Increased economic activity and research interest in the Arctic raise theneed for better wave forecasts in the marginal ice zone (MIZ). Mathematical andnumerical models of wave propagation in sea ice would benefit from more in situdata for validation. This study presents shipborne wave measurements from theMIZ where altimeter readings are corrected for ship motion to obtain estimatedsingle point ocean surface elevation. From the combined measurements, we obtainsignificant wave height and zero up-crossing period, as well as one-dimensionalwave spectra. In addition, we provide spectra and integrated parametersobtained from inertial motion units (IMU) placed on ice floes inside the MIZ.The results are compared with integrated parameters from the WAM-4 spectralwave model over a period of three days in the open ocean. We also compare ourmeasurements outside and inside the MIZ with hindcast data from the newpan-Arctic WAM-3 model and the Wave Watch III model for the European Arctic,which both model wave attenuation in sea ice. A good agreement is found withWAM-4 and WW3 in zero up-crossing period and significant wave height outsidethe MIZ, where deviations are less than 23%. WAM-3 is on the other hand up to60% higher than observations. WW3 and WAM-3 are able to estimate the trends forsignificant wave height and zero up-crossing period inside the MIZ, althoughthe discrepancies with respect to the observations were larger than in the openocean. Wave damping by sea ice is investigated by looking at the spatialattenuation coefficients. Predicted attenuation coefficients are found to be72-83% smaller for WW3 and 3-64% larger for WAM-3 compared to observations.Hence, further model tuning is necessary to better estimate wave parameters inthe ice.
