Continuous thermosalinograph oceanography along RV METEOR cruise track M156

Underway temperature and salinity data was collected along the cruise track with two autonomous thermosalinograph (TSG) systems, each consisting of a SBE21 TSG together with a SBE38 Thermometer. Both systems worked independent from each other throughout the cruise. While temperature is taken at the water inlet in about 5 m depth, salinity is estimated within the interior TSG from conductivity and interior temperature. Temperature and salinity were calibrated against CTD data from 5 m depth. For details to all processing steps see Data Processing Report.
