Strain in shore fast ice due to incoming ocean waves and swell

摘要: Using a development from the theoretical model presented by Fox and Squire (1990), this paper investigates strain field generated in shore fast ice normally incident ocean waves swell. After brief description of its convergence, normalized absolute (relative to 1-m wave) is found as function distance edge for various wave periods, thicknesses, water depths. The squared transfer function, giving relative ability different periods generate ice, calculated, consequences are discussed. then forced with Pierson-Moskowitz spectrum, consequent spectra plotted penetration into sheet. Finally, rms strain, computed incoherent sum strains resulting energy open found. results have implications breakup hence floe size distribution marginal zone.
