UPSC CAPF – 2018
Salinity in oceans is primarily affected by evaporation, precipitation, freshwater influx from rivers, and freezing/melting of ice. The Arabian Sea experiences a higher rate of evaporation due to clearer skies and higher temperatures in parts influenced by dry winds. Crucially, the Bay of Bengal receives enormous volumes of freshwater from large rivers like the Ganga, Brahmaputra, Mahanadi, Godavari, Krishna, and Cauvery, which significantly dilutes its water and lowers its salinity compared to the Arabian Sea, which receives fewer major rivers.
