Abstract: Moored measurements of temperature, salinity, and currents at three moorings that operated for a year in the area of strong tidal currents in the region of the Akselsundet Strait at the mouth of the Van Mijenfjorden on the island of Spitsbergen are analyzed. Tidal currents flowing around an underwater sill in the strait generate intense tidal internal waves. Forced internal waves exist above the underwater slope. Vertical displacements of water particles reach 20 m. Waves rapidly decay as they propagate away from the strait and slope. They are no longer recorded as far as 12 km from the strait. Tidal currents in the strait reach a speed of 3 m/s and form an intense jet when flowing out of it. A strong jet of currents during spring tides presses the instruments on moorings to the bottom. © 2023, Pleiades Publishing, Ltd.
