Mattioli1441122This grant will support a focused three day workshop in Colorado in early fall 2014. The purpose of the workshop is to bring together various stakeholders to discuss the future of the Plate Boundary Observatory (PBO) continental scale geodetic network in the U.S. PBO consists of approximately 1100 continuously operating Global Positioning System receivers installed across the U.S. but with increased density in the Western U.S. near the active plate margin of the North American plate. Here, crustal deformation rates are high and earthquakes are concentrated along the San Andreas and associated transform faults. Offshore the Pacific Northwest and southern Alaska ocean crust is subducted beneath the North American plate leading to active volcanic processes in the Cascades and Aleutians and where large tsunamigenic earthquakes have been recorded in the historical record. PBO also includes other geodetic sensing modalities including borehole strainmeters (BSM) and seismometers, long baseline laser strain meters (LSM), tiltmeters and surface meteorological measurements. Geodetic observations are recorded at a range of frequencies and some 400 of the 1100 GPS stations record at high rates (1 Hz) and transmit data in real time. All PBO data and data products are archived centrally UNAVCO, Inc. (www.unavco.org) and are freely available via internet web access. PBO data products are used to address a wide range of scientific and technical issues across North America. A large US and international community of surveyors and civil engineers access PBO data streams, software, and other on-line resources daily. The western US and Alaska, where over 95% of the PBO sensor assets are located, have experienced and will continue to experience significant and potentially damaging geophysical events like earthquakes, volcanic eruptions, and tsunamis. The science facilitated by PBO provides first-order constraints on geophysical processes to support hazards mapping and zoning and for earthquake early warning applications currently under development. Under a new NSF-UNAVCO, Inc. five-year Cooperative Agreement, PBO along with globally distributed geodetic infrastructure used for precise positioning via GPS and to support satellite and spacecraft orbital positioning, are now managed as part of the so-called GAGE facility (Geodesy Advancing Geosciences and EarthScope). In FY 2013, budget challenges led to a directed cut to the baseline GAGE support from NSF from operational costs incurred in FY 2012 and previous. Thus, the workshop will seek to identify the longer term ramifications of that rebaselining and how scientific and other priorities will help define what components of PBO, in particular, are at risk of being terminated in the near future under the period of the GAGE five year Cooperative Agreement (2013-2018). The workshop will support a meeting of a number of scientific and technical leaders with a wide variety of scientific interests, representatives from the commercial sector who either have current products or business models based on free and open access to the Plate Boundary Observatory (PBO) geodetic facility data and data products, or who may have an interest in developing new business or products based on PBO assets and streams in the future, and relevant federal and state agency representatives. The workshop will result in a report and web resources encapsulating community-vetted recommendations. ***

The purpose of the workshop is to bring together various stakeholders to discuss the future of the Plate Boundary Observatory (PBO) continental scale geodetic network in the U.S. PBO consists of approximately 1100 continuously operating Global Positioning System receivers installed across the U.S. but with increased density in the Western U.S. near the active plate margin of the North American 盘子。 在这里，地壳变形率很高，地震集中在圣安德烈亚斯（San Andreas）以及相关的变换断层。 海上太平洋西北和阿拉斯加南部的海角在北美板块下方俯冲，导致喀斯喀特山脉和阿留申者的活跃火山过程，并在历史记录中记录了大型海啸地震。 PBO还包括其他大地传感方式，包括钻孔应变器（BSM）和地震仪，长基线激光应变仪（LSM），倾斜度和表面气象测量。 在一系列频率和1100 GPS电台的大约400个以高率（1 Hz）记录的大约400个测量观测值，并实时传输数据。 所有PBO数据和数据产品均归类为中央UNAVCO，Inc。（www.unavco.org），并且可以通过Internet Web访问免费获得。 PBO数据产品用于解决北美各种科学和技术问题。美国和国际大型测量师和土木工程师社区每天访问PBO数据流，软件和其他在线资源。美国和阿拉斯加西部有超过95％的PBO传感器资产所在，并将继续经历并将继续经历重大且可能破坏的地球物理事件，例如地震，火山喷发和海啸。 PBO促进的科学提供了对地球物理过程的一阶限制，以支持危害映射和分区以及目前正在开发的地震预警应用程序。根据新的NSF-Unavco，Inc。五年合作协议，PBO以及用于通过GPS进行精确定位的全球分布的大地测量基础架构，并支持卫星和航天器轨道定位，作为所谓的Gage设施（地理上的地球科学和泥土）的一部分进行管理。 在2013财年，预算挑战导致了NSF的基准计量规支架的指导，该基准量规定因2012财年及以前而产生的运营成本。 因此，该研讨会将寻求确定该重新考虑的长期后果，以及科学和其他优先事项将如何有助于定义PBO的哪些组成部分，尤其是在五年合作协议（2013-2018）期间，在不久的将来被终止的危险。 该研讨会将支持许多具有各种科学利益的科学和技术领导者的会议，来自商业领域的代表，他们要么基于自由和开放式访问Plate Boundare Persectervatory（PBO）地理设施数据和数据产品，或者可能对基于PBO Asset和Sprebs的New Business或Spreats在未来的Fedutress和Secorts Anipers和Secords Agents和Secords and Actorn和Secorlant和Secorlant和Secorlant和相关的代理机构中，他们可能对板块边界观测值（PBO）地球界数据和数据产品产生兴趣。 研讨会将导致报告和网络资源封装社区审查的建议。 ***
