Abstract: BIOCOMPLEXTIY INCUBATION ACTIVITY: Earth System Regulation Through Biogenic Sulfur - Molecular to Global Interactions and Feedbacks. While individual research projects have provided insight into various processes involved in the ocean/atmosphere cycling of DMS-related research, the reality of today's funding has forced this reductionism approach. It is time for a multi-disciplined approach given the complexity, apparent non-linearity, and feed-back-type of processes involved. Some combination of intensive, process-oriented, field studies, large-scale ocean surveys and comprehensive modeling will most likely be required to advance our understanding of the DMS-climate link. Unlike previous DMS research, we propose to study simultaneously all known processes that regulate DMS concentration in seawater, leading to its sea-air flux. Also novel will be the inclusion of modeling from the outset, the ultimate goal of which will be the refinement of a DMS submodel that can be included in comprehensive and predictive global climate-system models. An ecological DMS model already exists and global scale DMS modeling has been done with GCMs [Erickson et al., 1990] and data compilations [Kettle et al., 1999]; however, much more work needs to be done, especially if a "big picture" understanding is to emerge. Developing an effective, detailed plan of research will require the coordination of a diverse set of investigators and a comprehensive review of the state of DMS science. This is a request for incubation funds to support a review of our current understanding of DMS dynamics in seawater and a workshop on DMS dynamics in seawater.

摘要：生物复合物孵化活动：通过生物硫调节地球系统 - 分子到全球的相互作用和反馈。虽然个别研究项目已经深入了解 DMS 相关研究的海洋/大气循环所涉及的各种过程，但当今资金的现实迫使这种还原论方法。考虑到所涉及过程的复杂性、明显的非线性和反馈类型，现在是时候采用多学科方法了。为了加深我们对 DMS 与气候联系的理解，很可能需要将密集的、面向过程的实地研究、大规模海洋调查和综合建模结合起来。与之前的 DMS 研究不同，我们建议同时研究调节海水中 DMS 浓度、导致其海气通量的所有已知过程。同样新颖的是从一开始就纳入建模，其最终目标将是完善 DMS 子模型，将其纳入全面的预测性全球气候系统模型中。生态 DMS 模型已经存在，并且已经使用 GCM [Erickson et al., 1990] 和数据编译 [Kettle et al., 1999] 完成了全球范围的 DMS 建模；然而，还需要做更多的工作，特别是要形成“大局”理解。制定有效、详细的研究计划需要协调不同的研究人员并对 DMS 科学状况进行全面审查。这是一项孵化资金请求，用于支持对我们目前对海水中 DMS 动力学的理解的审查以及关于海水中 DMS 动力学的研讨会。
