Basin-scale tidal measurements using acoustic tomography

Observations of ocean fluctuations between 15 and 23 hour periods in the Pacific

“…Headrick (1990) has analyzed the barotropic tidal signals in the tomographic data, and finds close agreement between the data and models of the diurnal tides. A continuous 110-day data segment is available from four receivers.…”

“…Had it not been for other work demonstrating agreement between the tomographic data and models of barotropic tides (Headrick, 1990), we may have even questioned the validity of the data itself. In one sense, this study highlights the concept that while it is easy to design an experiment to prove or disprove a specific theory, it is much more difficult to find a theory to fit observed phenomena.…”
