Time series data for the major compounds in the cycle of dime thylsulfide in open ocean water will be integrated with experimental studies to address controlling processes. DMS, DMSP, and DMSO will be measured in Bermuda waters in conjunction with the time-series studies at the Bermuda Atlantic Time-Series program. Complementary chemical and biological data collected as part of the JGOFS program will provide insights into the importance of blooms and phytoplankton speciation to the DMS cycle. Specific processes involved in the cycling of DMS, its precursors an its products, will be investigated in coordinated laboratory experiments. Time-series measurements and laboratory experiments will be linked by a series of short but intensive process-oriented field studies at the Bermuda site to test hypotheses derived from time-series and laboratory work. The major goal of the project is to identify and quantify the key controlling processes throughout the annual cycle.

开放海水中甲基硫循环中主要化合物的时间序列数据将与实验研究相结合，以解决控制过程。DMS、DMSP和DMSO将与百慕大大西洋时间序列计划的时间序列研究一起在百慕大水域进行测量。作为JGOFS计划的一部分，收集的互补化学和生物数据将提供对水华和浮游植物物种形成对DMS循环的重要性的见解。DMS及其前体和产物循环的具体过程将在协调的实验室实验中进行研究。时间序列测量和实验室实验将通过在百慕大场址进行一系列短而密集的面向过程的实地研究联系起来，以检验从时间序列和实验室工作中得出的假设。该项目的主要目标是确定和量化整个年度周期的关键控制过程。
