Usually, the SMBs are changed after a predefined period, ~12 hours on this cruise. While temperature is taken at the water inlet in about 4 m depth, salinity is estimated within the SMB from conductivity and interior temperature. No temperature and salinity validation was performed. For details to all processing steps see Data Processing Report.-119.4203835-116.800897511.460374325.1775715
