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.澳大利亚地球科学局（Geoscience Australia）于2007、2008及2009年在新南威尔士州（NSW）杰维斯湾开展海洋调查（项目编号GA303、GA305、GA309、GA312），旨在绘制海底水深图并表征底栖环境，具体工作包括：同步采集表层沉积物样品（用于纹理分析与生物地球化学研究）及底内生物样品、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诱导流。本次调查的数据与样品采集依托国防科学技术组织（Defence Science and Technology Organisation, DSTO）旗下的“肯布拉号”研究船（Research Vessel Kimbla）完成。水深测绘、样品采集及潮汐/波浪测量工作主要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, DRG），覆盖海湾入口区域。研究团队还在达令路网格外的典型生境类型沿线开展了补充采样、静态摄影及过境航线水深测绘工作。jb_n为依托CARIS HIPS和SIPS软件（CARIS HIPS and SIPS）处理EM3002测深数据（EM3002）后生成的杰维斯湾北部调查区域ArcINFO网格（ArcINFO Grid）数据集。本数据集为英联邦环境研究设施海洋生物多样性枢纽（CERF Marine Biodiversity Hub）的支撑成果。
