The AMT4OceanSatFlux project is utilising an eddy covariance technique on board the 28th Atlantic Meridional Transect (AMT) cruise to measure gas exchange. These measurements will be 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.

This programme builds upon the work of the AMT4SentinelFRM programme which made fiducial reference measurements at sea to calibrate and ensure the quality of data from the Sentinel satellites. This enables us to use the data from the satellites with greater confidence. With it we can address large scale issues and scientific questions on the effects of climate change in the global ocean, focusing on those that have a direct bearing on societal issues that humankind will face in the coming decades.
