Phytoplankton blooms dynamically enrich dissolved organic carbon (DOC) in sea spray aerosol by 10–30 times, with proteins and saccharides transferring at different bloom stages. The sea-to-air transfer of DOC is driven by the synergy of biological and the interaction between DOC and bubble rupture. This synergistically-driven DOC flux affects aerosol properties and climate, highlighting the ocean–atmosphere link in organic carbon cycling.
