In the interest of developing an ice-wave radar, JAMSTEC built a small wave-ice tank in the Kashiwa campus of the U. of Tokyo in 2020. The tank is 8 m long, 1.5 m wide, 0.6 m deep, and is equipped with a plunger-type wavemaker. The tank is enclosed in a low-temperature room whose temperature can be reduced to minus 15 degrees. The water is fresh but by agitating the water by waves, a “grease ice” forms overnight. Interestingly enough, under wave forcing, the ice particles form a group. The group size depends on the incident wave amplitude, remarkably resembling the condition based on an existing pancake ice formation theory. The experimental result was also reproduced by a numerical simulation modeling the grease ice with a non-Newtonian fluid. We have also studied radar reflection from the created deformed ice sheet using a 79 GHz FMCW radar. Other experiments include nonlinear wave train evolution under ice, ice breakup by waves, and so forth.
