Characterization of sound speed profile in Malaysian Sea off Tanjung Balau

摘要

Underwater communications exists in many applications, providing information about the ocean floor such as bathymetry, for environmental pollution monitoring, information exchange between divers and sea vessel, and collection of scientific data. However, the propagation of sound in the sea is dependent on several environmental factors such as pressure which is related to depth, and some other ocean properties. The characteristic of sound propagation in the sea is determined by what is known as the sound speed profile. The speed of sound in the sea is determined and varies with depth, salinity change, temperature, the season as well as the geographic location. In general, different sea conditions has different characteristics of the sound speed profile. This project was aimed to determine the sound speed profile in Malaysian Seas. Parameters, which affect the sound speed profile, were studied, and their values determined.
