MVP corrected measurements from RESILIENCE

The RESILIENCE experiment took place in April and May 2022 on the R/V Marion Dufresne in the Southwestern Indian Ocean, South of the Mozambique Chanel and offshore of Durban (South Africa). The main scientific objective was to study the interaction at fine scale (about 10km) between physics and biology. To do so CTD stations were performed accompanied by MVP profiles, measuring temperature, conductivity (hence salinity) and fluorescence.

The MVP is performing profiles downward in a free-fall mode and upward, towed by a cable. This instrument is subject to many errors. Here we have first corrected the sensors offset between the CTD and MVP. Second, we have also corrected the thermistor viscous heating and the thermal lag between the thermistor and the conductivity cell. Third, we have corrected the thermal mass error on the lowering profiles. Only temperature and conductivity/salinity measurements are corrected.
