• Data: 27 stations (July 2009)– Temperature– Salinity– Pressure– U-velocity– V-velocity– Turbidity

• Objective Mapping (Data interpolation)• Calculate Richardson Number

• Calculate Vertical Mixing Coefficient / Vertical Density Diffusivity (Munk & Anderson, 1948)

• Calculate Vertical Mixing Coefficient / Vertical Density Diffusivity (Sangra & Pelegri, 1998)
