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. Satell...
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 w...
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 condi...
The continued loss of sea ice in the Northern Hemisphere due to global warming poses a threat on biota and human activities, evidencing the necessity of efficient sea ice monitoring tools. Aiming at the creation of an improved European sea ice extent indicator, the IceMap250 algorithm has been reworked to generate improved sea ice extent maps at 50...
The continued loss of sea ice in the Northern Hemisphere due to global warming poses a threat to biota and human activities, evidencing the necessity of efficient sea ice monitoring tools. Aiming at the creation of an improved sea ice extent indicator covering the European regional seas, the new IceMap500 algorithm has been developed to classify se...

La télédétection est une ressource à la fine pointe de la technologie gagnant à être intégrée à la gestion des défis en milieux naturels et urbains pour faire face, notamment, aux changements climatiques (eau, alimentation, ressources naturelles, navigation, catastrophes, etc.). Le projet NorthSense : L’Arctique vu de l’espace, parrainé par le prog...
Institut national de la recherche scientifique Centre Eau Terre Environnement 490, rue de la Couronne Québec (Québec) G1K 9A9 Présenté à : Agence Spatiale Canadienne Programme de contributions pour la sensibilisation de la jeunesse à l'espace Rapport de recherche no R-1348 31 mars 2012
This map has been created in the project "Variability and Change in the Canadian Cryosphere" . It is the result of the application of an algorithm developed by Catherine Lagacé during her M.Sc. studies at the INRS-ETE. In this algorithm, 3 variables are used : 1) 36,5 GHz Brightness Temperatures, 2) 18,7 GHz Brightness Temperatures, and 3) Water pe...
