TCO2 fluxes and pools for 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 data set comprises TCO2 flux and pool data for surface seabed sediments (~0 to 2 cm). This dataset is a contribution to the CERF Marine Biodiversity Hub.

澳大利亚地质科学局（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），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、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生成流，完成海底水深测绘并表征底栖环境特征。本次调查使用国防科学技术组织（Defence Science and Technology Organisation, DSTO）的“金布拉号”研究船（Research Vessel Kimbla）执行数据与样本采集工作。水深测绘、样本采集及潮汐/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，该网格被命名为“达令路网格（Darling Road Grid, DRG）”，覆盖海湾入口区域。此外，项目还在达令路网格之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。本数据集包含126份样本数据，内容为深度约0至2厘米的表层海底沉积物的总二氧化碳（TCO2）通量与储库数据。本数据集是CERF海洋生物多样性中心（CERF Marine Biodiversity Hub）的贡献成果之一。
