Velocity of sound in sea-water

Calculates the velocity of sound in sea-water and draws the chart.

Velocity of sound in sea-water
Formula
Temperature
    1. ℃(0~30)
    2. of sea surface
[ Salinity
    1. ‰ ]

The Velocity of sound in sea-water changes with water pressure, temperature, and salinity.
It is calculated by the Del Grosso or UNESCO formula.
The temperature of sea water is assumed to be 4 degrees C in the depth of 1000m, and 2 degrees in the depth of 3000m or more.

    Purpose of use
    To determine the speed and distance traveled of micro-bubble bursts in shore wave crashing, to see if this is enough energy at certain depths of sea water to cause micro-organisms to activate their bio-luminescence, thereby creating patterns of light visible over some 80 miles away from an island or shore, which may serve as a navigational aid, as claimed by ancient Polynesian navigators.

    Please can you tell me if the Frequency of sound has any effect on the speed?

    Comment/Request
    is the temperature input is the the temperature at that particular depth
    [6]  2017/05/03 15:16   Female / 20 years old level / High-school/ University/ Grad student / Useful /
    Purpose of use
    project work, to measure actual depth since measured depth may vary due to variations ins speed of sound with salinity, temperature and pressure.
    Comment/Request
    how to find the variations in speed of sound for depth less than 1000m
    [7]  2017/04/14 14:42   Male / 20 years old level / Elementary school/ Junior high-school student / Very /
    Purpose of use
    to calculate the velocity; time taken&depth of the sea
    Comment/Request
    I would like the formula

    Purpose of use
    correctness of measured depth
    Comment/Request
    is the temperature specified is the temperature at measured depth?

    Purpose of use
    Deepwater exploration
    Comment/Request
    Is the velocity reported an average velocity from surface to the specified depth or is it the instantaneous velocity at that depth (and temperature/salinity)? To the geophysicist, these are two very different velocities.
