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. Salinity was calibrated independently for both measurement containers (MCs) with coefficients obtained during the two following cruises MSM88/2 and MSM89. No temperature calibration was performed. For details to all processing steps see Data Processing Report.

Salinity Offset MC1 = 0.017853 Salinity Offset MC2 = -0.061511
