F. auteur aut IRD Haapala J. auteur aut IRD text journalArticle eng We report the detection of bursts of low-frequency waves, typically f=0.025 Hz, on horizontal channels of broadband seismometers deployed on the Arctic sea-ice cover during the DAMOCLES (Developing Arctic Modeling and Observing Capabilities for Long-term Environmental Studies) experiment in spring 2007. These bursts have amplitudes well above the ambient ice swell and a lower frequency content. Their typical duration is of the order of minutes. They occur at irregular times, with periods of relative quietness alternating with periods of strong activity. A significant correlation between the rate of burst occurrences and the ice-cover deformation at the similar to 400 km scale centered on the seismic network suggests that these bursts are caused by remote, episodic deformation involving shearing across regional-scale leads. This observation opens the possibility of complementing satellite measurements of ice-cover deformation, by providing a much more precise temporal sampling, hence a better characterization of the processes involved during these deformation events. specialized 021 064 57 202 231-237 2011 0022-1430 https://www.documentation.ird.fr/hor/PAR00007909 0022-1430 https://www.documentation.ird.fr/hor/PAR00007909 IRD - Base Horizon / Pleins textes 2011-10-06 2017-08-23 PAR00007909 fre
