This data set contains underway Temperature, Salinity and Fluorescence data collected by a Thermosalinograph (TSG) during the MedSHIP cruise TAlPro2016 (Palermo - Barcelona, RV Angeles Alvariño, 18/08/2016 - 29/08/2016). Underway data was collected along the cruise track with an autonomous TSG system, consisting of a SBE21 together with a SBE38 Thermometer. Both systems worked independent from each other throughout the cruise. While temperature is taken at the water inlet in about 5 m depth (SBE38, S/N 0437, last calibration on 11/07/2008), salinity is estimated within the interior TSG from conductivity and interior temperature (SBE21, S/N 3329, last calibration on 15/01/2016). A Turner fluorometer 10-Au-005 (S/N 7019 RTX, last calibration on 21/01/2016) is connected to the system.

No correction against independent data was performed, neither for temperature nor for salinity.
