Barium Geochemistry in the South Atlantic: SAVE

海洋钡的分布将通过绘制南大西洋钡的三维分布来确定。在南大西洋环流边界和内部的过程将在涉及生物产生的颗粒的独特摄取和释放途径的背景下进行研究。正在研究的科学假设是，在有机物衰变的微环境中，钡是无机沉淀的。大约1300个样本已经在SAVE第1-5次测试期间收集，另外400个样本将在1990年早期流星巡航11期间获得。建立了一种快速精确测定海水中钡的方法，并将用于这些样品的分析。

Oceanic barium distributions will be defined by mapping the 3- dimensional distributions of Ba in the South Atlantic. Processes at the boundaries and in the interior of the south Atlantic gyre will be studied in the context of the unique uptake and release pathway involving biologically produced particles. The scientific hypothesis under investigation is that barium is inorganically precipitated in microenvironments during the decay of organic matter. %%% Approximately 1300 samples have been collected during SAVE legs 1-5, and another 400 samples will be obtained during Meteor cruise 11 in early 1990. A rapid and precise method for determination of Ba in seawater has been developed and will be used for the analysis of these samples.
