The Gulf of Mannar is a large shallow bay forming part of the Laccadive Sea in the Indian Ocean. The Gulf is noted for religious tourism , trawl net operations and Tuticorin sea port traffic posing a major threat of anthropogenic CO2 emission and ocean acidification. The mean annual rainfall of the region ranged from 762 mm to 1270 mm and pH from 7.0 to 8.3 respectively. pH of Gulf of Mannar waters remain alkaline between 7.7 and 8.5 due to various factors like photosynthesis, respiration, decomposition and freshwater inflow.
