Because of the interaction between ocean wave and sea ice, reliable models for wave propagation in the ice-covered region is critical to sea ice morphology. We present calibration of a viscoelastic type wave-in-ice model with wave, wind, and ice data collected from the Beaufort and Chukchi seas in the autumn of 2015. The data were from multiple sources of in-situ and remote sensing measurements in the marginal ice zone during the ice advance season. We assessed the influence of various ice sources in the model calibration and compared wave hindcasts using the ocean wave model WaveWatch III with in-situ measured wave data in the field studied region. This analysis will be useful in the model calibration and wave forecasts in the interior pack ice field in the Arctic Ocean.
