Mathematical Modelling and Numerical Simulation of Marine Ecosystems With Applications to Ice Algae
Sea-ice ecosystem modelling is a novel field of research. In this thesis, the main organism studied is sea-ice algae. A basic introduction to algae and its importance in the aquatic food web is given first. An introduction to modeling and its purposes is presented, and this is followed by a brief de...
