A Workshop for Cooperative Studies of Earth's Deep Interior

地球深处的研究是一项多学科的国际活动。地球深层内部合作研究 (CSEDI) 计划于 20 世纪 90 年代构思，旨在促进美国研究人员在该领域的多学科研究活动。该研究计划的最后一次更新是在 2004 年进行的。过去十年中取得的众多进展使现在成为地球深处社区重新审视 CSEDI 科学计划并阐明 CSEDI 计划未来方向的好时机。该奖项将支持 2015 年 1 月举办的全社区研讨会。对地球深层内部的研究为我们的星球演化到现在的状态提供了关键，并让我们了解其对气候、水圈和生物圈的作用和深刻影响。拟议的研讨会将为围绕以下主题和副主题进行多学科讨论提供机会：（1）地球和行星的演化，通往现在的道路：初始条件；行星形成；早期生活;早期构造制度；热演化。(2) 地球深部发动机，现状与动力学：主要界面的结构与起源；地球发电机；地幔中大规模流动的模式；核心结构。（3）对气候/水圈/生物圈和未来的深刻影响：挥发物的作用；熔化;质量和热通量。还将讨论研究基础设施和社区组织在 CSEDI 中的作用。打破真正进行多学科研究的障碍对于提高我们对地球运行方式的理解尤为重要。拟议的研讨会将吸引 CSEDI 社区各个层面的参与，从早期职业研究人员到高级参与者，充分了解地球深处研究在其职业生涯中的发展情况。它不仅会评估我们的科学状况，还会考虑如何最好地进行多学科科学来解决我们面临的问题。地球深处的主题也对公众具有强烈的吸引力，因为它们包括时间尺度上的行星演化，从地球的吸积到地磁场的起源、早期生命的发展、大型火成岩省的形成以及与火山过程和气候变化相关的当今危害。

Study of Earth's deep interior is a multidisciplinary and international activity. The Cooperative Studies of Earth's Deep Interior (CSEDI) program was conceived in the 1990s to facilitate multidisciplinary research activities in this area by US researchers. The last update to the research plan was produced in 2004. Numerous advances over the past decade make this a good time for the deep Earth community to revisit the CSEDI science plan and articulate future directions for the CSEDI program. This award will support a community-wide workshop in January 2015. Studies of Earth's deep interior provide the key to the evolution of our planet to its present state, and inform us about its role and deep impacts on climate the hydrosphere and biosphere. The proposed workshop will provide the opportunity for multidisciplinary discussions around the following themes and subtopics:(1) Evolution of Earth and Planets, Path to the Present: Initial Conditions; Planetary Formation; Early Life; Early Tectonic Regimes; Thermal evolution.(2) Deep Earth Engine, Present state and dynamics: Structure and Origin of Major interfaces; Geodynamo; Pattern of large scale flow in the Mantle; Core structure.(3) Deep Impacts on Climate/Hydrosphere/ Biosphere and the Future: Role of volatiles; melt; mass and heat fluxes.The role of research infrastructure and community organizations in CSEDI will also be discussed.Breaking down barriers to doing truly multidisciplinary research is particularly important for improving our understanding of the way the Earth works. The proposed workshop will engage the CSEDI community at all levels from early career researchers to senior participants fully aware of how deep earth research has evolved over their careers. It will not only evaluate where our science is, but will also consider the question of how best to do multidisciplinary science to solve the problems that face us. Deep Earth topics also have a strong appeal to the public, since they include planetary evolution on time scales ranging from accretion of the Earth through origin of the geomagnetic field, development of early life, formation of Large Igneous Provinces and present day hazards related to volcanic process and climate change.
