Rao, XH, Smitha, A, Ali, MM (2006). A study on cyclone induced productivity in south-western Bay of Bengal during November-December 2000 using MODIS (SST and chlorophyll-a) and altimeter sea surface height observations. INDIAN JOURNAL OF MARINE SCIENCES, 35(2), 153-160.

Abstract
MODIS (Moderate Resolution Imaging Spectroradiometer) on board TERRA weekly composite mean products of sea surface temperature (SST) and chlorophyll-a, and modeled ocean net primary productivity with a spatial resolution of 4.63 km and altimeter derived sea surface height (SSH) data are used to study the changes in the primary productivity (PP) induced by the November-December 2000 tropical cyclone in the Bay of Bengal. A maximum SST drop of 2 degrees C, a sea surface depression of 10 em compared to the periphery, increase in chlorophyll-a by 1.5 mg/m(3) and enhanced average mixed PP of 964 gC/m(2)/y were observed around 11.0 degrees N and 81.0 degrees E after the passage of the cyclonic storm. The enhanced PP after the passage of the cyclone supports the base of the pelagic marine food web, directly affecting the fishery productivity.
