Participant Support for 2004 International SEDI Meeting

我们请求的资金将用于支付第八届地球深部研究研讨会(SEDI)的参会费。会议将于2004年7月4日至9日在德国加米施帕滕基兴举行。Knowledge Merit Sedi是一家致力于研究地球内部深处的国际科学组织。SEDI的最终目标是增强对地球深部过去的演化和当前的热、动力和化学状态的了解，以及对地球内部对地球表面观察到的结构和过程的影响的了解。“深部内部”通常被认为是核心和下地幔，但人们的兴趣可能延伸到表面，例如，在研究地幔羽流或下降的岩石圈板块的动力学方面。SEDI感兴趣的科学问题和问题包括地磁发电机和长期变化，古地磁和地球深部的演化，外核的组成，结构和动力学，发电机能量学，内核的结构，核冷却和核幔边界区域，核-地幔边界形状，耦合和地球自转，下地幔：结构，对流和羽流，深层地球化学储层的性质和位置，等等。这项建议将通过在一个相对较小的研讨会式的会议上促进与各级研究人员的对话，为美国研究生和年轻研究人员的跨学科教育做出贡献。SEDI的结构本质上是跨学科的，为在一系列主题上进行内部和国际合作提供了许多机会，有助于我们对地球深处的了解。

We request funds that will be used to contribute to participant costs for the 8th symposium on Study of Earth's Deep Interior (SEDI). The meeting will be held in Garmisch Partenkirchen, Germany from July 4-9, 2004. Intellectual Merit SEDI is an international scientific organization dedicated to the Study of the Earth's Deep Interior. The ultimate goal of SEDI is an enhanced understanding of the past evolution and current thermal, dynamical, and chemical state of the Earth's deep interior and of the effect that the interior has on the structures and processes observed at the surface of the Earth. The 'deep interior' is generally considered to be the core and lower mantle, but interest may extend to the surface, for example, in the study of mantle plumes or dynamics of descending lithospheric slabs. The scientific questions and problems of interest to SEDI include the geomagnetic dynamo and secular variation, paleomagnetism and the evolution of the Earth's deep interior, composition, structure and dynamics of the outer core, dynamo energetics, structure of the inner core, core cooling and the core-mantle boundary region, core-mantle boundary shape, coupling and the rotation of the Earth, lower mantle: structure, convection and plumes, nature and location ofdeep geochemical reservoirs, etc. Broader Impact This proposal will contribute to interdisciplinary education of US graduate students and young researchers by fostering dialog with researchers at all levels at a relatively small workshop style meeting. The structure of SEDI is intrinsically interdisciplinary, providing many opportunities for intra- and international collaborations on a range of topics that contribute to our understanding of the deep earth.
