1440506SelkerThis grant provides operational facility support for a collaborative effort between Oregon State University (PI: Selker) and the University of Nevada Reno (PI: Tyler) to allow for continued operations over the next four year of the Center for Transformative Environmental Monitoring Programs (CTEMPs). CTEMPs offers community support for planning, training, equipment loan and field implementation using distributed fiber optic Raman backscatter Distributed Temperature Sensing (DTS) to allow for unprecedented observation of the spatial and temporal distribution of temperature for geoscience and environmental applications including but not limited to, snow, groundwater and watershed hydrology, aquatic and terrestrial ecology, karst geology, soil science (including permafrost studies), physical limnology and oceanography, micrometeorology and glaciology. High resolution DTS systems allow for high spatial (= 0.25 m) and high accuracy (within 0.1 - 0.3 deg C) observations of river bottom, lake, or estuary bottom, snow pack, soil horizon or atmospheric temperatures over length scales from 0.25 ? 2500 m. at high temporal frequency (1 Hz). Temperature precision of +/ 0.01 deg C can be achieved when observation are sampled hourly. When placed in a stream or river, fiber optic DTS allows for observation of the location, temperature, and flux of each groundwater inflow, calculation of an exact heat budget to determine hyporheic exchange, and observation of micro-thermal habitats critical to successful larval fish recruitment. DTS systems were originally developed for applications in the oil and electrical power transmission industries and for fire detection in high rise buildings. Support under this grant will allow for: 1) continued provision of high resolution temperature sensing equipment to the geosciences community using a recently expanded DTS instrument pool; 2) develop and promote the use of actively heated optical fiber sensing for the measurement of soil moisture and fluid flux, and 3) to incorporate the rapidly emerging, but logistically challenging, unmanned aircraft systems (UAS) technology to hydrologic and earth surface monitoring. The CTEMPs facility will offer hands-on training and knowledge dissemination, through its formal designation as a CUAHSI Hydrologic Measurement Facility (HMF) Node and formal agreements with CUAHSI to promote two hands-on workshops per year as well as training on both the OSU and UNR campuses. Outreach to K-8 will also be tested at the T.L. Wells Discovery Museum in Reno through incorporation of DTS in an interactive river display.***

1440506Selkerthisthis Grant为俄勒冈州立大学（PI：SELKER）和内华达大学Reno大学（PI：Tyler）之间的合作努力提供了运营设施的支持，以允许在未来四年的转型环境监测计划（CTEMPS）的未来四年内继续运营）。 CTEMPS使用分布式光纤拉曼反向散射（DTS）为计划，培训，设备贷款和现场实施提供社区支持，以允许对地球科学和环境应用的空间和时间分布进行前所未有的观察，包括但不限于，但不限于，但不限雪，地下水和流域水文学，水生和陆地生态学，喀斯特地质，土壤科学（包括多年冻土研究），物理林科和海洋学，微观历史和冰川学。 高分辨率DTS系统允许高空间（= 0.25 m）和高精度（在0.1-0.3摄氏度内）观察到河底，湖泊，湖泊底部或河口底部，雪包，土壤地平线或大气温度在0.25的长度尺度上？ 2500 m。在高时频（1 Hz）处。 当观察每小时采样时，可以达到 +/ 0.01 ver c的温度精度。 当放置在溪流或河流中时，光纤DTS允许观察每种地下水流入的位置，温度和通量，计算精确的热预算以确定低音交换以及对成功幼虫鱼至关重要的微热栖息地的观察招聘。 DTS系统最初是针对石油和电力传输行业的应用以及高层建筑中的火灾检测开发的。 根据该赠款的支持将允许：1）使用最近扩展的DTS仪器池继续向地球科学社区提供高分辨率温度传感设备； 2）开发和促进使用主动加热的光纤感测度来测量土壤水分和流体通量，以及3）将快速出现的，但具有逻辑上充满挑战的无人驾驶飞机系统（UAS）技术纳入水文和地面监测。 CTEMPS设施将通过其正式名称为CUAHSI水文测量设施（HMF）节点（HMF）节点和与Cuahsi的正式协议，以促进每年两次动手的讲习班以及对OSU和OSU和OSU和OSU的培训，并提供正式的协议，从而提供动手培训和知识传播。 UNR校园。 与K-8的外联还将在T.L.通过将DTS纳入互动式河流展示中，在里诺的威尔斯发现博物馆。***
