Abstract

A nonlinear integro-differential equation is used to investigate the effects of ocean iron fertilization on the evolution of the phytoplankton biomass. This equation contains terms responsible for fragmentation, coalescence, growth-decay, grazing, and sinking of the phytoplankton aggregates. The evolution equation is analyzed by using the theory of semilinear dynamical systems and numerical simulations are performed. Our results demonstrate the validity of the iron hypothesis in fighting climate change.
