Geophysical research, acoustics and hydroacoustics
Large thermostratified experimental tank (20 m long, 4 m wide, and 2 m deep) is designed for scale modeling of the wave processes in the upper ocean and the ocean – atmosphere surface layer. It implements a unique method for temperature stratification of the water layer to retrieve a typical profile of the deep-water dependence of the water temperature in the real ocean at about 1:100 ratio. The tank is equipped with a high-speed direct-flow wind-wave channel for modeling a wide range of wind speeds (up to hurricane conditions).
