MRI Collaborative: Acquisition of Expanded Distributed Temperature Sensing Instrumentation to Serve Community Demand and Stimulate Undergraduate Discovery

该合作主要研究仪器（MRI）计划资助内华达大学里诺分校和史密斯学院购买三台新的光纤拉曼高分辨率温度分析器或分布式温度系统（DTS），非博士。授予机构. .这些仪器将建立在变革环境监测项目中心（CTEMPs）的能力基础上，并扩大史密斯学院的研究和教育能力。新的高分辨率DTS系统现在能够在厘米尺度空间分辨率下以0.1摄氏度的精度测量温度，在几公里长的光纤链上以秒的时间分辨率测量温度，这些光纤链可以部署在湖泊，河流，雪堆，土壤沟渠中，沿着钻孔或挂在树上或沿着土木结构。这种能力保证了对流域水文学、湖沼学、物理海洋学、冰冻圈动力学、土壤科学和陆地生态学的不断了解。pi计划综合使用多个DTS系统，实现环境温度场的二维和三维成像，用于对Marcellus页岩进行水力压裂以开采页岩气的地区的湖泊地下水补给进行具体研究，并用于多井DTS部署以成像地下水运动

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.***
