The skin of the ocean

On the surface of the oceans is a thin film of water, less than a millimetre thick. According to CNRS researchers, this could influence the amount of CO2 absorbed by the atmosphere.

It's only a thin layer of water, barely a millimetre thick, and yet it could make all the difference. Cooler and saltier, due to water evaporation and surface infrared emission, this film seems to influence the quantities of carbon dioxide captured by the oceans. A scientific study by the CNRS (French National Center for Scientific Research) proves it: the "oceanic skin" allows an additional absorption of between 5% and 15%. A new fact to be taken into account by climatologists the world over.
