grid of northern part of Jervis Bay survey area

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_n is an ArcINFO grid of northern part of Jervis Bay survey area 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了编号为GA303、GA305、GA309、GA312的海洋调查工作，旨在绘制海底水深地形图，并通过同步采集表层沉积物（用于纹理与生物地球化学分析）及底内动物、利用水下拖曳视频与静态摄影观测底栖生境，以及测量海洋潮汐与波浪生成海流，来表征底栖环境。本次调查的数据与样本均由国防科学技术组织（Defence Science and Technology Organisation, DSTO）的“Kimbla”号研究船获取。水深测绘、采样及潮汐/波浪测量工作集中于杰维斯湾南部一块3×5公里的调查网格（命名为达令路网格，Darling Road Grid，简称DRG），该区域涵盖海湾入口。此外，研究团队还在达令路网格之外的典型生境区域开展了额外采样、静态摄影以及沿航线的水深测绘。jb_n为利用CARIS HIPS和SIPS软件处理EM3002水深数据后生成的杰维斯湾北部调查区域ArcINFO网格（ArcINFO grid）。本数据集是CERF海洋生物多样性中心（CERF Marine Biodiversity Hub）的贡献成果之一。
