On the Mapping and Wav enumber Resolution of Line-Integral Data for Observations of Low-Mode Internal Tides
Techniques are developed for using line-integral tomography data to estimate the spectra, maps, and energy of low-mode internal-tide radiation; the extension of these techniques to other phenomena is obvious. Sparse arrays of line integrals over paths 300−1000 km long can generally determine the direction of propagation of semidiurnal radiation well, but the magnitude of the wav enumbers is amb...
متن کاملMode-1 internal tides in the western North Atlantic Ocean
Mode-1 internal tides were observed the western North Atlantic using an ocean acoustic tomography array deployed in 1991–1992 centered on 251N, 661W. The pentagonal array, 700-km across, acted as an antenna for mode-1 internal-tides. Coherent internal-tide waves with O(1m) displacements were observed traveling in several directions. Although the internal tides of the region were relatively quie...
متن کاملScattering and Trapping of Obliquely Incident, Low-Mode Internal Tides off a Continental Shelf and Slope
We demonstrate – using linear scattering theory and an idealized, stratified, rotating ocean domain, with a flat bottom deep ocean and a straight continental slope and shelf – that a high-mode (mode 3) Poincare wave incident on the coastal margin can excite large amplitude leaky coastal trapped waves (CTWs) or leaky edge waves along the coastal margin dependent on the frequency and alongshore w...
متن کاملMapping Mediterranean Altimeter Data with aMultiresolution Optimal Interpolation
2 Abstract. A multiresolution optimal interpolation scheme is described and used to map the sea level anomaly of the Mediterranean Sea based on TOPEX/POSEIDON and ERS-1 data. The principal advantages of the multiresolution scheme are its high computational eeciency, the requirement for explicit statistical models for the oceanographic signal and the measurement errors, and the production of err...
