Bathymetry grid of near the beecroft head 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. beecrofthead is an ArcINFO grid near the beecroft head 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年在新南威尔士州杰维斯湾开展了编号为GA303、GA305、GA309、GA312的海洋调查，旨在绘制海底水深地形图，并通过同步配套采集表层沉积物（用于纹理特征与生物地球化学分析）及底内动物样本、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，以表征底栖生境的特征。本次调查的数据与样本采集工作由澳大利亚国防科学与技术组织（Defence Science and Technology Organisation, DSTO）的"Kimbla"号研究船完成。水深测绘、样本采集及潮汐/波浪测量工作主要集中于杰维斯湾南部的3×5公里调查网格（命名为达令路网格，Darling Road Grid, 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的样本采集、静态摄影及沿调查航线的水深测绘。beecrofthead为基于经处理的EM3002多波束水深数据，通过CARIS HIPS与SIPS软件生成的杰维斯湾调查区比克罗夫特岬附近的ArcINFO网格。本数据集是CERF海洋生物多样性中心（CERF Marine Biodiversity Hub）的共建贡献成果。
