Models used in CAMPUS


CAMPUS will be continue developing a number of already established models and applying them to various tasks for the project. 


NEMO is the model of choice for European climate and operational oceanography and is readily configurable for use in shelf seas.  This a hydrodynamic model known as The Nucleus for a European Model of the Ocean, NEMO for short, is managed and developed by an international consortium including the Met Office and National Oceanography Centre.

CAMPUS will work with NEMO at 2 scales:

  • 7km resolution (AMM7), this will be our development platform
  • 1.5km resolution (AMM15), will be the future operational system

These models cover the shelf sea region from northern Spain to Danish belts and north to Iceland.


The Earth and Regional Seas Ecosystem Model (ERSEM) is lower trophic level/biogeochemical cycling model. It describes both pelagic and benthic ecosystems in terms of phytoplankton, bacteria, zooplankton, zoobenthos, and the cycling of C, N, P and Si. ERSEM can be coupled to a 3D hydrodynamic model such as NEMO providing a unique capability to do process studies, simulate the past and future ecosystem states, make operational forecasts, and assess human induced impacts on the ocean.
Appearing in over 100 publications, ERSEM is probably the only model system in the world capable of addressing all of these aspects, due to a number of unique features such as decoupled multiple currencies (C, Chl, N, P, Si and O), a hierarchical foodweb, with plankton functional types and an explicit microbial loop.

Harmful Algal Bloom (HABs) modelling

The modelling of HABs will achieved through the high resolution FVCOM based models. FVCOM is an unstructured grid, coastal ocean model that simulates hydrodynamics from regional to estuarine scales in 3D, and is particularly useful for regions that have irregular and complex coastlines.
