Bathymetry grid of southern part of Jervis Bay survey area (south 2)

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_s2 is an ArcINFO grid of southern part of Jervis Bay survey area (south2 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.

澳大利亚地质调查局（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的海洋勘测工作，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）及底内生物样本、借助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，完成海底水深制图并表征底栖环境特征。
数据及样本采集作业依托国防科学技术组织（Defence Science and Technology Organisation, DSTO）的"金布拉"号（Kimbla）科研考察船开展。
水深制图、样本采集以及潮汐/波浪测量的作业范围集中于杰维斯湾南部一块3×5千米的勘测网格——该网格被命名为"达令路网格"（Darling Road Grid, DRG），区域涵盖海湾入口。
此外，项目还在达令路网格外的典型生境类型沿线开展了额外采样、静态摄影以及过境航线水深制图工作。
jb_s2为基于处理后的EM3002水深数据，通过CARIS HIPS和SIPS软件生成的杰维斯湾南部勘测区域ArcINFO网格（其中south2为达令路网格的组成部分）。
本数据集为CERF海洋生物多样性枢纽（CERF Marine Biodiversity Hub）的贡献成果。
