Underway temperature and salinity data was collected along the cruise track with two autonomous measurement systems.Usually the active (measuring) and passive (cleaning) systems are swapped every 6 hours. During the cruise the interval was changed to 12 hours. While temperature is taken at the water inlet in about 6.5 m depth, salinity is derived from conductivity and interior temperature within the interior measurement container. Salinity was calibrated independently for both measurement containers (MCs) with direct samples. Temperature was calibrated against CTD data. Except one, all CTD casts were conducted during active periods of MC1. Therefore only the temperature for MC1 was calibrated. For details to all processing steps see Data Processing Report.
