The objective of this award is to support an international workshop at the Banff International Research Station (BIRS) on "Uncovering Transport Barriers in Geophysical Flows". The methods covered by the workshop include the topics of Lagrangian Coherent Structures (LCSs), set-theoretical approaches to Lagrangian coherence, probabilistic methods, and Lagrangian indicators motivated by ergodic theory. The goal is to bring together researchers with expertise in a variety of techniques, find common ground, and thereby develop a coordinated approach to the problem of geophysical transport. This interaction will inspire new theoretical research and advance the development of practical tools for real world application.The need to develop robust mathematical methods to identify the key dynamic structures that act as the hidden skeleton of transport in complex geophysical flows has never been more pressing, given their role in organizing climate processes (e.g. algal blooms, ozone transport) and environmental disasters (e.g. Deepwater Horizon oil spill, Icelandic volcanic ash cloud, Fukushima nuclear disaster). New tools that emerge as a result of this workshop have the potential to profoundly influence decision making strategies for the ocean, including such scenarios as the deployment of clean up equipment during an oil spill or the focus regions for a search and rescue operation. The outcomes of this workshop will be summarized in a 10-page summary document and distributed to government agencies and industry. Junior faculty and postdoctoral researchers will interact with leading faculty, developing a future pool of talent in this rapidly advancing and globally important research topic.

该奖项的目的是支持在班夫国际研究站(BIRS)举办的关于“揭示地球物理流动中的运输障碍”的国际研讨会。研讨会涉及的方法包括拉格朗日相干结构(LCS)、拉格朗日一致性的集合论方法、概率方法以及由遍历理论驱动的拉格朗日指标。其目标是将具有各种技术专长的研究人员聚集在一起，找到共同点，从而制定一种协调一致的方法来解决地球物理运输问题。这种相互作用将激发新的理论研究，并推动实际应用工具的开发。鉴于它们在组织气候过程(例如藻类水华、臭氧传输)和环境灾难(例如深水地平线漏油、冰岛火山灰云、福岛核灾难)方面的作用，确定作为复杂地球物理流动中隐藏的输送骨架的关键动态结构的必要性从未像现在这样迫切。这次研讨会产生的新工具有可能对海洋决策战略产生深远影响，包括在漏油期间部署清理设备或搜索和救援行动的重点区域等情景。研讨会的成果将汇总在一份10页的总结文件中，并分发给政府机构和工业界。初级教师和博士后研究人员将与领导教师互动，在这一快速发展和全球重要的研究主题中培养未来的人才库。
