14 C弹作为海洋表层水中CO2的示踪剂，用于研究大气与海洋之间的CO2交换。使用普通货船进行采样，我们已经能够在一定时期内覆盖大西洋、太平洋和印度洋的一些地区。在过去15年中，共测量了89个地点的520个样本。数据以表格和图表的形式呈现。在温带北方纬度观测到的最大14 C浓度（Δ 14 C）约为20%，在南半球纬度则低几个百分点。在上升流区和下降流区，14 C的变化都有夏季最大、冬季最小的季节变化趋势。
Bomb 14C has been used as a tracer for CO2 in ocean surface water to study CO2 exchange between atmosphere and ocean. Using ordinary cargo ships for sampling, we have been able to cover some parts of the Atlantic, Pacific, and Indian Oceans for certain periods. A total number of 520 samples from 89 locations were measured during the last 15 years. The data are presented both in tables and graphs. A maximum 14C concentration (Δ14C) of ca 20% was observed in temperate northern latitudes, and a few per cent lower at southern latitudes. A seasonal trend in the 14C variation, with summer maximum and winter minimum, was observed both in downwelling and upwelling areas.
