The motivation to study the vertical exchanges of tracers associated with mesoscale eddies
is that the mean concentration of most oceanic tracers changes rapidly with depth. Because …

This work reviews the present position of and surveys future perspectives in the physics of
chaotic advection: the field that emerged three decades ago at the intersection of fluid …

Explanations for the patchy distribution of marine phytoplankton are critically reviewed with
the focus on the role played by lateral advection and mixing. Generating mechanisms for …

The effect of the geostrophic stirring on phytoplankton variability during the northeast Atlantic
spring bloom is studied by analyzing satellite derived surface chlorophyll, sea surface …

Chemical and biological processes often take place in fluid flows. Many of them, like
environmental or microfluidical ones, generate filamentary patterns which have a fractal …

Transport and mixing properties of surface currents can be detected from altimetric data by
both Eulerian and Lagrangian diagnostics. In contrast with Eulerian diagnostics, Lagrangian …

The horizontal stirring properties of the flow in a region of the East Australian Current are
calculated. A surface velocity field derived from remotely sensed data, using the maximum …

In order to understand the dynamics in more detail, in particular for visualizing the space-
filling unstable foliation of closed chaotic Hamiltonian systems, we propose to leak them up …

In the subtropical gyres, phytoplankton rely on eddies for transporting nutrients from depth to
the euphotic zone. But, what controls the rate of nutrient supply for new production? We …

We review and generalize recent results on advection of particles in open time-periodic
hydrodynamical flows. First, the problem of passive advection is considered, and its fractal …
