A Workshop for Cooperative Studies of Earth's Deep Interior

研究地球内部深处是一项多学科和国际性的活动。地球深部合作研究(CSEDI)计划是在20世纪90年代构思的，目的是促进美国研究人员在这一领域的多学科研究活动。对研究计划的最后一次更新是在2004年。过去十年的许多进展使地球深部社区重新审视CSEDI科学计划并阐明CSEDI计划的未来方向成为一个好时机。这项奖励将支持2015年1月举行的全社区讲习班。对地球内部深处的研究为我们的星球演变到目前的状态提供了关键，并向我们提供了关于它对气候、水圈和生物圈的作用和深刻影响的信息。拟议的研讨会将为围绕以下主题和副专题进行多学科讨论提供机会：(1)地球和行星的演化，到现在的路径：初始条件；行星形成；早期生命；早期构造体制；热演化。(2)地球深部引擎、现状和动力学：主要界面的结构和起源；地球发电机；地幔大尺度流动的模式；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；熔融；质量和热流。研究基础设施和社区组织在CSEDI中的作用也将被讨论。打破障碍，进行真正的多学科研究，对于提高我们对地球运行方式的理解尤为重要。拟议的研讨会将使CSEDI社区从早期职业研究人员到高级参与者充分了解深部地球研究在他们的职业生涯中是如何演变的。它不仅将评估我们的科学所处的位置，还将考虑如何最好地开展多学科科学来解决我们面临的问题。地球深处的专题对公众也有很大的吸引力，因为它们包括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有关的当今灾害等时间尺度上的行星演化。

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.
