Abstract

Two aquatic indicators, namely, Dissolved Inorganic Carbon (DIC) and pH of the aquatic phase were monitored in 18 stations distributed in the western, central, and eastern sectors of Indian Sundarbans during May 2022. A significant spatial variation of these two parameters were observed, which is in accordance with the earlier works. The lowering of pH in all the 18 stations confirms the evidence of acidification in the estuaries of Indian Sundarbans, which may have severe implications on the molluscan community of the estuary that may disrupt the ecological balance evolved in this fragile mangrove ecosystem through the passage of evolution. However, the pace of acidification has found to be of much higher magnitude in the western and central sectors, compared to the eastern Indian Sundarbans. The abundance of halophytes in the eastern sector is the key factor behind the retarding pace of acidification.
