Invisible slicks on sea cuts CO2 exchange with air 'by up to 50%'

Description

An invisible layer of scum on the sea surface can reduce carbon dioxide exchange between the atmosphere and the oceans by up to 50%, scientists have discovered.

The world’s oceans absorb around a quarter of all man-made carbon dioxide emissions, making them the largest long-term sink of carbon on Earth.

Greater sea turbulence increases gas exchange between the atmosphere and oceans and until now it was difficult to calculate the effect of “biological surfactants”.
