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、量化和参数化控制海气交换的混合和地球化学过程，这是调查海洋温室气体通量的核心。虽然全球海洋作为人类活动产生的二氧化碳的主要汇的作用已得到公认，但全球变暖对驱动海气气体交换的机制的影响是不确定性的一个主要来源。因此，必须提高我们对碳吸收的物理和地球化学机制及其对不断变化的环境条件的敏感性的理解。社区交流最新研究成果的机会将促进我们对空气-水气体交换的认识。该奖项为学生，博士后研究员和早期职业科学家提供旅行支持，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转移国际研讨会。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，以满足和与气体传输社区的广泛领先的科学家互动。社区本身也将受益于参与和培养下一代科学家的机会。一个专门从事会议记录的在线开放获取服务将被用来提供广泛和及时的研究报告的分布。研讨会定期汇集国际科学和工程界调查的机制，参数化，和影响的气体转移在水面。重点是控制气体通量的物理和地球化学过程，包括风、波浪破碎和水流引起的湍流以及自然和人为表面活性剂的影响。这些是控制热量和动量通量的相同机制，因此社区中的许多人参加了会议，研究在海洋表面或附近发生的各种空气和水侧混合过程。专题讨论会涵盖的主题包括现场，实验室和模拟调查的物理管理的空气-水传输，开发和测试参数化用于全球气候模型，以及映射和评估的全球分布的空气-海洋二氧化碳通量。除了这些核心议题外，2015年研讨会还将包括二氧化碳吸收增加导致的海洋酸化以及海冰范围减少对极地地区气体转移的影响。将包括来自地球科学（海洋学、大气科学、水文学）、工程学科（土木、机械、化学、环境）和基础科学的研究人员关于气水边界输送和跨气水边界输送的所有方面的发言。
