 )<br></span><span><br>We examine effects of ocean surface waves on the pol
 ar sea ice and ocean using a sea ice-ocean general circulation model NEMO 
 (stands for Nucleus for European Modelling of the Ocean) coupled with the 
 ocean wave model WAM output from model of the European Centre for Medium-R
 ange Weather Forecasts (ECMWF). In the model the wave-ice interactions inc
 lude: ice fragmentation due to break&ndash\;up by waves in the vicinity of
  the ice edge\; wave attenuation due to multiple scattering and non-elasti
 c losses in the ice\, wave advection and evolution of ice fragmentation. W
 e analyse the impact of the waves on sea ice and the upper ocean\, focusin
 g on the marginal ice zone (MIZ) where the wave impacts are the most. The 
 study compares the model results with the observations\, and highlights a 
 need to farther theoretical understanding of sea ice fragmentation and sum
 marise requirements for observational techniques. The study was carry out 
 in the EU FP7 Project &lsquo\;Ships and waves reaching P olar Regions (SWA
 RP)&rsquo\;.</span>
