Objectif Comprendre et prévoir l'augmentation de production et de l'export en zone frontale : Maîtrise des variables physiques et dynamiques qui entretiennent le front géostrophique : Champ de densité et de courant et leur évolution temporelle à l'échelle de quelques jours, de manière à évaluer proprement la vorticité potentielle et le champ de déformation à l'échelle d'un méandre. Ces observations seront utilisées pour déterminer les circulations secondaires et les variations spatiales à sub-mésoéchelle de la constante verticale de la vitesse. Caractérisation des niveaux primaires et secondaires de l'écosystème/ apport de nutrilites en fonction de la circulation secondaire, changement de composition et d'abondance dans les différentes parties du jet et de ses abords.
