TL;DR: A pelagic marine ecosystem simulation model ERSEM-2004, developed from the European Regional Seas Ecosystem Model (ERSEM II), is presented along with a parameter set applicable to six highly contrasting sites, ranging from a temperate mixed shelf station to a permanently stratified tropical deep-ocean station.

TL;DR: A series of techniques are described, including a 2-stage self-organising map (SOM), non-parametric multivariate analysis, and error statistics, to a complex spatio-temporal model run for the period 1988–1989 in the Southern North Sea, coinciding with the North Sea Project which collected a wealth of observational data.

TL;DR: A detailed mathematical description of all ERSEM components is provided along with case studies of mesocosm-type simulations, water column implementations, and a brief example of a full-scale application for the north-western European shelf.

TL;DR: In this article, an approach to complex spatio-temporal marine ecosystem modelling as applied to the North Western European Continental Shelf is presented. But the model presented here goes further than previous work, as they combine a higher resolution hydrodynamic model, the POL-3DB baroclinic model with the European Regional Seas Ecosystem Model.

TL;DR: In this paper, a series of coupled hydrodynamic ecosystem modelling simulations, using the POLCOMS-ERSEM system, were presented, showing that changes in oceanic nutrients are a first order factor in determining changes in the primary production of the northwest European continental shelf on time scales of 5-10 yr.
