Contains data for SNMR and CSAMT surveys published in: Keating, Binley, Bense, Van Dam, & Christiansen (2018) Combined geophysical measurements provide evidence for unfrozen water in permafrost in the Adventdalen valley in Svalbard, Geophysical Research Letters. SNMR folder contains data for the 14 SNMR location analyzed in Keating et al. (2018) and contains five subfolders Data - (folder) contains the filtered SNMR data as a text file, this is the same data contained in the filtered file in a more accessible format Filtered - (folder) contains the filtered SNMR data as a MATLAB *.mat file as output from the QC Vista Clara Program, this data can be used directly in MRSMatlab to invert the SNMR data and obtain a water content with depth profile Information - (folder) contains the information about the SNMR survey (location, pulse moments, loop size, larmor frequency, etc) necessary to invert the data as a text file. Inverted - (folder) contains the inverted SNMR profiles used in Keating et al. (2018) as a text file. Larmorfrequency - (folder) contains the magnetic field variation, converted to the Larmor frequency, throughout each survey duration as a text file. CSAMT folder contains data for the 10 CSAMT locations analyzed in Keating et al (2018) and contains 2 subfolders and 3 files Inverted - (folder) contains the inverted CSAMT profiles used in Keating et al. (2018) as a text files Raw - (folder) contains the raw CSAMT data in Geometrics Stratagem format (see ftp://geom.geometrics.com/pub/GeoElectric/Manuals/EH4_manual_F.pdf), each dataset is contained in a subfolder CSAMT_Information - (excel file) contains all the information about each survey, including location and Tx/Rx distance. MT_UV - (file) contains the up-valley CSAMT profile data in IPI2IN(MT) format (see http://geophys.geol.msu.ru/ipi_mts/wmts_en.pdf) MT_XV - (file) contains the cross-valley CSAMT profile data in IPI2IN(MT) format (see http://geophys.geol.msu.ru/ipi_mts/wmts_en.pdf)
