Abstract The effects of climate change on estuarine system is reflected through the changing salinity level of the coastal and estuarine waters, the concentration of dissolved oxygen in water, the levels of pollution and turbidity due to increased rate of erosion etc. In order to get a holistic picture of the climate change we had collected data from two different sectors of Indian Sundarbans (namely western and central sectors) on surface water temperature, salinity and dissolved oxygen for three decades (1980-2009). Our investigation reflects the rising trend of surface water temperatures in both the sectors reflecting the alarming trend of global warming in this part of the Indian sub-continent at the apex of Bay of Bengal. The scenario of salinity profile is conceptualized in two different ways due to variation in geographical features. The ex situ effect of Himalayan deglaciation is confirmed not only by decreasing trend of salinity in the western sector, but also through gradual increase of dissolved oxygen. Keywords: Climate change, Temperature, Salinity, Dissolved Oxygen, Indian Sundarbans. ♯ E-mail: zamansufia123@gmail.com ∏ E-mail: mutpalpaul@gmail.com ☼ E-mail: ricardogobato@seed.pr.gov.br Ξ E-mail: alekssandergobato@hotmail.com ◊ E-mail: abhijit_mitra@hotmail.com
