Acoustical Effects of Internal Tides Acoustical Effects of Internal Tides on Shallow Water Propagation : an Overview of the Intimate96 Experiment
This paper presents an overview of the experiment INTIMATE96, carried out in June 1996 on the continental shelf off the coast of Portugal and discusses the effects of internal tides on the acoustic propagation. A towed broadband acoustic source and a 4-hydrophone vertical array were used. Acoustic data were collected for 5 days, including legs where the source ship was moving and legs with the ...
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 کاملInstability and focusing of internal tides in the deep ocean
The interaction of tidal currents with sea-floor topography results in the radiation of internal gravity waves into the ocean interior. These waves are called internal tides and their dissipation due to nonlinear wave breaking and concomitant threedimensional turbulence could play an important role in the mixing of the abyssal ocean, and hence in controlling the large-scale ocean circulation. A...
متن کاملA model of suspended sediment transport by internal tides
The ability of internal tides to resuspend and advect sediment over continental shelfs and slope regions is investigated by applying an internal wave and sediment transport model. Numerical experiments are carried out, firstly, with the ratio of bathymetry and internal waves characteristics creating critical, subcritical, and supercritical conditions, and secondly, for an observed section of th...
متن کاملIncoherent Nature of M2 Internal Tides at the Hawaiian Ridge
Moored current, temperature, and conductivity measurements are used to study the temporal variability of M2 internal tide generation above the Kaena Ridge, between the Hawaiian islands of Oahu and Kauai. The energy conversion from the barotropic to baroclinic tide measured near the ridge crest varies by a factor of 2 over the 6-month mooring deployment (0.5–1.1 W m). The energy flux measured ju...
