12th International Workshop on Modeling of Mantle Convection and Lithospheric Dynamics

该提案要求部分支持美国科学家前往2011年8月20日至8月25日在德国格罗斯顿举行的第12届地幔对流和岩石圈动力学建模国际研讨会（IW12）。预计约有22名与会者将从美国参加会议，其中包括主讲人Mike Gurnis、Laurent Montesi、Barabara Romanowicz和Shun Karato。会议的主要目标是(a)详细讨论地球动力学建模的科学和技术方面，以及与邻近学科的互动；(b)在非正式环境中向学生和博士后介绍当前地球动力学研究的领先领域；(c)跨学科和国际合作。受邀的主题演讲将集中在许多领域，包括岩石圈的流变学和动力学，岩石圈和软流圈之间的相互作用，熔体产生及其对地幔动力学的影响，化学非均质性，其他行星的对流和岩石圈动力学，早期地球动力学，新的数值技术和基准。地球动力学模型利用力学原理回答了关于地球和行星内部过程、热结构和演化的基本问题。在20世纪后半叶，地球动力学领域的合作研究有了巨大的增长。再加上岩石和矿物物理学、地震学和大地测量学等领域令人兴奋的新发现，地球动力学为地球和行星科学中的一些基本问题提供了答案。本次研讨会为地球动力学的各个分支学科以及来自其他领域的专家提供了一个互动的舞台，提供了最新的发展信息。这是一个相对集中的小型会议，旨在促进跨地域科学家之间的合作。对于早期职业参与者，本次研讨会将提供一个独特的机会来获取新的信息，形成一个早期职业科学家的队列，鼓励未来的合作。非正式的会议和会议，包括与社区资深成员的深入讨论，也将有利于研究生和博士后参与者。

This proposal requests for partial support for US-based scientists to travel to the 12th International Workshop on Modeling of Mantle Convection and Lithospheric Dynamics (IW12), in Gross Dolln, Germany, from August 20th to August 25th, 2011. Approximately 22 participants, including key note speakers Mike Gurnis, Laurent Montesi, Barabara Romanowicz, and Shun Karato, are anticipated to attend the conference from the US. The main objectives of the Conference are (a) detailed discussions on scientific and technical aspects of geodynamic modeling, and interaction with neighboring disciplines, (b) introducing students and postdocs in an informal environment to the current leading areas of geodynamic research and (c) Interdisciplinary and international Collaboration. Invited keynote speeches will concentrate on a number areas including the rheology and dynamics of the lithosphere, interaction between the lithosphere and the asthenosphere, melt production and its effect on mantle dynamics, chemical heterogeneity, convection and lithospheric dynamics in other planets, early Earth dynamics, new numerical techniques, and benchmarks.Geodynamic models answer fundamental questions on the internal processes, thermal structure, and evolution of Earth and planets using the principals of mechanics. Over the last half of the 20th century, there has been a tremendous growth in collaborative research topics in geodynamics. Coupled with exciting new discoveries in the areas of rock and mineral physics, seismology, and geodesy, geodynamics has provided answers to some fundamental questions in Earth and planetary sciences. This workshop provides an arena for interaction among various sub disciplines of geodynamics as well as experts from other fields providing the latest information on the developments. This is a relatively focused, small scale conference that fosters collaboration between scientists across geographical boundaries. For the early career participants, this workshop will provide a unique opportunity to acquire new information, form a cohort of early career scientists, encouraging future collaboration. The informal set up of the conference and sessions involving in-depth discussion with senior members of the community will also be beneficial for the graduate student and post- doctoral participants.
