We present a 19 days, high frequency record
of temperature profiles above the eastern shelfbreak of the Great Meteor Seamount.
Seamounts are known to be efficient regions for internal tides generation, but also
participate in mixing and transport through nonlinear processes and wave breaking. We
measured extreme overtuning events associated with the upgoing tidal flux pushing cold
water up the slope. Strong shear also lead to small scale instabilities that are also
resolved by our sensors
