Biopolymers form a gelatinous microlayer at the air-sea interface when Arctic sea ice melts
The interface layer between ocean and atmosphere is only a couple of micrometers thick but plays a critical role in climate relevant processes, including the air-sea exchange of gas and heat and the emission of primary organic aerosols (POA). Recent findings suggest that low-level cloud formation ab...
