Coastal polynyas in the Arctic basin from the winter period (January to April) are characterized using ESA European Remote Sensing satellite (ERS)-1/2 Synthetic Aperture Radar (SAR) Precision (Precise Image, PRI) and Browse images. A SAR polynya algo

The Synthetic Aperture Radars (SARs) on ERS and RADARSAT are sensitive to changes in the small-scale surface roughness present on the ocean surface, which is altered by the velocity field associated with internal waves. More than 2600 SAR images from

RESUMEUn algorithme de concentration de la glace compose d'un ratio moyen, d'un seuil local et d'une methode en ondelettes est applique sur des images RADARSAT et ERS. On discute et l'on evalue les erreurs estimees, qui peuvent etre de l'ordre de que

An ERS SAR PRI coastal polynya classification algorithm is presented for extracting polynya size and shape from the surrounding ice area. The algorithm is based on texture and intensity but also on additional discontinuity information from a 2 dimens
