Support for 20th International Workshop on Electromagnetic Induction in the Earth, to be held September 18-24, 2010 in Giza, Egypt

该项目旨在为参加2010年9月18日至24日在埃及吉萨举行的第20届地球电磁感应国际研讨会的学生、年轻研究人员(包括博士后科学家和年轻教员)提供部分注册、旅费和生活费。这一两年一次的研讨会由国际地磁学和大气学会(IAGA)第I-2工作组赞助，已成为世界各地研究人员会面和讨论EM地球物理学新发展的主要场所。由于导电性对温度、流体、矿石矿物和岩石类型的敏感性，电磁测量提供了了解地球的独特视角。这种敏感性使EM方法在从非常近的地表到地幔深处处理应用科学和基础科学问题的广泛调查中有用。例如，EM方法长期以来一直是采矿业青睐的勘探工具，在石油勘探中发挥着越来越重要的作用。EM有太多的近地表应用：一般地质测绘、废弃地评估、含水层测绘和脆弱性研究、建筑材料勘探、建筑和公用事业调查，以及未爆弹药的探测和识别。导电性对流体的敏感性极大地影响了岩石的强度，这也使EM成为更大规模研究地球深处的结构、动力学和演化以及评估火山和地震灾害的重要工具。该项目将使美国EM入门社区受益，通过增加来自美国的学生和早期职业研究人员参与这次国际会议，帮助美国研究人员发展国际联系，最终导致世界各地的合作项目，并通过促进软件、数据和结果的国际交流。NSF的支持也被用来利用来自行业的额外支持。旅行支持的个人奖励由工作组财政支持社区从学生和职业早期研究人员提交的申请中确定。这次研讨会由地球物理、地球范围和大陆动力学项目资助。

This project is to provide funds to partially cover registration, travel, and living expenses for students, young researchers (including post doctoral scientists, and young faculty), to attend the 20th International Workshop on Electromagnetic (EM) Induction in the Earth in Giza, Egypt on September, 18-24, 2010. This biennial workshop, which is sponsored by Working Group I-2 of the International Union of Geomagnetism and Aeronomy (IAGA), has become the premier venue for researchers around the world to meet and discuss new developments in EM geophysics. EM measurements provide a unique view into the Earth because of the sensitivity of electrical conductivity to temperature, fluids, ore minerals, and rock type. This sensitivity makes EM methods useful in a wide range of investigations, addressing both applied and basic science questions, from the very near surface to the deep mantle. For example, EM methods have long been the favored tool for exploration in the mining industry, and they play an increasingly important role in petroleum exploration. A plethora of near-surface applications exist for EM: general geological mapping, waste site assessment, aquifer mapping and vulnerability studies, exploration for construction materials, building and utility investigation, and UXO detection and discrimination. The sensitivity of conductivity to fluids, which strongly influence rock strength, also makes EM an essential tool for larger scale investigations of the structure, dynamics, and evolution of the deep Earth, and for assessing volcanic and seismic hazards. The project will benefit the US EM induction community, by increasing participation of students and early career researchers from the US at this international meeting, by helping US researchers to develop the international contacts that will ultimately lead to collaborative projects around the world, and by promoting international exchange of software, data, and results. NSF support is also being used to leverage additional support from industry. Individual awards for travel support are determined by the working group financial support community, from applications submitted by students and early-career researchers.This workshop was funded by the Geophysics, EarthScope, and Continental Dynamics Programs.
