1129003SelkerThis collaborative grant between Oregon State University (PI: Selker) and the University of Nevada Reno (PI: Tyler; EAR-1128999), supports a three year continuation and enhancement of national multi-user facility support for the Center for Transformative Environmental Monitoring Programs (CTEMPs). CTEMPs was established in 2009 with initial support through the American Recovery and Reinvestment Act (ARRA; EAR-0943682). CTEMPs offers community support for planning, training, equipment lease and field implementation using distributed fiber optic methods including Raman backscatter Distributed Temperature Sensing (DTS) to allow for unprecedented observation of the spatial and temporal distribution of temperature for environmental applications including but not limited to, snow, groundwater and watershed hydrology, aquatic and terrestrial ecology, karst geology, soil science (including permafrost studies), atmospheric boundary layer turbulence and glaciology. Data collected using the CTEMPs DTS systems will be integrated into the CUAHSI Hydrologic Information System (HIS) and CTEMPs will become a Hydrologic Measurement Facility (HMF) Node of CUAHSI. CTEMPs plans training workshops and field deployment for up to 26 research projects a year with this support. CTEMPs currently maintains five DTS system, one of which is high resolution, and 27 km of fiber optic cable. High resolution DTS systems allow for near continuous (0.25 m) and precise (+/- 0.3 deg C) observations of river bottom, lake, or estuary bottom, snow pack, soil horizon or atmospheric temperatures over distances as great at 8 km 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 industry and for fire detection in high rise buildings. Support for CTEMPs will make this developing technology available to broader scientific community for marginal instrument lease costs and applications for instrument use will be prioritized by an advisory committee with external representation.***

1129003Selkerththisthisthis俄勒冈州立大学（PI：SELKER）与内华达大学Reno大学（PI：Tyler; EAR-11128999）之间的合作赠款，支持为转型环境监测计划（CTEMPS）的国家多用户设施提供三年的延续和增强。 CTEMPS成立于2009年，并通过《美国恢复和再投资法》（ARRA; EAR-0943682）最初支持。 CTEMPs offers community support for planning, training, equipment lease and field implementation using distributed fiber optic methods including Raman backscatter Distributed Temperature Sensing (DTS) to allow for unprecedented observation of the spatial and temporal distribution of temperature for environmental applications including but not limited to, snow, groundwater and watershed hydrology, aquatic and terrestrial ecology, karst geology, soil science (including permafrost studies), atmospheric边界层的湍流和冰川学。 使用CTEMPS DTS系统收集的数据将集成到CUAHSI水文信息系统（HIS）和CTEMPS中，将成为CUAHSI的水文测量设施（HMF）节点。 CTEMPS计划培训研讨会和现场部署，每年最多26个研究项目。 CTEMP当前维护了五个DTS系统，其中之一是高分辨率和27公里的光纤电缆。 高分辨率DTS系统允许接近连续（0.25 m）和精确（+/- 0.3摄氏度C）观察河底，湖泊或河口底部或河口底部，雪包，土壤地平线，土壤地平线或大气温度，距离为8 km，在高颞频（1 Hz）处于8 km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，计算精确的热量预算以确定低蠕虫交换以及对成功的幼虫鱼招募至关重要的微热栖息地。 DTS系统最初是为石油行业应用和高层建筑中的火灾检测而开发的。 对CTEMP的支持将使该开发的技术可用于更广泛的科学界，以进行边际仪器租赁成本和仪器使用的申请，将由具有外部代表的咨询委员会优先考虑。***
