| Summary: | This presents footage of local horizontal sea ice strain over periods of five minutes or less leading to the creation of ridges under varied degrees of compression and shear. Sound heard in these vignettes is associated with frictional dissipation of kinetic energy during vertical ice displacement. Images shown were recorded during April 2-15, 2007 UTC, as part of the field campaign: Sea Ice Dynamic Nature of the Arctic (SEDNA). Footage and photographs presented in this vignette were taken by Andrew Roberts with the assistance of Jennifer Hutchings and Cathleen Geiger. Funding for SEDNA was provided by the National Science Foundation, grant number OPP ARC 0612527. A precis of SEDNA is available in: Hutchings, J. K. et al. (2008), Role of Ice Dynamics in the Sea Ice Mass Balance, Eos Trans. AGU , 89 (50), doi:10.1029/2008EO500003. This electronic document should be cited as: Roberts, A. F.
