Chlorophyll a and Phaeophytin a data for surface seabed sediments in Jervis Bay, NSW (June and August 2008 and February 2009)

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. This 126 sample dataset comprises chlorophyll a and pheophytin a measurements on surface seabed sediments (~0 to 2 cm) from Jervis Bay. 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/波浪测量工作集中于杰维斯湾南部一块3×5千米的调查网格（命名为达令路网格，Darling Road Grid, DRG），覆盖湾口区域。针对达令路网格外的典型生境类型，本次调查还开展了额外的样品采集、静态摄影以及沿航线的水深测绘工作。本126件样品数据集涵盖了杰维斯湾表层海底沉积物（深度约0~2厘米）中的叶绿素a（chlorophyll a）与脱镁叶绿素a（pheophytin a）测量数据。本数据集系向CERF海洋生物多样性中心（CERF Marine Biodiversity Hub）提交的贡献数据。
