ABSTRACT: A 100 m deep borehole in mountain permafrost has been equipped with both a thermistor chain and a fiber optic cable for Distributed Temperature Sensing. The device permits to assess the resolution and accuracy of DTS measurements through the comparison of parallel DTS profiles and with classical sensors. First results show that a resolution in the order of 0.1 °C can be achieved, but that the accuracy is strongly dependent on the calibration of the measurement.
