0607782MattioliThis award provides renewal support for the CALIPSO Project (Caribbean Andesitic Lava Island Precision Seismo-geodetic Observatory) on Montserrat, WI. The ultimate goal of this project is to investigate the dynamics of the entire magmatic system of Soufriere Hills Volcano (SHV), and to enhance our generic understanding of andesitic magma dynamics.The project was initiated in 2002 with drilling and installation of four high-sensitivity borehole (200-m deep) seismic and ground deformation (strainmeter, tiltmeter, cGPS) stations around the SHV. This is the first and only such instrumented borehole network at any andesite volcano. The project involves six US institutions (Arizona State U, U Arkansas, Carnegie Institution of Washington, Cornell, Duke, Penn State), Bristol and Leeds universities in the UK, and the Montserrat Volcano Observatory (MVO). Principal funding (ca. 2 million USD) was from NSF (Continental Dynamics, and I/F), with a contribution from UK. The installations were completed by 2004, and important instrumental data have been recovered, including those from a prodigious lava dome collapse in 2003, explosions in 2003-5, and restarted dome growth 2005 (Mattioli et al., 2004, 2005; Voight et. al., 2005). The PI's efforts to date have focused necessarily on facility and data transfer issues, but their initial research on the data promises quite important insights on the magmatic system (Voight et al. 2005). The PIs argue that the data being collected are of unprecedented value, and their analysis is merited on scientific grounds as well as to support the considerable investment NSF has made in developing the CALIPSO facility. A new direction added to the CALIPSO Project is the SEA-CALIPSO experiment, an extension involving a Seismic Experiment with Airgun- source. This is an 'onshore - offshore' seismic experiment to image the magma chamber and deep crust underlying the SHV on Montserrat. The data acquisition phase of this experiment will be carried out in 2007, with combined support of NSF (Geophysics) and the National Environmental Research Council (NERC) of the UK (see correspondence). Support for the analysis and modeling research phase for the data acquired in SEA-CALIPSO is being provided in this award.Specifically, this award provides support for: (1) analyses of borehole (and ancillary surface instrument) data involving strainmeter, cGPS, tilt, seismic and other datasets, including calibrations and modeling efforts, to deduce the physical characteristics of the magma system and its perturbations (e.g. new magma influx, explosions); (2) complete analysis, modeling and interpretation of SEA-CALIPSO data (airgun and earthquake data set recorded by ~100 PASSCAL seismic recorders for a 3-4 month period centered on the airgun survey) to generate tomographic and reflection imaging of the magmatic system;(3) linkage of the borehole observatory analyses, tomographic imaging information, and deformation and fluid mechanic modeling;(4) timely team workshops for coordinated planning of the research; (5) educational outreach, and communication of research results.

0607782 Mattiolithis Award在威斯康星州蒙特塞拉特（Montserrat）上对Calipso Project（加勒比海安第斯山脉熔岩岛Precision Seismo-Geodetic obsvoration）提供了更新支持。该项目的最终目标是研究Soufriere Hills火山（SHV）整个岩浆系统的动力学，并增强我们对安第斯山脉岩浆动力学的一般理解。井眼（200米深）地震和地面变形（应变计，倾斜计，CGPS）站，周围位于SHV周围。 这是任何安山岩火山的第一个也是唯一的仪器井网。 该项目涉及六个美国机构（Arizona State U，U阿肯色州，华盛顿卡内基研究所，康奈尔，杜克大学，宾夕法尼亚州立大学），布里斯托尔和利兹大学，以及蒙特塞拉特火山天文台（MVO）。主要资金（约200万美元）来​​自NSF（大陆动力和I/F），并由英国捐款。这些设施已于2004年完成，并且已经恢复了重要的仪器数据，其中包括2003年杂乱无章的熔岩圆顶崩溃的仪器数据，2003 - 5年的爆炸以及重新启动了Dome Dome 2005（Mattioli等，2004，2005; Voight等。 Al。，2005）。 PI迄今为止的努力必须集中在设施和数据传输问题上，但是他们对数据的最初研究有望在岩浆系统上具有非常重要的见解（Voight等，2005）。 PI认为收集的数据具有前所未有的价值，其分析是基于科学的理由，并支持NSF在开发Calipso设施中所做的大量投资。 Calipso项目添加的新方向是Sea-Calipso实验，这是一种涉及气枪来源的地震实验的扩展。这是一个“陆上”地震实验，以对岩浆腔和蒙特塞拉特（Montserrat）上SHV的深层地壳进行想象。 该实验的数据采集阶段将于2007年在英国的NSF（Geophysics）和国家环境研究委员会（NERC）的联合支持下进行（请参阅通讯）。 该奖项中提供了对Sea-Calipso中获得的数据的分析和建模研究阶段的支持。特别是，该奖项为：（1）涉及应变计，CGP，倾斜的钻孔（和辅助表面仪器）的分析：（1）分析，地震和其他数据集，包括校准和建模工作，以推断岩浆系统及其扰动的物理特征（例如，新的岩浆涌入，爆炸）； （2）对海上数据数据的完整分析，建模和解释（由〜100个密封震录记录器记录的3-4个月内的〜100密封地震记录器记录的完整分析和解释，以气枪调查为中心;（3）钻孔天文台分析，层析成像信息以及变形和流体机械师建模的连锁；（4）及时的研究计划计划； （5）教育外展和研究结果的交流。
