Abstract : During the contract period the work was performed on the following topics: Description and modeling of the vertical thermohaline and turbulent structure formed by wind induced and convective mixing on shallow sea shelves. Detailed analysis of microstructure and turbulent measurements at the Black Sea shelf in order to study the origin and decay of stratified turbulent patches. Various scaling arguments that are commonly used for stratified turbulent patches as well as certain predictions on marine fossil turbulence were investigated in this work. Evaluation of the effects of boundary mixing in wakes behind small islands on heat flux enhancement in the upper layer of equatorial Pacific. A series of computer programs were developed to process the field experimental data of the first two cases. A numerical model of vertical turbulent mixing was applied to coastal waters affected by active atmospheric forcing.
