Backscatter grid of the northern side of the Darling Road survey area of Jervis Bay

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. north1_1m is an ArcGIS layer of the backscatter grid of the northern side of the Darling Road survey area produced from the processed EM3002 and EM3002D backscatter data of the survey area using the CMST-GA MB Process 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和2009年在新南威尔士州（NSW）杰维斯湾开展了编号为GA303、GA305、GA309、GA312的海洋调查，旨在通过同步采集表层沉积物（用于纹理与生物地球化学分析）及底内生物（infauna）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生成流，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、样品采集及潮汐/波浪测量工作主要集中在杰维斯湾南部一块3×5 km的调查网格，该网格被命名为“达令路网格（Darling Road Grid, DRG）”，覆盖海湾入口区域。此外，研究团队还在达令路网格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工作。north1_1m为达令路调查区域北侧的反向散射网格ArcGIS图层（ArcGIS layer），系通过处理调查区域的EM3002与EM3002D反向散射数据，并借助CMST-GA MB Process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。
