dc.description.abstractSound speed computed from annual mean temperature and salinity data of Levitus reveals that spatial variation in the Arabian Sea is greater than that in the Bay of Bengal. Maximum spatial variation of sound speed in the Arabian Sea noticed between the depth levels 200 to 1500 m is due to the combined effect of variation in the salinity (to a larger extent) and temperature. In the Bay of Bengal though the spatial variation of sound speed is marginal, variations observed between 1500 m are brought about by warm Andaman Sea waters. The depth limited nature of annual mean sound speed profile for 2 marginal seas suggests that the effective acoustic channel lies much below (approximately 300 m) the surface. This results in acoustic propagation in the form of surface-refracted bottom-reflected (RBR) rays within the SOFAR channel
