Reactive Radionuclides in the Eastern North Atlantic, Joint Global Ocean Flux Study

这是作为联合全球海洋通量研究(JGOFS)北大西洋水华实验的一部分进行的一项关于自然和人造放射性核素的分布和颗粒通量的时空变化的研究。要测量的放射性核素充当海洋示踪剂，提供有关生物地球化学过程的速率的基本信息，这些过程支配着海洋水柱中生物起源粒子的命运。这项研究旨在验证这样一种假设，即颗粒物对可溶化学物种的吸收和释放以及海洋水柱中颗粒聚集体的形成和破坏的速度在空间和时间上都会随着海面浮游生物产生率和有机物通量的变化而变化。离开表层。这些数据将在生物速率测量和JGOFS内收集的其他数据的背景下进行解释，并将用于测试生物地球化学模型。

This is a study of spatial and temporal variations in the distributions and particulate fluxes of suite of naturally occurring and man-made radioactive nuclides conducted as part of the Joint Global Ocean Flux Study (JGOFS) North Atlantic Bloom Experiment. The radionuclides to be measured serve as ocean tracers that yield fundamental information about the rates of biogeochemical processes that govern the fate of biogenic particles in the oceanic water column. The study is designed to test the hypothesis that the uptake and release of soluble chemical species by particulate matter and the formation and destruction of particle aggregates in the oceanic water column occur at rates that vary both spatially and temporally in response to variations in the rate of plankton production at the sea surface and the flux of organic matter leaving the surface layer. The data will be interpreted within the context of biological rate measurements and other data to be collected within JGOFS and will be used to test biogeochemical models.
