This dataset contains raw CTD (conductivity, temperature, depth probe) data for stations conducted during the cruise PS137. Additionally data with the raw, unprocessed position data from a Posidonia acoustic underwater position tracker are supplied as well as scans of the handwritten protocols. The acoustic tracker was mounted at the CTD rosette for most of the stations. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.990389"!
