Dinámica no-lineal y transporte en el Golfo de México

Conferencia de Maria Josefina Olascoaga

In this talk I will present results from a series of recent efforts aimed at advancing knowledge of the Lagrangian circulation in the Gulf of Mexico (GoM).  In these efforts we have specifically sought to unveil the building blocks that form the skeleton of the Lagrangian circulation.  These are given by especial surfaces composed of fluid trajectories, widely known Lagrangian Coherent Structures (LCS), which exert the largest influence on nearby fluid, thereby shaping global transport and mixing.  Results include the discovery of recurrent LCS in the GoM which act as conduits for the transport material as well as semipermanent LCS that provide a great deal of isolation for the continental shelves.  Implications of the presence of these structures for pollutant and larval dispersal as well as algal bloom development are discussed.
