Kerbernez : Active-Distributed Temperature Sensing (DTS) measurements – April 6th,2016
Data corresponding to the active-DTS experiment conducted in Kerrien by deploying and burying an heatable FO cable in the streambed sediments (in the wetland area). Further details are available in the file: http://agrhys.fr/BVE/nataline/mesuresactives/infos.pdf and results are presented in Simon et al. (2021)
A 150 m length of BruSens FO cable has been connected to a FO-DTS control unit, a Silixa Ultima S instrument. The unit was configured in double-ended configuration to collect data at 12.5 sampling cm and 60 seconds time interval. The effective spatial resolution of DTS measurements with this unit was estimated varying between 66 and 90 cm. Two sections of 20 m of FO cable were installed inside calibration baths (a cold calibration bath and a warm one) and RBR SoloT probes (0.002°C accuracy) were used to calibrate the data.
Purpose: Active-DTS measurements conducted in streams are infrequent. Any could use these data to test data interpretation methods for instance.
