Audiovisual Vignettes of Sea Ice Ridging in the Beaufort Sea in 2007

This presents footage demonstrating the scales of sea ice motion involved in creating 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 Experiment - 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.  An overview of the SEDNA field campaign is given 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.
