Field Workshop on the Chemistry and Flux of Volcanic Volatiles: Nicaragua and Costa Rica

该奖项将支持一个现场研讨会，以测量和采样中美洲火山弧的尼加拉瓜和哥斯达黎加段火山中心的挥发性排放物。这次研讨会是IAVCEI火山气体化学委员会（CCVG）组织的第八次现场研讨会，将于2003年3月举行。讲习班的总主题是利用直接取样方法和新开发的陆基和天基遥感技术对火山挥发性排放物进行取样。组织者和与会者将比较技术，并确定方法，以改善目前的测量策略。讲习班的重点是哥斯达黎加的波阿斯火山和尼加拉瓜的马萨亚、莫莫通博和塞罗内格罗火山。由于俯冲带参数显示哥斯达黎加和尼加拉瓜之间的显着变化（沉积物的量弧岩浆，板角）从这些火山中心的挥发性排放物的比较预计是有趣的。通过让大量专家参与进来，我们希望最准确地解决不同火山之间挥发性成分和流量的变化，并消除与采样和测量技术有关的问题。

This award will support a Field Workshop to measure and sample volatile emissions from volcanic centers in the Nicaragua and Costa Rica segments of the Central American Volcanic Arc. This workshop is the 8 th Field Workshop organized by the IAVCEI Commission on the Chemistry of Volcanic Gases (CCVG) and will take place in March 2003. The overall theme of the workshop is sampling of volcanic volatile emissions using direct sampling methods and newly developed land-based and space-based remote sensing techniques. Organizers and attendents will compare techniques and identify methods to improve current measurement strategies. The focus of this workshop is Poas volcano in Costa Rica, and Masaya, Momotombo and Cerro Negro volcanoes in Nicaragua. Because subduction zone parameters show significant changes between Costa Rica and Nicaragua (amount of sediment contributing to arc magmas, slab angle) comparison of the volatile emissions from these volcanic centers is expected to be interesting. By involving a large number of specialists we hope to most accurately resolve variations in volatile compositions and fluxes between the different volcanoes and eliminate problems related to sampling and measuring techniques.
