| Summary: | International audience The aim of this study is to identify and quantify the controlling factors of rocky coasts evolution on the north shoreof the Brøgger peninsula, northwest Spitsbergen, from the Kvadehuken spit to the foot of the Haavimfjellet (fig. 1), in acontext of climate change (Artic warming) and geomorphological transition (from glacial and periglacial to paraglacialand paraperiglacial systems). The study areas have been study using several methodologies. Aerial photographs from1990 to 2010 have been used to quantify the evolution of top of the cliff and reveal a total loss area of -9752 m² with aretreat rate of -0,06 m/y. Schmidt hammer has been used to study the resistance variability on cliff faces and shows alower resistance in the top of the cliff face on most studied sites. Evolution of the cliff face has been studied usingphotogrammetry from 2016 to 2017 and a thermal camera has been used to highlight facies variability and areas ofweakness.
