This is a review paper about measurements of internal tides in the Kara Gates Strait. Kara Gates is one of the straits where intense internal tides are generated by tidal currents overflowing the transversal sill of the strait. Tidal currents are superimposed on a constant current from the Barents to the Kara Sea. Field studies of internal waves in the strait were carried out in 1997, 2007, and 2015. Analysis of measurements on moorings and towed CTD in scanning mode is presented. Field studies are supported by model simulations of generation and propagation of internal tides.
