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. ***

0930045Chadwick 这笔赠款支持升级加拉帕戈斯群岛内格拉火山的连续 GPS (CGPS) 网络。 最初的网络是通过之前的 NSF/EAR 支持来资助的。 升级将包括采购和现场部署四个新的双频 GPS 接收器和无线电调制解调器。 此次升级将用双频接收器完全取代 Sierra Negra 网络中剩余的单频接收器，并大大增强了板载内存。 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。 这个火山系统的动力学提供了一个绝佳的机会来更多地了解岩浆侵入和地表变形之间的相互作用。 Sierra Negra 网络收集的所有 GPS 数据将继续通过 UNAVCO 数据系统近乎实时地免费访问。 ***
