Abstract: The present study is based on two globally significant coastal ecosystems; estuarine and mangrove. The Hooghly estuary is one of the world s major estuaries, fed by one of the world s largest rivers, the Ganges. The Sundarbans mangrove is the world s largest mangrove, which is situated on the Ganges-Brahmaputra delta. Lack of long-term data and the ability to distinguish natural from anthropogenic changes are the major problems in predicting ecosystem responses to human impacts. This study was an attempt to understand the role of mangrove and estuary, in controlling biogeochemical interactions and the transformations of nutrients, chemical contaminants, and radiatively active trace gases, by natural and anthropogenic forcing. The present study depicted that phytoplankton growth and primary production in the Hooghly estuarine, and the Sundarbans mangrove environment was not exclusively dependent on nutrient availability; rather, it To understand the biogeochemical processes, the study of land-ocean interactions was also considered. Three cores (SC1, SC2 and SC3) from the Sundarbans mangrove and one from the Hooghly estuary (HC1) were collected to establish the mass accumulation rate.was majorly dependant upon a proper combination of physico-chemical parameters (transparency, salinity, SPM, temperature, etc.). To understand the sediment geochemistry and the pollution status of the present study milieu, trace metals were estimated in the sediments. The average trend of trace metal concentrations in bed sediments of the Hooghly and the Sundarbans, were in the following sequential order of Fegt Mngt Zngt Crgt Nigt Pbgt Cugt Co. This research was an effort to project the role of tropical estuaries and mangroves in the coastal biogeochemical processes and to understand the importance of anthropogenic effects on coastal ecosystems as a whole on climate change. Such information would aid in evaluating coastal mitigation strategies. newline newline newline
