Workshop: Uncovering Transport Barriers in Geophysical Flows; Banff International Research Station (BIRS), Banff, Alberta; 22 to 27 September 2013

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”的国际讲习班。研讨会涵盖的方法包括拉格朗日相干结构（LCS），拉格朗日相干性的集合理论方法，概率方法和拉格朗日指标遍历理论的主题。目标是汇集在各种技术方面具有专门知识的研究人员，找到共同点，从而制定一个协调一致的方法来解决地球物理迁移问题。这种相互作用将激发新的理论研究，并推动为真实的世界应用开发实用工具。鉴于关键动态结构在组织气候过程中的作用，开发强有力的数学方法来识别在复杂地球物理流中充当运输隐藏骨架的关键动态结构的需求从未像现在这样紧迫（如藻华、臭氧迁移）和环境灾害（如深水地平线漏油、冰岛火山灰云、福岛核灾难）。这次研讨会产生的新工具有可能深刻影响海洋决策战略，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。研讨会的成果将在一份10页的摘要文件中总结，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先的教师互动，在这个快速发展和全球重要的研究课题中培养未来的人才库。

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.
