Interannual variability of chlrophyll concentration in the eastern Arabian Sea

Abstract

The monthly mean chlorophyll pigment concentrations and diffuse attenuation were derived for the eastern Arabian Sea [5-16oN; 70-80oE] from SeaWiFS global 9-km resolution data product for the period January 1998 to December 2007. These data were analyzed to understand the seasonal as well as inter-annual variability. The study showed a clear seasonal variability with highest chlorophyll concentration during July-August and least in April. The inter-annual variability showed an increasing trend from 1998 to 2007.
