The International Symposium on Gas Transfer at Water Surfaces has occurred roughly every five years since 1983 and is organized and hosted on a voluntary basis by members of the community. The Symposium objectives to understand, quantify, and parameterize the mixing and biogeochemical processes governing air-sea gas exchange are central to the investigation of ocean fluxes of greenhouse gases. Although the role of the global ocean as a major sink of anthropogenic carbon dioxide is well established, the impact of global warming on the mechanisms that drive air-sea gas exchange is a major source of uncertainty. Thus it is essential to improve our understanding of the physical and biogeochemical mechanisms responsible for carbon uptake and their sensitivity to changing environmental conditions. The opportunity for the community to exchange recent research results will advance our knowledge of air-water gas exchange. This award provides travel support for students, postdoctoral fellows, and early career scientists to attend the 7th International Symposium on Gas Transfer at Water Surfaces in Seattle, WA on 18-21 May 2015. Attendance by students, postdocs, and early career scientists will provide a valuable opportunity to meet and interact with a wide range of leading scientists in the gas transfer community. The community itself will also benefit by the opportunity to engage and entrain the next generation of scientists. An on-line open access service that specializes in conference proceedings will be used to provide a wide and timely distribution of the reported research.The Symposium periodically brings together the international scientific and engineering community investigating the mechanisms, parameterizations, and implications of gas transfer at water surfaces. The focus is on the physical and biogeochemical processes that govern gas flux, which include turbulence due to wind, wave breaking, and currents and the effect of natural and anthropogenic surfactants. These are the same mechanisms that govern the flux of heat and momentum and thus the conference is attended by many in the community studying a wide range of air- and water-side mixing processes that occur at or near the ocean surface. The topics covered by the Symposium encompass field, laboratory, and modeling investigations of the physics governing air-water transfer, development and testing of parameterizations for use in global climate models, and mapping and assessment of the global distribution of air-sea Carbon Dioxide fluxes. In addition to these core topics, the 2015 Symposium will include the topics of ocean acidification due to increased Carbon Dioxide uptake and the impact of reducing sea-ice extent on gas transfer in Polar Regions. Presentations by researchers from the geosciences (oceanography, atmospheric sciences, hydrology), engineering disciplines (civil, mechanical, chemical, environmental), and the basic sciences related to all aspects of transport to, and transfer across, gas-water boundaries will be included.

自1983年以来，水面气体转移国际研讨会大约每五年举行一次，由社区成员自愿组织和主办。研讨会的目标是了解、量化和参数化控制空气-海洋气体交换的混合和生物地球化学过程，这是研究海洋温室气体通量的核心。尽管全球海洋作为人为二氧化碳主要汇的作用已得到充分确认，但全球变暖对推动海气交换机制的影响仍是一个主要的不确定性来源。因此，有必要提高我们对碳吸收的物理和生物地球化学机制及其对变化环境条件的敏感性的理解。这个交流最新研究成果的机会，将增进我们对空气-水-气交换的认识。该奖项为参加2015年5月18日至21日在华盛顿州西雅图举行的第七届水面气体传输国际研讨会的学生、博士后研究员和早期职业科学家提供旅费支持。学生，博士后和早期职业科学家的出席将提供一个宝贵的机会，与气体传输界的众多领先科学家会面和互动。社区本身也将受益于参与和培养下一代科学家的机会。专门提供会议记录的在线开放获取服务将用于广泛和及时地分发报告的研究。研讨会定期汇集国际科学界和工程界，研究水面气体传输的机制、参数化和影响。重点是控制气体通量的物理和生物地球化学过程，其中包括由于风，波浪破碎和洋流引起的湍流以及自然和人为表面活性剂的影响。这些都是控制热量和动量通量的相同机制，因此，许多社区的人参加了会议，研究发生在海洋表面或海洋表面附近的空气和水的混合过程。专题讨论会涵盖的主题包括对控制空气-水转移的物理进行实地、实验室和模拟调查，开发和测试用于全球气候模式的参数化，以及绘制和评估海气二氧化碳通量的全球分布。除了这些核心议题之外，2015年的研讨会还将包括由于二氧化碳吸收增加而导致的海洋酸化以及海冰面积减少对极地地区气体转移的影响等主题。来自地球科学（海洋学、大气科学、水文学）、工程学科（土木、机械、化学、环境）以及与气水边界运输和跨气水边界转移有关的所有方面的基础科学的研究人员的演讲将被包括在内。
