OUTLINE
MOTIVATION: Chemistry and biology in fluid flows. Spatial structure, why it is worth to understand it?
The LINEARLY DECAYING PASSIVE SCALAR
- Spectra
- Chaotic advection: The smooth-filamental transition
- Open vs. closed flows. Multifractality
- Plankton in a meandering jet
PLANKTON PATCHES AND BLOOMS
- Blooms
- Plankton modeling
- Excitability
- Excitability under chaotic advection
