1337486 Tyler This collaborative Major Research Instrumentation (MRI) Program grant supports acquisition of three new fiber optic Raman high resolution temperature profilers, or distributed temperature systems (DTS) at the University of Nevada - Reno and Smith College, a non-Ph.D. granting institution.. The instruments will build on capabilities at the Center for Transformative Environmental Monitoring Programs (CTEMPs) and expand capabilities for research and education at Smith College. New higher resolution capable DTS systems now offer the ability to measure temperature with precisions of 0.1 degree C at centimeter scale spatial resolution and temporal resolution of seconds over several kilometers of a fiber optic strand which can be deployed in lakes, rivers, snow pack, trenched in soil, run down boreholes or strung up trees or along civil structures. The capability promises continued advances in understanding of watershed hydrology, limnology, physical oceanography, cryosphere dynamics, soil science and terrestrial ecology. The PIs plan integrated use of multiple DTS systems to enable 2-D and 3-D imaging of environmental temperature fields for specific studies of groundwater recharge of lakes in regions where the Marcellus shale is being hydrofracked for shale gas production and for multi-borehole DTS deployments to image groundwater movements.***

1337486 Tyler这项合作研究仪器（MRI）计划赠款支持在内华达大学 - 里诺和史密斯学院的三个新的光纤拉曼高分辨率温度探索器或分布温度系统（DTS），非PH.D。授予机构。这些工具将以变革性环境监测计划中心（CTEMP）的能力为基础，并扩大史密斯学院的研究和教育能力。现在，新的具有高分辨率的DTS系统具有在厘米尺度上的0.1度C的精确度中测量温度的能力，并在几公里的光纤束上的秒分辨率和时间分辨率的时间分辨率，可以在湖泊，河流，雪堆中部署在土壤中的河流，雪堆中，在土壤中挖掘，撞到钻孔或树木或土木结构堆积。能力有望在理解流域水文学，羊水学，海洋学，冰冻圈动力学，土壤科学和陆地生态学方面的持续进展。 PIS计划在多个DTS系统中的集成使用，以启用环境温度场的2-D和3-D成像，以对Marcellus页岩的湖泊地下水充电进行具体研究，以进行页岩气的生产和多孔孔DTS的部署，以形象地下水。***。***。***。
