Speed of Sound in Seawater

Manage Bookmarks
It calculates the speed of sound in seawater and displays the relationship with water depth in a graph.
Calculation Formula
Sea Surface Temperature
℃(0〜30)
[ Salinity ‰ ]
The speed of sound in seawater varies depending on water pressure, temperature, and salinity, and is calculated using either the Del Grosso equation or the UNESCO equation.
Seawater temperature is assumed to be 4°C at a depth of 1,000 m and 2°C at depths of 3,000 m or more. Salinity is also assumed to be constant.
