Sea state parameters such as significant wave height were estimated using the empirical CWAVE_EX algorithm. The aim of the data acquisition was to overcome the lack of in-situ data on significant wave heights in the Arctic by using remote sensing data. Synthetic Aperture Radar (SAR) images from the TerraSAR-X (TS-X) and TanDEM-X (TD-X) satellites were used to obtain high spatial resolution sea state information around Herschel Island, Qikiqtaruk, Yukon, Canada. All ice-free scenes were processed from the entire archive of TS-X/TD-X StripMap mode imagery with a coverage of approximately 30 km x 50 km acquired between 2009 and 2020. For each SAR scene, a sea state file was created as a tab-separated text file in the coordinate reference system EPSG: 4328 - WGS84. The dataset was used to analyse wave heights in the nearshore zone according to spatial variability, seasonality and wind conditions.
