Inter-annual variability of acoustic ray travel times in the northeast Pacific
Furgerson, John A.
MetadataShow full item record
An 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.

(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1950-07)The tides of coastal embayments derive their energy from the ocean tides rather than from the direct action of lunar and solar gravitational forces. They are considered to be part of co-oscilating systems in which the ...
