Sea ice buoy saltharp was deployed at the MOSAiC LM-site from mid January to August 2022. It measured autonomously and non-destructively the temperature and conductivity between horizontal wire pairs, from which we retrieve solid fraction and sea ice bulk salinity profiles. This dataset contains the raw data of saltharp as it was received onshore via satellite link. The saltharp had severe technical problems, making most of the data unusable. A processed data set will exclude these values. Definitely wrong ones have already been replaced here with -999. as NaN indicator. Further information on the data format and the measurement record are collected in the attached protocol documents.
