Strong internal tides in the Kara Gates Strait

We analyze towed CTD measurements, numerical model calculations, and radar images in the Strait of Kara Gates. The measurements were made during an expedition in September 2007. Strong internal tides propagating from the Kara Strait to the Barents Sea were recorded. The internal waves are intensified by the opposite current from the Barents Sea. An internal bore followed by a packet of short-period internal waves is found southwest of the strait. Radar images show that short-period internal waves are generated after the internal bore. A hydraulic jump is found on the eastern side of the strait. Numerical modeling agrees with the experimental results.
