Jervis Bay Infauna biodiversity data

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 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. Sample diversity indices calculated in PRIMER (version 6) using the species level data from JBinfauna_species (25Oct10).xls. This dataset is a contribution to the CERF Marine Biodiversity Hub.

澳大利亚地球科学局（Geoscience Australia）于2007年、2008年及2009年在新南威尔士州杰维斯湾开展了海洋勘测（航次编号为GA303、GA305、GA309、GA312），旨在开展海床水深测绘（seabed bathymetry）并表征底栖环境（benthic environments），具体工作包括：同步采集表层沉积物（surface sediments）以进行纹理与生物地球化学分析、采集底内生物（infauna）、利用水下拖曳视频与静态摄影观测底栖生境，以及测量海洋潮汐与波浪生成流。本次勘测的数据与样本均由澳大利亚国防科学技术组织（Defence Science and Technology Organisation, DSTO）的“Kimbla”号研究船采集。水深测绘、采样及潮汐/波浪测量工作集中于杰维斯湾南部一块3×5 km的勘测网格——达令路网格（Darling Road Grid, DRG），该网格覆盖海湾入口区域。此外，项目组还在达令路网格之外的典型生境类型沿线开展了附加采样、静态摄影及航道水深测绘工作。研究人员基于JBinfauna_species (25Oct10).xls文件中的物种级数据，使用PRIMER（第6版）计算了样本多样性指数。本数据集为CERF海洋生物多样性中心（CERF Marine Biodiversity Hub）的相关研究提供支撑。
