TL;DR: In this article, a mixed-layer model is used to investigate the formation of Levantine Intermediate Water (LIW) over the Eastern Mediterranean, and the preferred formation region for LIW is found through idealized experiments to be controlled by the preconditioning of the hydrography, especially that of the cold, cyclonic Rhodes gyre, rather than by the pattern of the climatological fluxes.

TL;DR: In this paper, the authors used a revised version of the Comprehensive Ocean-Atmosphere Data Set (UWM/COADS) to test air-sea fluxes from a revised versions of the comprehensive ocean-atmosphere data set and found that the discrepancy was attributed to systematic errors in the bulk formulas used to calculate the heat flux components.

TL;DR: In this paper, it was shown that there is no simple relationship between the advective and diffusive fluxes, and that the flow through the base of the mixed layer can be derived from the derivative of the surface buoyancy flux with respect to buoyancy.

Abstract: The circulation of the Red Sea is driven by strong surface evaporation, but the buoyancy budget alone cannot determine the circulation and thermohaline structure. The circulation could be rapid with weak stratification or slow with strong stratification. These possible states are examined in the dynamical framework of Phillips' similarity model applied to the upper 140 m. A large eddy viscosity in the return flow between 70 and 140 m is required for the solution to match the observed stratification. The circulation for this solution is slow, in accord with the weak geostrophic currents observed in the Red Sea, and partially justifies the neglect of rotation. The internal viscous force required to match the model to observations seems too big to be a proxy for bottom friction on the sloping sides, though the mismatch is not large at the southern end of the Red Sea if the model is modified to allow for decreasing width with depth. The model may also be used to confirm that forcing by the wind stress is of secondary importance. Overall, the Red Sea appears not to be overmixed, though the model displays the counterintuitive result that increased vertical mixing increases the buoyancy difference between surface and bottom.

TL;DR: In this article, a 2.5-month realistic simulation was performed to investigate the processes of dense water formation and cascading in the Gulf of Thermaikos (North Aegean).
