The station 91 isn’t at the same exactly GPS point than Ovide section. The core of the work consisted in acquiring surface-to-bottom hydrographic profiles of pressure, temperature, salinity and dissolved oxygen, and analyzing 17 physical and biogeochemical tracers from 11500 samples drawn from the Niskin bottles of the CTD frame. We report here a focus on the acquisition and calibration steps of the physical ...
