Validating satellite products in order estimate the flux of CO2 between the atmosphere oceans and study ocean acidification
Ocean acidification is caused by the absorption of CO2 released in the atmosphere and it has increased by 26% since the start of the industrial era. The ESA-backed AMT4OceanSatFlux project contributes to the study of ocean acidification by providing measurements of CO2 flux over a range of the Atlantic Ocean.
The AMT4OceanSatFlux project is utilising an eddy covariance technique on board Atlantic Meridional Transect (AMT) cruises to measure gas exchange. These measurements are being used to validate a range of satellite products in order to gain regional and global estimates of the flux of CO2 between the atmosphere and the Atlantic Ocean and evaluate algorithms that are being used to study ocean acidification.
