Short-period internal waves in the frontal zones of non-tidal seas (the Black Sea and the Aegean Sea)

Abstract

This paper reports empirical data on short-period internal waves in the Black Sea and Aegean frontal zones, collected through the use of distributed temperature sensor arrays. Peculiar features of the behaviour and propagation of the internal waves in these zones are shown. It is shown that the wavefield is anisotropic and reduction of the wave lengths diminishes during the climb up a sloping pycnocline. The energy level of the spectra of internal wave oscillations in the frontal zones of non-tidal seas was found to be lower than that relating to oceanic frontal zones.
