The Arabian Sea surface chlorophyll data derived from the Sea Wifs sensor during the post ENSO (1997-98) months analyzed with reference to its corresponding monthly climatic data. The monthly color response computed through differentiation and normalization with reference to its climatic value and represented in percentages. The trends observed in inter and intra-annual mode for the months of 1998 to 2000 analyzed in relation to similar observation made with sea surface temperature (SST) over the area. Analysis also carried out in relation with the changes in weather and climate over the area and the prevailing oceanic processes. The color response indicated about 30% change in surface chlorophyll over the period. The lower concetraiton of sruface chlorophyll observed in 1998 increased from 40% in 1999 to 60% in 2000, respectively. The annual change observed in ocean color response was about 23.7% in 1999 and 3.4% in 200 over their previous years. The average annual change in surface chlorophyll over the period 1998-2000 was about 11.32%, while peak rates of monthly change recorded to an extent of -38.6% in April 1998 to a maximum value in 40.07% in February 1999. Similar responses also observed in the SST of the area. The thermal response observed in the Arabian Sea was compared with those in the central and the eastern Pacific Ocean. These changes were attributed to the changes in ocean and atmospheric processes during summer and winter months, including that of 1997-98 ENSO phenomena.
