Underway temperature and salinity data was collected along the cruise track with two autonomous measurement systems. Usually, the systems are changed after 6 hours. While temperature is taken at the water inlet in about 6.5 m depth, salinity is estimated within the interior measurement container from conductivity and interior temperature. Neither temperature nor salinity validation was performed. For details to all processing steps see Data Processing Report. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.993628"!
