Wave Attenuation in the Barents Sea Marginal Ice Zone in the Spring of 2016

Simultaneous field measurements of the motion of several ice floes in the marginal ice zone near Svalbard were performed in April/May 2016 to study the process of wave attenuation in ice. The heave motion amplitudes registered by Inertial Measurement Units (IMUs) deployed on the ice were used to interpret the wave amplitude. Comparison of the wave amplitudes at two different locations gave the wave attenuation coefficient ranging from 0.1×10⁻⁴ to 3.5×10⁻⁴ m⁻¹ for wave frequencies between 0.08 and 0.2 Hz, respectively. This is significantly lower than the attenuation coefficients reported from previous field experiments performed in the same area in 1990, which is perhaps due to the much thinner ice observed in this study compared with the ice in the previous survey.
