![]() For spatial wave attenuation, there is a significant body of evidence derived from the field experiments showing a power-law dependence of wave frequency cubed (Meylan et al., 2014, Doble et al., 2015, Sutherland et al., 2017, Meylan et al., 2018, Rogers et al., 2020, Thomson et al., 2021). Numerous studies on ocean wave attenuation have shown that the decay rate is exponential in space and decreases with a decrease in wave frequency. As waves propagate through the Marginal Ice Zone (MIZ), they get scattered and attenuated. From 1979 to 2016, a 35% reduction in Arctic summer sea-ice extent, a 15% reduction during winter and an annual decrease of 10% are reported (Palma et al., 2019). In the Arctic, the region of polar sea-ice has diminished over the last decades. The interaction between ocean waves and the frozen ocean is important in many areas, including climate modelling and safe maritime navigation (Kohout et al., 2014, Squire, 2011, Porter, 2019). This matching of exponent suggests that the same mechanism may be responsible for both types of decay. It is shown that the decay rates obtained from the present study match with the exponent three power-law dependence on wave frequency as observed for the decay rates in the marginal ice zone. The decay rates for the first and third modes of sloshing are extracted, even when these two modes are combined. The temporal decay rates of the free-surface wave amplitudes are measured for a small excitation amplitude and different water-depths. The decay rates with the balls are sufficiently greater than the decay rates without the balls and we assume the effect of the balls dominates the decay. ![]() Laboratory experiments are performed to estimate the wave decay rate due to floating balls representing ice floes. The present study is motivated by the need to understand the possible mechanisms for ocean wave decay in the marginal ice zone. The whole code for this tutorial is on my repository.An experimental study is conducted to investigate the frequency dependent decay of free-surface water waves in a sloshing tank with partially-submerged floating plastic balls on the free-surface.
