AML Oceanographic offers calibrated sound velocity sensors in the following ranges, measured in metres per second. For an explanation of the relationship between precision and accuracy, please see below.
Sound velocity varies as a function of pressure,
temperature and salinity. Most open ocean conditions see sound
velocities of between 1400 and 1550 metres per second. That said, under
extreme conditions of temperature - for example, in the Persian Gulf -
or depth - for example, in the Marianas Trench - sound velocities may
move beyond this standard range. The graph below depicts
environmental conditions and their corresponding sound velocity ranges.
