DESCRIPTION:<span>Co-author: Hayley H. Shen		(Clarkson Univerisity)       
  <br></span><span><br>Regional wave forecasts for the Arctic rely on a goo
 d understanding of wave propagation through sea ice covers. Disagreements 
 among the models and the lack of field validations cause uncertainty in wa
 ve forecasts. A recent viscoelastic ice model has been developed to simula
 te a wide range of ice covers. This model synthesized several previous mod
 els that considered ice covers as a continuum. In this model\, a simple pa
 rameterization is used to include both energy storage and dissipation mech
 anisms. However\, the model has two parameters\, the equivalent elasticity
  and viscosity\, which need to be determined. In this presentation\, we wi
 ll describe the basis of this model\, and its calibration using data from 
 a recent field campaign.</span>
