Mode-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 کاملOn 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 کاملDiurnal internal tides detected in the Adriatic
Strong diurnal oscillations, documented by temperature data that were collected along a submarine cliff on the Lastovo Island (southern Adriatic), are studied and compared with sea level and wind measurements at Dubrovnik and Komiža (island of Vis). Three thermistors were deployed at the depths of 15, 22 and 36 m between March 2001 and March 2002. Pronounced diurnal temperature oscillations wer...
متن کاملGeneration of weakly nonlinear nonhydrostatic internal tides over large topography: a multi-modal approach
A set of evolution equations is derived for the modal coefficients in a weakly nonlinear nonhydrostatic internal-tide generation problem. The equations allow for the presence of large-amplitude topography, e.g. a continental slope, which is formally assumed to have a length scale much larger than that of the internal tide. However, comparison with results from more sophisticated numerical model...
