Radiocarbon Sampling in the North Atlantic

9618017这一项目的关键是，作为对世界海洋环流实验的辅助贡献，国际海洋研究所将监督对北大西洋西部两个子午线断面上的约400个水样进行放射性碳(C-14、C-13)分析。作为WOCE大西洋环流和气候实验(ACCE)的一部分，将沿着52°W和65°W进行两个水文断面，这是自在原子弹试验期间无意中将C-14注入海洋以来，第三次对几个站进行采样的机会。以前的采样是在GEOSECS(海洋地球化学切片)和瞬变示踪观测(TTO)计划期间进行的。最近的发现已经提出了更明确的方法来使用这些测量来限制环流模型。

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.
