Using and Evaluating Strainmeter Data - A Pre-EarthScope Initiative

agnewearthscope是一项重要的地球科学研究计划，它将整合来自地震学（US Array）、大地测量学（板块边界观测站）、地下采样和测量（SAFOD）、遥感（InSAR）以及互补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，美国国会正在讨论为“地球镜”项目提供资金，作为美国国家科学基金会2003财年预算的一部分。地球科学部已将2002财年的资金用于符合EarthScope前期活动资格的项目，即在获得MREFC（主要研究设备设施和建设）账户资助后，将促进或使EarthScope的建造、制造、安装或操作成为可能的活动。这些活动包括会议和研讨会、原型开发、选址或特征描述。该奖项将提供资金支持一些活动，这些活动将使作为“地球范围”板块边界观测站（PBO）组成部分的大量应变仪的数据更有用，并得到更广泛的应用。目前，只有少数调查人员使用应变仪的数据，主要是那些安装和操作仪器的人；对于更大的地球物理团体来说，这些数据似乎有点神秘，就像GPS数据最初的样子一样。首席研究员将开展多项活动，为感兴趣的研究人员“揭开”应变仪数据的神秘面纱，从而使这些数据更容易获得。这些活动包括教学和研究工作，所有这些活动都利用了pi在应变测量和解释领域公认的专业知识。具体工作包括四项活动：1)制定应变仪指南；2)加工软件的开发；3)促进数据可用性；4)阵列设计的数据表征。＊＊＊

0207863AgnewEarthScope 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 provides funds to support activities which will make the data from the large number of strainmeters to be installed as part of the Plate Boundary Observatory (PBO) component of EarthScope more useful, and more widely used. At present, strainmeter data are used only by a small number of investigators, primarily those who install and operate the instruments; to the larger geophysical community these data seem somewhat mysterious, rather as GPS data originally did. The Principal Investigator will undertake several activities which should "demystify" strainmeter data for interested researchers, and thus make these data much more generally accessible. These activities include both didactic and research efforts, all drawing on the PIs recognized expertise in the area of strain measurement and interpretation. The specific work to be undertaken includes four activities: 1) the development of a strainmeter guide; 2) the development of processing software; 3) facilitating data availability; and 4) data characterization for array design. ***
