0930045ChadwickThis grant supports upgrade of a continuous-GPS (CGPS) network on Sierra Negra volcano in the Galapagos. The original network was funded through previous NSF/EAR support. The upgrade will include acquisition and field deployment of four new dual frequency GPS receivers and radio modems. The upgrade will completely replace remaining single frequency receivers in the Sierra Negra network with dual frequency receivers with greatly enhanced on board memory. The upgraded CGPS network will allow for continued observations of one of the most active basaltic volcanoes in the world. The dynamics of this volcanic system allows for an extraordinary opportunity to learn more about the interplay between magma intrusion and surface deformation. All of the GPS data collected by the Sierra Negra network will continue to be freely accessible through the UNAVCO data system in near real time. ***

这笔拨款用于升级加拉帕戈斯群岛Sierra Negra火山上的连续gps （CGPS）网络。最初的网络是由以前的NSF/EAR支持资助的。升级将包括获取和现场部署四个新的双频GPS接收器和无线电调制解调器。此次升级将完全取代Sierra Negra网络中剩余的单频接收器，取而代之的是双频接收器，其机载内存大大增强。升级后的CGPS网络将允许对世界上最活跃的玄武岩火山之一进行持续观测。火山系统的动力学为了解岩浆侵入和地表变形之间的相互作用提供了难得的机会。内格拉山网络收集的所有全球定位系统数据将继续通过联安援助团数据系统几乎实时地免费提供。＊＊＊
