In the present study, were explored enhancement of chlorophyll-a (Chl-a) concentration after the passage of cyclone in the Bay of Bengal. Multi-satellite observations and vertical profiles from Argo floats were used. Low Chl-a concentration, high sea surface temperature (SST) and sea surface height (SSH) was identified before the passage of the cyclone at coastal Andhra Pradesh. After the passage of cyclone there is drastic change in chl-a (7 mg/m3) was observed along with low SST and SSH. This uptake of nutrient flux by cyclone induced upwelling along the Andhra coast has the potential to support new production.
