Surface salinity profile of Bay of Bengal from November 4 to December 31, 2015, obtained from Argo float data. Note that the maximum decline in salinity (~ 1 psu) occurred on November 30, 2015, just preceding the peak flow accumulation on December 1, 2015, when low-saline waters are likely to have been exported from the coastal region including the residual flow from Pulicat lagoon
