DESCRIPTION:Internal waves are responsible for significant mixing in the o
 cean and distribute energy through a variety of mechanisms. Triadic resona
 nce instability (TRI) is one such mechanism\, in which an internal wavebea
 m above a critical amplitude emits two 'child' internal wavebeams. We inve
 stigate how interaction with a vortex ring can trigger this instability at
  a lower amplitude than the critical\, and show some experiments trying to
  understand which aspects of the vortex ring are causing the collapse.
