DESCRIPTION:We report on the statistical analysis of stratified turbulence
  forced by large-scale waves. The setup mimics some features of the tidal 
 forcing of turbulence in the ocean interior at submesoscales. Our experime
 nts are performed in the large-scale Coriolis facility in Grenoble\, which
  is 13 m in diameter and 1 m deep. Four wavemakers excite large scale wave
 s of moderate amplitude. In addition to weak internal wave turbulence at l
 arge scales\, we observe strongly nonlinear waves\, the breaking of which 
 triggers intermittently strong turbulence at small scales. A transition to
  strongly nonlinear turbulence is observed at smaller scales. Our measurem
 ents are reminiscent of oceanic observations. Despite similarities with th
 e empirical Garrett & Munk spectrum that assumes weak wave turbulence\, ou
 r observed energy spectra are rather attributed to strongly nonlinear inte
 rnal waves.
