Estimates of spectral wave attenuation in Antarctic sea ice, using model/data inversion

A model-data inversion is applied to an extensive observational dataset collected in the Southern Ocean north of Ross Sea during late autumn early winter, producing estimates frequency-dependent rate dissipation by sea ice. The modeling platform WAVEWATCH III® which accounts for non-stationarity, advection, wave generation, and other relevant processes. resulting 9477 profiles are co-located with variables such as ice thickness quantify correlations might be exploited later studies improve predictions. An average from cases thinner near edge fitted a simple binomial. binomial shows remarkable qualitative similarity prior observation-based dissipation, power dependence consistent at least three theoretical models, one assumes that dominated turbulence generated shear ice-water interface. Estimated lower closer edge, where thinner, waveheight larger. quantified correlation may develop new parametric predictions dissipation.
