| Summary: | Observations between 20 and 40 m depth were made with a towed thermostor
chain in the North Pacific. Despite the rapid vertical variation
of buoyancy frequency, spectra of isotherm displacements are in fair
agreement with other observations and with the Garrett-Munk model. The
spectra show evidence of a shoulder and break in slope at a wavelength
of 1 km. There is no evidence of significant variation of spectral
levels as a function of buoyancy frequency, tow direction, or wind
speed. A peak at a wavelength of 1 km in coherence spectra between
pairs of isotherms separated in the vertical suggests that internal wave
energy at this wavelength is dominated by the low modes. === Graduation date: 1979 |
