Acoustic tomography

From Glossary of Meteorology

acoustic tomography

An imaging technique in which information is collected from beams of acoustic radiations that have passed through an object, generally in the form representing a two-dimensional slice through the object.

In oceanography, acoustic tomography consists of an inverse technique that uses acoustic signals to sample the interior of the ocean. In this way, the temperature structure of the interior ocean can be reconstructed from acoustic signals in multiple vertical planes.
