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. Temperature and salinity were calibrated against CTD data from 7 m depth. For details to all processing steps see Data Processing Report.
Temperature was calibrated independently for both MCs against CTD data from 7 m depth. Value added to temperature data MC1 = -0.09410. Value added to temperature data MC2 = -0.03363.Salinity was calibrated independently for both MCs against CTD data from 7 m depth. Value added to salinity data MC1 = 0.00725. Value added to salinity data MC2 = -0.00399.
