Time-dependent assimilation of CTD data to an open ocean Rossby wave model
… surveys taken two months apart during the 1981 Ocean Tomography experiment southwest of Bermuda, a time-dependent ocean state is estimated that evolves from the first to the second survey. The mesoscale motions are modelled by quasi-geostrophic dynamics, and the ocean model state is represented …

Wave scattering from cylindrical fluid inclusions in an elastic medium and determination of effective medium properties
… medium theory is extremely useful for acoustic tomography applications and can be expanded to include other inhomogeneity geometries besides cylinders.

Inverse methods and results from the 1981 Ocean Acoustic Tomography Experiment
Ocean acoustic tomography was proposed in 1978 by Munk and Wunsch as a possible technique for monitoring the evolution of temperature, density, and current fields over large regions. In 1981, the Ocean Tomography Group deployed four 224 Hz acoustic sources and five receivers in an array which fit …

Tomographic observations of deep convection and the thermal evolution of the Greenland Sea Gyre, 1988-1989
… results from the 1988-89 Greenland Sea Tomography Experiment. Thermal evolution of the gyre center divides naturally into three periods: a preconditioning phase (November-January), during which surface salinity is increased by brine rejection from ice formation and by entrainment but in …

Space and time scales of low frequency variability in the ocean
We have contrived a regional model Φ(K, ω, η, φ, λ) for the distribution of low frequency variability energy in horizontal wavenumber, frequency, vertical mode and geography. We assume horizontal isotropy, Φ(K, ω, η, φ, λ) = 2πKψ(k, l, ω, η, φ, λ), with K designating the amplitude of total …
