Eddies aren't the only way the EAC brings nutrients to the surface.

If the atmosphere is considered as a quasi 2D surface, it essentially means that the eddies are bounded by each other.

The motivation for this paper is twofold: first, we validate the model's performance in the Gulf of Mexico by comparing the model fields to past and recent observations, and second, given the good agreement with the observed Gulf of Mexico surface circulation and Loop Current variability, we expand the discussion and analysis of the model circulation to areas that have not been extensively observed / analyzed, such as the vertical structure of the Loop Current and associated eddies, especially the deep circulation below 1500 m.
