Interplay of Fluid Dynamics and Biology of Plankton Population Models

Plankton constitutes the largest component of the world's biomass, exerting a vital influence on global fluxes of CO2 and other important climatological gases, such as dimethyol sulphate, as well as forming the basis of marine food webs. Mathematical models describing the complex and highly nonlinear population dynamics of plantlike phytoplankton and herbivorous (and sometimes carnivorous) zooplankton vary from many-component systems of PDEs, designed for accurate simulation, to much simpler 3 or even 2 component models, designed to explore crucial processes in the simplest context.The interplay of this light sensitive biology with fluid flow has been little explored as yet and the minisymposium will bring together some of the existing approaches.
