On the calculation of an attenuation coefficient for transects of ice-covered ocean
Published online 24 August 2011 Exponential attenuation of ocean surface waves in ice-covered regions of the polar seas is modelled in a two-dimensional, linear setting, assuming that the sea ice behaves as a thin-elastic plate. Attenuation is produced by natural features in the ice cover, with thre...
