Comment:
The water column is divided into two major layers. The surface layer is homogenous with a temperature of between 29 and 30 °C and salinity between 21 and 22. The bottom layer is also homogenous with a temperature of between 17.5 and 18.5 °C and salinity between 24 and 26. The thermocline develops between 5 and 10 m whilst the halocline is sharp and develops between 10 and 20 m. The two layer water structure appears to control the vertical distribution of the DO in the water column in the lagoon. The surface layer is well oxygenated with a concentration ranging from 7 to 8.5 mg/l. Below 7m water depth the DO content continuously decreases reaching a concentration of 2 mg/l at a water depth of 9 m and zero at water depth of about 10 m.
