My project consists of studying the air-sea CO2 exchanges in costal environments at different time scales: diurnal to interannual. We rely on high-frequency data from automated buoys of opportunity located in the south western English Channel and French Mediterranean continental shelf. I apply statistical tools to analyse these signals and understand small scale phenomena. For the long term study, I rely on 10 years of data collected by the Roscoff and Villefranche-sur-mer stations (SOMLIT) to assess long-term evolution CO2 air-sea fluxes. The aim of this study is to improve forecast models of CO2 air-sea exchanges by including the high variability of coastal environments.
