  • Calibrating Single-Ended Fiber-Optic Raman Spectra Distributed Temperature Sensing Data 
    Hausner, Mark B.; Suarez, Francisco; Glander, Kenneth E.; van de Giesen, Nick; Selker, John S.; Tyler, Scott W. (Multidisciplinary Digital Publishing Institute, 2011-11)
    Hydrologic research is a very demanding application of fiber-optic distributed temperature sensing (DTS) in terms of precision, accuracy and calibration. The physics behind the most frequently used DTS instruments are co ...
  • Distributed fiber-optic temperature sensing for hydrologic systems 
    Selker, John S.; Thevenaz, Luc; Huwald, Hendrik; Mallet, Alfred; Luxemburg, Wim; van de Giesen, Nick; Stejskal, Martin; Zeman, Josef; Westhoff, Martijn; Parlange, Marc B. (American Geophysical Union, 2006-12-06)
    Instruments for distributed fiber-optic measurement of temperature are now available with temperature resolution of 0.01°C and spatial resolution of 1 m with temporal resolution of fractions of a minute along standard fi ...
  • Double-Ended Calibration of Fiber-Optic Raman Spectra Distributed Temperature Sensing Data 
    van de Giesen, Nick; Steele-Dunne, Susan C.; Jansen, Jop; Hoes, Olivier; Hausner, Mark B.; Tyler, Scott; Selker, John (MDPI Publishing, 2012-05)
    Over the past five years, Distributed Temperature Sensing (DTS) along fiber optic cables using Raman backscattering has become an important tool in the environmental sciences. Many environmental applications of DTS dem ...
  • Feasibility of soil moisture monitoring with heated fiber optics 
    Sayde, Chadi; Gregory, Christopher; Gil‐Rodriguez, Maria; Tufillaro, Nick; Tyler, Scott; van de Giesen, Nick; English, Marshal; Cuenca, Richard; Selker, John S. (American Geophysical Union, 2010-06-05)
    Accurate methods are needed to measure changing soil water content from meter to kilometer scales. Laboratory results demonstrate the feasibility of the heat pulse method implemented with fiber optic temperature sensing ...
  • Fiber optics opens window on stream dynamics 
    Selker, John; van de Giesen, Nick; Westhoff, Martijn; Luxemburg, Wim; Parlange, Marc B. (American Geophysical Union, 2006-12-19)
    A new approach to monitoring surface waters using distributed fiber optic temperature sensing is presented, allowing resolutions of temperature of 0.01°C every meter along a fiber optic cable of up to 10,000 m in length. ...
