Motivations
Different components : (phyto, zoo, nutriments, viruses,...).
Many interactions/coupling: (atmosphere/ocean, predator-prey, consommation,...).
Hydrodynamic transport: (turbulence: large range of scales, mixing, lost of predictability, stochastic aspect,...)
→ complex systems, "nonlinear"
, large number of degrees of freedom → need specific methods for the analysis
