Description: Das Projekt "Untersuchung der Wanderungen von Calanus finmarchius zwischen den Schelfmeeren Nordwesteuropas, ICOS" wird vom Umweltbundesamt gefördert und von Universität Hamburg, Zentrum für Meeres- und Klimaforschung, Institut für Meereskunde (IfM) durchgeführt. ICOS is an interdisciplinary project with the goal to determine the scope for climatically induced spatial and temporal variability in the annual invasion of the Northern North Sea shelf waters by the copepod Calanus finmarchicus. A baroclinic shelf-ocean circulation model, HAMSOM, is applied to generate high resolution three-dimensional hydrodynamic flow-fields. Model results confirm the existence of the energetic North Atlantic Current at the northwest European shelf edge. The branch which flows into the Norwegian trench partly re-circulates to re-join with the North Atlantic Current. However, the main body of the North Sea inflow continues to proceed southward until about 60degree N. The hydrodynamic model is run for the period January to June for several years with realistic time-dependent wind forcing to investigate the observed inter-annual variability of Calanus abundance. Selected episodes from these simulations are run with nested fine-scale model to determine the effect of the higher model resolution on the Lagrangian analysis for the particle tracking model.
