US Surface Ocean - Lower Atmosphere Study (SOLAS) Workshop

该奖项将支持一个关于控制表层海洋-低层大气(SOLA)区域气候相关化合物(CRC)的生物地球化学和物理过程的科学规划研讨会。该研讨会将启动美国表面海洋-低大气研究(SOLAS)科学计划的制定。美国的SOLAS将是国际SOLAS的一部分，国际SOLAS目前是IGBP、SCOR和CACGP计划的一个新的国际接口计划。国际SOLAS已经得到了SCOR和IGBP的批准。--查明关键和可解决的知识差距，以预测较低海洋大气中未来的氟氯化碳浓度。-确定哪些跨学科和多学科研究的优先次序，将有助于我们进一步了解对这一边界区域内的氯氟化碳浓度和通量的控制。--进一步制定美国研究索拉地区的科学计划，并评估这一努力将如何与其他国家和国际科学倡议相结合，如美国碳循环科学计划(CCSP)、IGBP国际全球大气化学(IGAC)项目和国际SOLAS。SOLA地区的物理、生物和化学过程影响着大气中许多CRCs的浓度。模型表明，该地区特别容易受到气候变化的影响，该地区的变化可能会影响全球CRCs的浓度。因此，预测控制性气候变化的未来水平需要更好地了解Sola的进程以及那里的进程在各种气候变化情景下将如何变化。索拉地区的许多过程在空气-水界面两侧紧密相连，必须以全面的跨学科方式进行研究。在过去十年中，有关进程的研究取得了进展，但缺乏对这些进程的整体和相互关联的看法。越来越多的证据表明生物、地质、化学和物理循环相互关联，充分证明了这种方法的必要性。一些过程，如风沙沉积的微量营养物质对表层海洋碳循环的影响，已经受到越来越多的关注。其他方面，如海洋来源的气溶胶颗粒对较低的大气氧化效率的影响刚刚变得明显起来。为了量化这些与气候有关的过程，研究表层海洋和低层大气的科学家之间必须结成伙伴关系。开发一个跨越传统学科界限的项目具有挑战性，需要社区中过去没有定期互动的调查人员提供大量意见。拟议的研讨会是促进这种互动的途径之一。与以前的跨学科努力一样，例如JGOFS，回报很高，因为科学突破往往是通过“跳出框框”(或者在这种情况下是储藏库)的思维来实现的。

ABSTRACTOCE-0111295This award will support a science-planning workshop on the biogeochemical and physical processes controlling climate relevant compounds (CRCs) in the Surface Ocean-Lower Atmosphere (SOLA) region. This workshop will initiate the development of a science plan for a US Surface Ocean-Lower Atmosphere Study (SOLAS). US SOLAS will be part of the international SOLAS, which is currently planned as a new international interfacial program by the IGBP, SCOR and CACGP. The international SOLAS has already been approved by SCOR and IGBP. This workshop will be structured around several interelated fundamental science issues in ocean/atmosphere biogeochemical coupling:-- The Surface Ocean-Lower Atmosphere Sulfur Cycle-- Radiation and Photochemistry in the Surface Ocean-Lower Atmosphere-- Boundary Layer Dynamics of CO2 and other climate relevant gases-- Atmospheric Connections with the Marine Nitrogen Cycle-- Boundary Layer Physics Through discussions in the five science issue areas above, the overall objectives of the workshop will be to: -- Summarize recent advances in quantifying fluxes of CRCs in the SOLA region. -- Identify critical and addressable knowledge gaps to predict future concentrations of CRCs in the lower marine atmosphere. -- Prioritize which inter- and multi-disciplinary studies will further our understanding of controls on the concentrations and fluxes of CRCs in this boundary region. -- Further the development of a US science plan for study of the SOLA region and evaluate how such an effort would interface with other national and international science initiatives such as the U.S. Carbon Cycle Science Plan (CCSP), the IGBP International Global Atmospheric Chemistry (IGAC) project and the international SOLAS. The atmospheric concentrations of many CRCs are affected by physical, biological, and chemical processes in the SOLA region. Models suggest that this region is particularly susceptible to climate change, and that changes in this region can affect global concentrations of CRCs. Forecasting future levels of the CRCs thus requires better knowledge of processes in the SOLA and how the processes there will change under various climate change scenarios. Many processes in the SOLA region are closely linked on both sides of the air-water interface and must be investigated in a comprehensive interdisciplinary fashion. Advances have been made over the last decade in the study of the relevant processes, but a holistic and interlinking view of these processes has been lacking. The need for such an approach has been amply documented by increasing evidence of the interconnectivity of biogeochemical and physical cycles. Some processes, such as the effect of aeolian deposition of trace nutrients on the surface ocean's carbon cycle, have received increasing attention. Others, such as the effect of ocean-derived aerosol particles on lower atmosphere oxidation efficiency are just becoming apparent. To quantify these climate-relevant processes a partnership between scientists investigating the surface ocean and lower atmosphere is necessary. Developing a program that crosses traditional disciplinary boundaries is challenging and requires significant community input from investigators who have not routinely interacted in the past. The proposed workshop is one avenue to foster such interactions. As with previous interdisciplinary efforts, such as JGOFS, the returns are high as scientific breakthroughs are often accomplished by thinking "outside the box"[or in this case reservoir].
