Short summary

In the ultra-oligotrophic Eastern Mediterranean, winter phytoplankton blooms are enhanced by submesoscale horizontal stirring. Satellite data and simulations show these currents transport chlorophyll-rich coastal waters offshore, contributing ~24.8 % to the seasonal surface chlorophyll increase. This highlights the key role of horizontal processes in bloom dynamics and ecosystem regulation.
