Abstract
An experiment on the propagation of flexural-gravity waves was performed in the HSVA ice tank in 2018. Physical characteristics of the water-ice system were measured in different locations in the tank during the tests, with several sensors deployed in the water, on the ice and
in the air. Periodical waves with frequencies of 0.5-1.5 Hz were generated by HSVA wave maker during 10 min in each test. The phase speeds and wave damping associated with anelastic deformations of ice were analyzed in the paper. Elastic modulus of ice was calculated for each wave period from the dispersion equation of flexural gravity waves where measured values of wave frequencies and wave speeds were substituted. Viscous coefficient of ice was calculated after the analysis of wave damping. Obtained values have relatively big dispersion which can be explained by natural variability of ice properties.
