Inter-annual variability of acoustic ray travel times in the northeast Pacific
Submitted in partial fulfillment of the requirements for the degree of Master of Science at the Massachusetts Institute of Technology and the Woods Hole Oceanographic Institution September 1990An acoustic tomography experiment consisting of a source near Hawaii and seven receivers
along the west coast of North America was conducted from November 1987 to May 1988
and from February 1989 to July 1989. In this thesis, the acoustic ray travel times are
analyzed in order to investigate inter-annual basin-scale thermal variability. These thermal
fluctuations may help detect any greenhouse warming and greater understanding of them
will increase knowledge of ocean-atmosphere interactions which affect weather and climate.
A discussion of the program for finding the travel times is included along with a comparison
of two methods of measuring travel times
