A pulse sonar system is described for measuring the height above the
bottom of an underwater camera and other equipment in the deep oceans.
Using this method, cameras have been positioned for photography at depths
to about 2,500 fathoms with a precision of about half a fathom. The measurement
is achieved by a sonar "pinger" on the equipment, which sends
precise 1 pulse-per- second signals to the surface both directly and by reflection
from the bottom.

Acoustic scattering from density and sound speed gradients : modeling of oceanic pycnoclines
(Acoustical Society of America, 2011-12-20)A weak-scattering model that allows prediction of acoustic scattering from oceanic pycnoclines (and the accompanying sound speed gradients) based on hydrographic profiles is described. Model predictions, based on profiles ...
