Abstract
Bubble fragmentation drives up to 40% of the CO2 transfer from the atmosphere to the ocean. However, the small size bubble distribution, mainly responsible for gas dissolution, is still poorly understood. Combining experimental and numerical calculations, we find that capillary effects set small bubble production rate which physically explains the origin of their size distribution.
