Dissolved Inorganic Carbon and Total Alkalinity have been sampled at 5m and 10m depth at Boussole site (43°22' N, 7°54' E ) in the western Mediterranean Sea, approximately every 2 months from 2014 to 2019.

These data have been used by Merlivat et al. (2018). They are part of the Biocarex project.

Samples have been analyzed at the SNAPO-CO2 (Service National d’Analyse des Paramètres Océaniques du CO2) located at the Laboratory LOCEAN in Paris (https://www.locean-ipsl.upmc.fr/SNAPO/).

Flags for doubtful analysis and doubtful bottles are indicated.
