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班夫国际研究站（BIRS）关于“揭示地球物理流动中的运输障碍”的国际研讨会。研讨会涵盖的方法包括拉格朗日相干结构（LCSs）、拉格朗日相干的集合理论方法、概率方法和由遍历理论驱动的拉格朗日指标。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，从而开发出解决地球物理传输问题的协调方法。这种互动将激发新的理论研究，并推动实际应用工具的发展。考虑到它们在组织气候过程（如藻类繁殖、臭氧运输）和环境灾难（如深水地平线石油泄漏、冰岛火山灰云、福岛核灾难）中的作用，开发强大的数学方法来识别在复杂地球物理流动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迫切。本次讲习班产生的新工具有可能深刻影响海洋决策战略，包括在溢油期间部署清理设备或搜索和救援行动重点区域等情况。这次讲习班的成果将总结成一份10页的摘要文件，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上发展未来的人才库。

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.
