# Velocity of sound in sea-water

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

 Formula Del GrossoUNESCO Temperature ℃(0~30)of sea surface [ Salinity ‰ ]
 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?

is the temperature input is the the temperature at that particular depth

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.

how to find the variations in speed of sound for depth less than 1000m

I would like the formula

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.
