Sediment Data for 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 co-located 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 wave-generated 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. Seabed sediment samples were collected by a Shipek grab at a total of 126 locations. (see Anderson et al. 2009). Sediment grabs typically recovered a sample up to 5 cm by 12 cm in area and 5 cm thick, from which a 50 - 100 g sub-sample was taken to a depth of ~2 cm. Sub-samples were stored in plastic bags and refrigerated. 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海洋调查（项目编号GA303、GA305、GA309、GA312），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）与底内生物样品、采用水下拖曳式视频及静态摄影技术观测底栖生境、测量海洋潮汐与波浪驱动流，完成海床水深测绘与底栖环境表征工作。本次调查的数据与样品采集工作由国防科学技术组织（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/波浪测量主要集中在杰维斯湾南部一片名为达令路网格（Darling Road Grid, DRG）的3×5公里调查网格范围内，该区域涵盖海湾入口。此外，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、静态摄影及过境水深测绘工作。研究团队共计在126个站位使用希佩克采泥器（Shipek grab）采集海床沉积物样品（详见Anderson等人2009年的研究成果）。单次采泥通常可获取面积为5厘米×12厘米、厚度5厘米的沉积物样品，随后从中截取深度约2厘米的50至100克子样品。子样品被封装于塑料袋中并冷藏保存。本数据集为CERF海洋生物多样性中心（CERF Marine Biodiversity Hub）的贡献数据集。
