Marine snow morphology illuminates the evolution of phytoplankton blooms and determines their subsequent vertical export
International audience Abstract The organic carbon produced in the ocean’s surface by phytoplankton is either passed through the food web or exported to the ocean interior as marine snow. The rate and efficiency of such vertical export strongly depend on the size, structure and shape of individual p...
