The presence of an internal tidal bar and intensive internal wave packets with the period of 10-20 minutes were detected from the in-situ data obtained on the White Sea shelf. Along with the standard methods the wavelet analysis was applied to describe the internal wave characteristics. A well-grounded choice of a wavelet basis and its construction method was carried out. Different options of wavelet transformation are shown while describing nonlinear waves.
