The dynamics of ocean waves in polar regions give us important clues about the behaviour of sea ice in those areas, according to researchers.
“The ice floes bend with the waves, and over time you can imagine that this creates fatigue and eventually the ice will fracture. Interestingly, the fractures tend to be perpendicular to the direction of the waves, and to be of even widths.”
Re the Arctic, a related BBC report notes ‘that wave heights are going to change with increasing distance from the ice edge to the land, and that could have more of an impact on ice break-up.’
Could that suggest a ‘feedback effect’: greater distance to land = more ice break-up etc.?
