Data corresponds to the long-term monitoring of streambed sediments conducted in Kerbernez through Fiber Optic (FO) DTS technology. The streambed temperature is continuously monitored at high resolution all along the FO cable in order to highlight and quantify groundwater/stream exchanges. Further details are available in the file: http://agrhys.fr/BVE/nataline/mesurespassives/infos.pdf and results are presented in Simon et al. (2021)

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)
