Why is converting velocity of sound between sea water and pure water important?

Because differences in salinity, temperature, and pressure affect sound speed, converting allows accurate calculation of acoustic distances for navigation and research.

Can I use this conversion for sea water conditions other than 20°C at 10 meter depth?

This conversion is tailored to these specific conditions; using it for different environments may require additional calibration.

What applications benefit from this velocity conversion between sea and pure water?

Applications include sonar ranging, underwater communications, oceanographic measurements, and acoustic instrument calibration.

Key Terminology

Velocity of sound in sea water (20°C, 10 meter deep): The speed at which acoustic waves travel through seawater at 20 °C and about 10 meters depth, influenced by temperature, salinity, and pressure.
Velocity of sound in pure water: The speed at which acoustic waves propagate through freshwater under set conditions, primarily depending on temperature and pressure.
Acoustic travel time: The duration taken for sound waves to travel through a medium, used to calculate distances underwater.
