RESPONSE OF CHLOROPHYLL-a TO SEA-LAND BREEZE IN A SEMIENCLOSED SEA

Abstract

To investigate remediation and enhancement of polluted marine environment, an environmental monitoring have been carried out at a special floating laboratory in Kaita Bay. This monitoring includes meteorological observation, current profiling and water quality measurement. The results indicated that sea-land breeze, which is common phenomenon around the coast of the Seto Inland Sea, greatly affects the marine environment of Kaita bay. Especially, time variation of chlorophyll-a at 4m depth had apparent diurnal oscillation that had good correlation with the movement of thermal stratification, which might be driven by sea-land breeze. The correlation between this oscillation and existence of sealand breeze had a statistical significance.
