The generation of huge amplitude internal waves by the barotropic tide in the Barents Sea at high latitudes is examined using the numerical model of the Euler 2D equations for incompressible stratified fluid. The considered area is located between the Spitsbergen (Svalbard) Island and the Franz-VictoriaTrough as cross-section of 350 km length. There are two underwater hills of heights about 100 - 150 m on the background depth about 300 m. It is shown that intensive nonlinear internal waves with amplitudes up to 50 m and lengths about 6-12 km are generated in this zone. The total height of such waves is huge and they must be considered as a significant factor of the environment in this basin.
