Why study mesoscale mixing of plankton?
Because it happens:
- plankton and mesoscale flows are ubiquitous
  in the oceans
Yet we have little understanding of their interactions
Patchiness problem:
- countless observations reveal heterogeneity in
  plankton distributions at all scales
The causes are still hotly debated – physics or biology?
Production:
- large scale simulations show production increases
    with resolution
- process studies show that mixing is a strong control
  of production at the mesoscale and sub-mesoscale
GCCMs fail to resolve these scales – at what cost?
