Sound speed estimation

This function is used to estimate the sound speed using Coppens equation

sound_speed(T, D = NULL, S = NULL)

Arguments

T	The temperature in degrees C
D	(optional) The depth in meters (defaults to 1 m)
S	The salinity in part-per-thousand (defaults to 35 ppt)

Value

The sound speed in m/s

Note

Range of validity: temperature 0 to 35 °C, salinity 0 to 45 parts per thousand, depth 0 to 4000 m
