description |
International audience Following the anomalous warming event occurring in the tropical North Atlantic in 2010, higher than usual surface fugacity of CO 2 ( f CO 2 ) was observed. To evaluate the spatial extent of these anomalies and their drivers, and to quantify the sea-air CO 2 flux at basin scale, the Mercator-Ocean model is used from 2006 to 2014 within the region 0-30°N, 70-15°W. Model outputs are generally in accordance with underway sea surface temperature, sea surface salinity, and surface f CO 2 recorded by two merchant ships. The anomalous warming of 2010 is well reproduced by the model and is the main driver of f CO 2 anomalies. The first coupled Empirical Orthogonal Function mode, between sea surface temperature and f CO 2 , captures more than 70% of the total variance and is characterized by a basin-scale warming associated to positive f CO 2 anomalies. The corresponding principal components are correlated to the Tropical North Atlantic Index and identify 2010 as the year with the highest positive anomaly over 2006-2014. Exceptions to this general pattern are located near the African coast, where the weakening of the coastal upwelling causes negative inorganic carbon anomalies, and close to the Amazon River plume, where f CO 2 anomalies are primarily associated with sea surface salinity anomalies. Although the f CO 2 anomalies of 2010 appear mostly in spring, they affect the annual CO 2 budget and lead to an increased CO 2 outgassing twice as large (46.2 Tg C per year) as the mean annual flux over the 2006-2014 period (23.3 Tg C per year). |
