Real-Time, Long Term Monitoring of Volcanic Emissions

该项目的目标是开发一种能够长期监测火山排放的仪器。这样的仪器可以部署在活跃的火山遗址周围的战略地点，并在长达六个月的时间内无人看管，以监测重要的化学和环境参数。数据将存储在内部计算机中，并通过遥测定期传输到远程观测站。仪器的无人值守部署将大大减少因反复访问偏远地点和火山学家而产生的成本和后勤问题，因为他们拥有关于化学和物理参数的近乎实时的数据，这项技术将是验证与火山活动有关的化学排放模型的宝贵工具。它最终可以作为即将到来的喷发的早期预警系统。虽然这项技术目前还不存在，但由于现代微电子能力和化学传感器技术的最新进展，这样的仪器系统的构建是可能的。这一点在该项目的第一阶段中得到了证明。第二阶段的目标是原型分析仪的设计、制造、优化和现场测试。经过广泛的环境测试后，这些部队将部署在外地。

The goal of this project is to develop an instrument capable of long-term monitoring of volcanic emissions. Such an instrument could be deployed at strategic locations around an active volcanic site and left unattended for periods of up to six months to monitor important chemical and environmental parameters. The data would be stored in an internal computer and periodically transmitted to a remote observation station by telemetry. Unattended deployment of the instrument would greatly reduce the costs and logistical problems associated with repeated visits to remote sites and volcanologists with near-real-time data on chemical and physical parameters, this technology will be a valuable tool for validating models relating chemical emissions to volcanic activity. It could ultimately serve as an early warning system for pending eruptions. While this technology does not currently exist, the construction of such an instrument system is possible because of modern microelectronic capabilities coupled with recent advances in chemical sensor technology. This was demonstrated in Phase I of this project. The objectives of Phase II are the design, fabrication, optimization, and field testing of prototype analyzers. Following extensive environmental testing, the units will be deployed in the field.
