Underway temperature and salinity data was collected along the cruise track with the thermosalinograph (TSG) , which is part of the Surface Monitoring Box (SMB). The TSG worked successfully throughout the cruise. While temperature is taken at the water inlet in about 3.5 m depth, salinity is estimated within the interior TSG from conductivity and interior temperature. No processing, correction or calibration against independent data was performed.

Water was pumped and analysed only from backboard side of ship.
