Mathematical Modelling and Numerical Simulation of Marine Ecosystems With Applications to Ice Algae

摘要: Sea-ice ecosystem modelling is a novel field of research. In this thesis, the main organism studied sea-ice algae. A basic introduction to algae and its importance in aquatic food web given first. An modeling purposes presented, followed by brief description ice models practice with some physical conditions which influence modelling. following Chapter, simple mathematical model represent population derived, analyzed using pseudo spectral numerical methods implemented MATLAB. The behaviour boundary layers are discussed examining results. Perturbation asymptotic analysis used for further system Maple. Chapter Nutrient Phytoplankton Zooplankton Detritus (or NPZD) model, commonly type marine modelling, developed based on framework Soetaert Herman. examined under five different experimental setups (herein we mean experiments) results discussed. NPZD compared well-studied literature. Our can be considered somewhat simpler than other literature (though it still has much larger parameter space idealized previous Chapter). Finally discuss future directions
