This surface separates the upper ocean, corresponding to the euphotic zone, from the lower, deep ocean. When an eddy transits through, such density surface is deformed. Dependent on the phases of the lifespan of an eddy this will create vertical perturbations in different direction. Eddy lifespans are divided in formation, evolution and ...
Spring blooms are caused by sufficient light reaching the warm, nutrient-rich water contained in the middle of the eddy, due to anticyclonic rotation. A second bloom can occur once the eddy has moved closer to the deep ocean, when the outer reaches of the eddy can gather nutrient-rich water from either the coast or from an adjacent eddy.
The governing forces of an eddy are very dependent on its size. Small eddies are largely governed by viscosity and direction of the flow of a water body. [2] However larger eddies are formed from a balance between the horizontal pressure gradient force, arising from differences in densities of the meeting water masses, and the Coriolis force. [4]
Eddy formations play a vital role in the fate and transport of solutes and particles in environmental flows such as in rivers, lakes, oceans, and the atmosphere. Upwelling in stratified coastal estuaries warrant the formation of dynamic eddies which distribute nutrients out from beneath the boundary layer to form plumes. [ 15 ]

Eddy permitting and eddy resolving models are used to examine the effect of eddy saturation and eddy compensation in the ACC. In these models resolution is of great importance. Ocean observations do not have a high enough resolution to fully estimate the degree of eddy saturation and eddy compensation.

In fluid dynamics, eddy diffusion, eddy dispersion, or turbulent diffusion is a process by which fluid substances mix together due to eddy motion. These eddies can vary widely in size, from subtropical ocean gyres down to the small Kolmogorov microscales , and occur as a result of turbulence (or turbulent flow).
