ABSTRACT
The objective of this study is to investigate the characteristics of the vertical mixing pattern and its temporal and spatial variability. This is accomplished by estimating three mixing parameters: buoyancy frequency, viscous dissipation, and Reynolds stress. The study shows that the dynamical process of vertical mixing is stronger in winter season and weakens with depth. Squared buoyancy frequency has a high of 9.5 X 10-4 s-2 attained at depth 250 m, viscous dissipation rate reaches a maximum of 3 X 10-9 W.kg-1 attained at 15 m, while Reynolds stress has a maximum of 1.1 X 10-4 Pa at 35 m. All these three mixing parameters reach their peak during winter.

Keywords: vertical mixing, stratification, viscous dissipation, buoyancy frequency, Reynolds stress
