Objective	Study of the summer monsoon regime in the Red Sea and the nearby Gulf of Aden. To estimate the carbon budget in the Bab-El-Mandeb Strait and the flux of carbonate particles sedimenting in the basin. Study the variation of the global "carbon dioxide / bicarbonates + dissolved carbonates / solid carbonates" system on a longitudinal section in the Red Sea.
