The model ECOHAM1 is a computer model which can be used to calculate annual and long-term phytoplankton dynamics for shelf seas in a three-dimensional physical environment. It is one of four community models of the German Climate Research modelling group called Bio-Geo-Chemistry and Eco-System models. Applications of ECOHAM1 exist for the North Sea (Moll, 1998) and the Bohai Sea (Wei et al., 2003). An extensive overview on biogeochemical/ecological modelling in the North Sea was provided by Moll and Radach (2001) and Moll and Radach (2003).
