By absorbing nearly a third of CO2, the oceans play a crucial role in controlling the climate of our planet. However, the accumulation of CO2 in the oceans leads to a decrease in the pH of seawater, a phenomenon known as "ocean acidification".

Objectives

Provide the necessary tools to strengthen the metrological concepts used in oceanography and thus improve the quality of ocean monitoring (pH, conductivity, seawater composition)
