Sentinel-1 improves understanding of wave-ice interaction in sea ice

Observations derived from Synthetic Aperture Radar imagery show that wave stresses—which can be highly variable—are important external forces on sea ice within a few hundred kilometres of the ice edge.

Southern Ocean sea ice plays a key role in regulating the uptake of carbon and heat by the global ocean. It is known that waves impact the sea ice, including ice break-up and pancake-ice formation. These processes explain large differences in sea ice properties between the Arctic and Antarctic.
