In a new study, researchers from Bremen map how the Suess effect spreads in the North Atlantic

The use of fossil fuels alters both the concentration and the carbon isotope composition of carbon dioxide in the atmosphere. Since surface water exchanges carbon dioxide with the atmosphere, this also alters the isotopic composition of the carbon dissolved in the ocean. In a study, a team from MARUM – Center for Marine Environmental Sciences at the University of Bremen has now determined how deep this so-called Suess effect has already penetrated into the North Atlantic.
