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

0208378HubbardEarthScope是一项主要的地球科学研究计划，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(InSAR)以及补充地质和地球物理的科学信息，以了解大陆尺度的板块变形和演化。国会目前正在讨论为EarthScope倡议提供资金，作为NSF 2003财年预算的一部分。地球科学处已为符合地球范围前活动资格的项目提供了2002财政年度的资金，即一旦地球范围得到重大研究设备设施和建设(MREFC)账户的资助，将促进或使地球范围的建造、制造、安装或运行成为可能的活动。这类活动包括会议和研讨会、原型开发、选址或表征。该奖项将支持一个规划研讨会，以讨论与大平原覆盖地球范围的美国阵列组件有关的科学目标。大平原地区的地质历史包括大陆裂谷作用、海相和陆相沉积、局部盆地的形成和变形、西部第三系沉积单元的倾斜和切割、导致东西地震各向异性差异的地幔活动和地震活动。到目前为止，许多研究都是在学科范围内和地质史的个别方面进行的。显然，过去的事件之间存在联系，将工作人员聚集在一起将促进关于从地幔活动到地球表面，从前寒武纪到现在的各种话题的讨论。研讨会参与者将讨论未来可能进行的多学科合作，以解决已确定的问题，并将这些合作与美国阵列在该地区的报道联系起来。研讨会的目标是促进跨学科讨论，旨在最大限度地提高美国大平原地区阵列倡议的科学成果。*

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.***
