The principal results deduced from observations of internal waves in the ocean are discussed. Each of the measurements shows either the period or the wave length; hence, it follows that the nature of the detected waves cannot always be determined accurately. Besides it is not always possible to ascertain whether the observed variations are due to waves, vorticity or turbulence. Standing waves seem to occur at the continental slope. The analysis of periods, in particular, led to the suggestion that internal tides and inertia oscillations may predominate; according to measurements carried out in the Northern Atlantic, the wave lengths vary from 25 to 50 km. The maximal amplitude recorded is 300 meters. Variations of several hundred meters in accordance with the tidal rhythm and possibly, with (still unknown) periods of some importance which may be conditioned by meteorological processes, seem to occur frequently in the North Atlantic.
