Shutdown of convection triggers increase of surface chlorophyll
The long-standing explanation of the triggering cause of the surface increase of phytoplankton visible in spring satellite images argues that phytoplankton biomass accumulation begins once the mixed layer depths become shallower than a ‘critical depth’. However, a series of recent studies have found...
