 Present study aims to understand the possible influence of changing sea-water pH on the isotopic composition (δ18O and δ13C) of modern planktic foraminiferal shell in twenty three surface sediment samples (including grab and core tops of piston and gravity cores), collected along a north-south trending transect in the western Indian Ocean. The results, though initial indicate that the isotopic values (δ18O and δ13C) in general increase as the sea-water becomes less alkaline. It suggests that the sea-water pH also appears to influence isotopic values of planktic foraminiferal species G. bulloides, besides other factors influencing isotopic values in planktic foraminiferal shell.
