An Analysis on Sound Speed in Seawater using CTD Data

S. Jamshidi and Md N.B. Abu Bakar

Sound speed computation based on field observations of temperature, salinity and pressure in the Southern coastal waters of the Caspian Sea, off Babolsar port in Autumn 2008 was presented. The collected data showed a variation of sound speed between 1488 m sec-1 at the sea surface to 1460 m sec-1 at depth of 42 m in the study area. In the sea surface mixed layer, sound speed mainly ranged between 1487-1488 m sec-1. The results showed strong vertical gradient but weak horizontal gradient of sound speed in the water column. Vertical structure of sound speed indicated a sharply decreasing trend from 1488 to 1460 m sec-1 across the thermocline. The sound speed variations follow the variations in temperature, indicating strong correlation between the two parameters in the study area. Therefore, sound speed was predominantly influence by temperature rather than salinity and pressure.
