Abstract. A reliable knowledge and assessment of the sea ice conditions and their evolution in time is a priority for numerous decision makers in the domains of coastal and offshore management and engineering as well as in commercial navigation. As of today, countless research projects aimed at both modelling and mapping past, actual and future sea ice conditions were completed using sea ice numerical models, statistical models, educated guesses or remote sensing imagery. From this research, rel...

The sea ice cover in the North evolves at a rapid rate. To adequately monitor this evolution, tools with high temporal and spatial resolution are needed. This paper presents IceMap250, an automatic sea ice extent mapping algorithm using MODIS reflective/emissive bands. Hybrid cloud-masking using both the MOD35 mask and a visibility mask, combined with downscaling of Bands 3–7 to 250 m, are utilized to delineate sea ice extent using a decision tree approach. IceMap250 was tested on scenes from th...

Marine infrastructures are a key component for arctic communities. During the past decades, climate change effects have been observed throughout the Arctic and may be linked with marine infrastructure physical deterioration. Changes in the wind and water regimes and in the ice conditions are major factors explaining this observed phenomenon. Satellite radar images are often used to monitor sea ice conditions on a large scale. This study focuses on the use of high resolution radar images to asses...
