| Objective | The main objective of the CARBOHONE 1 cruise was to study air-sea CO2 exchanges in the Gulf of Lion and the Rhone delta. Biogeochemical characteristics of surface waters are influenced by river inflows from the Rhone. Therefore, there were several main technical objectives: 1/ acquiring the most data possible on surface temperature and salinity by using RV L'Europe's TSG to map the Rhone River's plume; 2/ acquire the most surface data possible for pCO2 and dissolved O2 to calculate the air-sea exchanges in the estuary and on the shelf; 3/- covering a network of 25 stations on the shelf with CTD profiles and sampling a series of biogeochemical parameters in order to determine which processes control these exchanges of CO2 between the air and sea. These studies will make it possible to determine how the estuarine plume influences air-sea fluxes of CO2 over the entire shelf, which factors control inter-seasonal variations of these CO2 fluxes and how variable the CO2 air-sea fluxes are in the range of estuarine plumes encountered on the global scale of the ocean. |
