Cameras; Underwater photography; SonarAbstract
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.

Deep-sea corehead camera photography and piston coring
McCoy, Floyd W.; von Herzen, Richard P.; Owen, David M.; Boutin, Paul R. (Woods Hole Oceanographic Institution, 1969-03)Cameras were mounted in a newly designed corehead of a piston corer and used to photograph coring operations during 36 stations on CHAIN cruise 75 and 28 stations on ATLANTIS II cruise 42. Through the analysis of these ...
