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

- 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.
