First siting of deep lee waves: Kaena Ridge, Hawaii



Turbulent mixing in the ocean has important effects on climate and the transport of energy and nutrients. Internal lee waves, which are underwater standing waves that result from a current flowing over a barrier, have become recognized as an important source of mixing in the ocean. Previous studies with remote observations and numerical models have predicted the existence of breaking deep internal lee waves driven by the tide, but until now, none have been observed directly.
