We study the interplay of hydrodynamic transport and plankton dynamics
in the Benguela upwelling system. We use a coupled system of oceanic
flow and a simple biogeochemical model (NPZ type). For the oceanic
flow we use two different velocity fields: a) one derived from
altimetry data from satellite to study the surface dynamics, and b)
from a 3D numerical model, which allows to study the vertical
component. The calculation of unstable manifolds is used as a
diagnostic of the transport properties of the velocity field. We study
the effect of the horizontal transport and of the vertical component
in the formation and dynamics of plankton structures.
