It is increasingly clear that near-inertial-wave-driven mixing both below the surface boundary layer and down into the main thermocline is significantly mediated by the presence of mesoscale eddies
In the oceanic zone of northwestern Mexico (including the Gulf of California), paralarval distribution has been associated with the seasonal and interannual advance and retreat of latitudinal distributions of water masses, the northward transport of warm waters by El Nino-Southern Oscillation, the convergence and front formation of surface water masses, retention through mesoscale eddies
, and with adult spawning habitats (Granados-Amores et al.
Zarokanellos uses the gliders to study the mesoscale eddies
of the central Red Sea, focusing on the area of water between KAUST and the Saudi city of Yanbu.
Their topics include early life history, feeding ecology, the formation of a Pacific bluefin tuna fishing ground on their spawning grounds around Ryukyu Islands and implications of a relationship with mesoscale eddies
, otolithic geochemical analysis for stock discrimination and migratory ecology of tuna species, new insights into reproduction in wild and captive species, and a method for measuring the swimming behavior of Pacific bluefin tuna.
The model that the researchers developed for ocean mixing leads to an improved understanding of these mesoscale eddies
and how they mix the waters.
Since mesoscale eddies
markedly affect monthly variations in chlorophyll-a sea surface temperature, and the other characteristics of the upper layer (Piontkovski et al.
Gonzlez-Silveira A, Santamaria del ngel E, Milln-Nuez R, Manzo-Monroy H (2004) Satellite observations of mesoscale eddies
in the Gulf of Tehuantepec and Papagayo (Eastern Tropical Pacific).
The observed trajectories reflect a variety of phenomena, characteristic to the current field of the Gulf of Finland (Figs 4, 5): the presence of relatively small mesoscale eddies
with a diameter of about 5 km to the north of Naissaar, inertial oscillations in the open part of the gulf to the north of Pakri Peninsula and further north of Naissaar, and relatively rapid almost straight alongshore drift apparently steered by topography.
The Northern Gulf of Mexico is frequently impacted by mesoscale eddies
Such models, however, may overlook some of the dynamic features in the Gulf of Finland where resolving the dynamics of mesoscale eddies
(at least in terms of their statistics) requires the use of a horizontal resolution down to 1 NM or even less.

A more unexpected result of the 1972 observations was the discovery of the widespread occurrence of subsurface mesoscale eddies
