Última The straits of Gibraltar and Kara Gates: a comparison of internal tides ArchiMer Morozov, Eg; Parrilla-barrera, G; Velarde, Mg; Scherbinin, Ad. Moored current measurements, numerical model calculations, and satellite images from the straits of Gibraltar and Kara Gates are compared. The vertical internal displacements (double amplitudes) with a semidiurnal frequency are extremely large in both straits. The displacements are related to internal tidal waves over the sills. The energy of the internal tides is transferred to an internal bore and associated wave packets of short-period internal waves. Their surface manifestation can be seen on the satellite images. Numerical modeling shows that the outflowing current from the Mediterranean Sea to the Atlantic Ocean has a significant influence on internal tides. In the Kara Gates, the flow from the Barents Sea to Kara Sea has a similar influence. The...

The dynamical mode decomposition (DMD) technique is applied to the data of currentmeter and CTD measurements taken during the 1985-1986 Gibraltar Experiment and the 1989 survey so as to clarify features of the vertical structure of the M(2) and S(2) tidal currents at the Camarinal Sill. It is shown that in conformity with the inference made on the basis of the empirical orthogonal function (EOF) decomposition technique, these currents are mainly due to the M(2) and S(2) barotropic modes. At the same time the first three baroclinic modes are responsible not only for the vertical variability of the tidal currents but also for the velocity acid density amplitude variances at semidiurnal frequencies. Certain quantitative discrepancies between the values of...
