Also since the late 1970s some measurements of higher accuracy have been made of several properties of seawater such as (i) heat capacity, (ii) sound speed and (iii) the temperature of maximum density. Here a is the speed of sound in the medium, and v is the speed of the object. Mach number is used to represent speeds for objects moving close to the speed of sound or faster, such as aircraft. It is not a constant it depends on the medium, which in turn varies with pressure and temperature. An exact expression for the isothermal sound speed in a seawater is obtained from an internationally accepted equation of state. This derived sound-speed expression offers certain practical and theoretical advantages over empirical formulations encountered elsewhere in the literature. 2002, USAGE 2002) a-) from empirical formulas with the information from CTD (Conductivity, Temperature, and Depth) sensor -or probePike, J.
