Abstract:
Underway temperature and salinity data was collected along the cruise track with two autonomous measurement systems, called self-cleaning monitoring boxes (SMBs). Usually, the SMBs are changed after 12 hours. While temperature is taken at the water inlet in about 3 m depth, salinity is estimated within the SMB from conductivity and interior temperature. Salinity was calibrated for SMB_A against discrete water samples (see additional attachment). No salinity calibration was performed for SMB_B and no temperature calibration was performed, neither for SMB_A nor SMB_B. For details to all processing steps see Data Processing Report.
