The data from the X-band high resolution SAR satellite TerraSAR-X (TS-X) and its twin TanDEM-X (TD-X) were used for retrieval of wind and se state parameters in the Arctic. The examples of wind and wave fields under different wind forcing and ice conditions show the strong spatial heterogeneity of the wave field in arctic regions, and the clear need for high resolution spatial wave observations. Other wave information relevant for studying wave-ice interactions are the dampening of the high frequency tail of the wave spectrum, and the modulation of the dominant wave length as the wave field propagates into the marginal ice zone. The performance of the SAR wave retrieval in these aspects will be discussed.
