Spectral analysis was used to investigate semidaily mean sea
levels and atmospheric pressures at San Francisco, California,
Coos Bay, Oregon, and Tofino, British Columbia, in the frequency
band 0 to 0.5 cpd. Cross spectral analysis of semidaily mean sea
levels and atmospheric pressures at the three stations show that the
response of sea level to low-frequency atmospheric pressure fluctuations
is nonbarometric in the frequency band studied, and varies with
season. Cross spectral analysis of semidaily mean sea levels between
adjacent stations shows that there exists significant coherence
between the Coos Bay and Tofino sea levels within the frequency band
studied and phase difference between the stations is consistent with
the hypothesis of continental shelf waves traveling from south to
north along the coast. / Graduation date: 1970
