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).

澳大利亚地质调查局（Geoscience Australia）于2007、2008及2009年在杰维斯湾（新南威尔士州，New South Wales, NSW）开展海洋调查（项目编号GA303、GA305、GA309、GA312），旨在通过协同采集表层沉积物（用于纹理与生物地球化学分析）与底内生物、利用水下拖曳式视频及静态摄影观测底栖生境、测量海洋潮汐与波浪驱动流，完成海底水深地形测绘并表征底栖环境。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”研究船采集数据与样品。水深地形测绘、采样及潮汐/波浪测量工作集中于杰维斯湾南部的3×5千米调查网格（命名为达令路网格，Darling Road Grid, DRG），覆盖海湾入口区域。此外，针对达令路网格外的典型生境类型，沿过境航线开展了附加采样、静态摄影及水深地形测绘工作。
本数据集包含126份样品数据，涵盖表层海底沉积物（深度约0至2厘米）的总二氧化碳（TCO2）通量与储库数据。
