USArray and the Great Plains: A Pre EARTHSCOPE Workshop Proposal (February 2003)

0208378 HubbardEarthScope是一项重大的地球科学研究计划，它将整合来自地震学（美国阵列）、大地测量学（板块边界观测站）、地下采样和测量（SAFOD）、遥感（干涉合成孔径雷达）以及补充地质学和地球物理学的科学信息，以了解大陆尺度的板块变形和演化。目前，国会正在讨论为地球观测计划提供资金的问题，作为国家科学基金会2003财政年度预算的一部分。 地球科学司已将2002财政年度的资金提供给符合EarthScope前活动条件的项目，即一旦由MREFC（主要研究设备设施和建设）账户供资，将促进或使EarthScope的建设、制造、安装或运行成为可能的活动。 这些活动包括会议和讲习班、原型开发、选址或定性，该奖项将支持一个规划讲习班，讨论与地球镜美国阵列组成部分大平原覆盖范围有关的科学目标。 大平原地区的地质历史包括大陆裂谷、海相和非海相沉积、局部盆地形成和变形、西部第三纪沉积单元的倾斜和切割、地幔活动导致东部和西部地区地震各向异性的对比以及地震活动。 迄今为止，大部分研究都是在学科范围内和地质历史的各个方面进行的。 显然，过去的事件之间存在着联系，将工作人员聚集在一起将促进对从地幔活动到地球表面以及从前寒武纪到现在的主题的讨论。 研讨会的参与者将讨论未来可能的多学科合作，以解决已确定的问题，并可以将这些合作与该地区的USAray覆盖面相结合。 研讨会的目标是促进跨学科的讨论，旨在最大限度地提高大平原地区USAray计划的科学收益。

0208378HubbardEarthScope is a major earth science research initiative that will integrate scientific information derived from seismology (US Array), geodesy (Plate boundary Observatory), subsurface sampling and measurement (SAFOD), remote sensing (InSAR), and complementary geology and geophysics to understand continental scale plate deformation and evolution. Funding for the EarthScope initiative is currently being discussed in Congress as part of NSF's FY 2003 budget. The Division of Earth Sciences has made FY 2002 funds available for projects that qualify as pre-EarthScope activity, i.e. activities that will facilitate or enable the construction, fabrication, installation or operation of EarthScope once it is funded under the MREFC (Major Research Equipment Facilities and Construction) account. Such activities include meetings and workshops, prototype development, site selection or characterization.This award will support a planning workshop to discuss scientific objectives related to the Great Plains coverage of the USArray component of EarthScope. The Great Plains region has had a geologic history that includes continental rifting, marine and non-marine sedimentation, localized basin formation and deformation, tilting and incision of Tertiary sedimentary units in the west, mantle activity resulting in contrasting seismic anisotropy between eastern and western regions, and earthquake activity. To date, much of the research has been done within disciplines and on individual aspects of the geologic history. Clearly there are relationships between past events, and bringing workers together will foster discussion about topics ranging from mantle activity to the Earth's surface and from the Precambrian to the present. The workshop participants will discuss possible multidisciplinary future collaborations to address identified questions and can interface these collaborations with the USArray coverage in the region. The goal of the workshop is to foster interdisciplinary discussion that is aimed at maximizing the scientific gain from the USArray initiative in the Great Plains region.***
