Radiocarbon Sampling in the North Atlantic

9618017 关键 在这个项目中，主要研究员将监督收集大约400个水样，对北大西洋西部的两个赤道断面进行放射性碳（C-14、C-13）分析，作为对世界海洋环流实验的辅助贡献。 作为世界海洋环流实验组织大西洋环流和气候实验（ACCE）的一部分，将在沿着西经52度和西经65度的两个水文剖面上进行取样， 这是自原子弹试验期间无意中将C- 14注入海洋以来的第三次。 先前的取样已经完成 在地球化学海洋剖面期间， 瞬态示踪观测（TTO）计划。 最近的发现提出了更明确的方法来使用这些测量来约束循环模型。

9618017 Key In this project the PI will oversee the collection of about 400 water samples to be analyzed for radiocarbon (C-14, C-13) on two meridional sections in the western North Atlantic as an ancillary contribution to the World Ocean Circulation Experiment (WOCE). Two hydrographic sections, along 52 deg W and 65 deg W, to be conducted as part of the WOCE Atlantic Circulation and Climate Experiment (ACCE), offer an opportunity to sample several stations for the third time since the inadvertent injection of C- 14 into the ocean during A-bomb testing. Previous sampling was done during GEOSECS (GEochemical Ocean SECtionS) and the Transient Tracer Observations (TTO) program. Recent discoveries have suggested more definitive ways to use these measurements to constrain circulation models.
