Instrument Tracking for Ocean Acoustic Tomography Experiments

Abstract

Ocean acoustic tomography is a method for measuring the sound speed structure of a volume of ocean indirectly using the transmission of sound between instruments deployed within the area of interest. Since acoustic tomography is based on the measurement of travel time of transmitted signals, the data are very sensitive to the relative displacement of the instruments. This paper describes a navigation system which continuously tracks ocean acoustic tomography instruments. By this system, the contaminating effect of mooring motion on the measurement of travel times of acoustic signals is removed. Australia.
