| Narrative summary of dataset | Repeat hydrography, as organized through the GO-SHIP network, is fundamental for detecting trends and variability also in the Mediterranean Sea. The Mediterranean component of GO-SHIP is MedSHIP, and TAlPro is the western Mediterranean component. The TAlPro2022 cruise consisted of 26 full depth hydrographic stations crossing the Tyrrhenian Sea from north to south, then the Algero-Provencal Basin from south to north. Here the postcalibrated bottle file data are made availiable. Postcalibration has been done by measuring dissolved oxygen and salinity on water samples collected by the rosette. |
| Summary of processing methodology | The header of the cnv files created by the SBE PostProcessing Software is pasted below to show the steps of postprocessing. In addition the salinity and dissolved oxygen data have been postcalibrated by using the water samples analysis (salinometer and Winkler titration). The new coefficients that have been applied were: for salinity SLOPE=1.00018712757570; for dissolved oxygen SOC = 0.51092, Voffset = -0.49277, E = 0.0371.
