“You’ve never noticed this layer for the simple reason that it’s less than a tenth of a millimeter thick, about the same thickness as a single strand of human hair, protecting the ocean the way, well, skin does. This “skin” develops at the surface of the ocean (as well as on lakes and ponds) where organic compounds come into contact with the atmosphere. It affects how quickly gasses can exchange between the atmosphere and the ocean. Since calculating the speed at which carbon dioxide exchanges is a critical component of atmospheric models, the resulting data here should help scientists model the future climate with increased accuracy.” – via Inverse
