Strong and highly variable push of ocean waves on Southern Ocean sea ice

Justin E. Stopa, Peter Sutherland, Fabrice Ardhuin
2018 Proceedings of the National Academy of Sciences of the United States of America  
Our estimates give an average wave stress that is comparable to the average wind stress acting over 50 km of sea ice.  ...  Ocean waves are known to play an important role in ice break-up and formation. In addition, as ocean waves decay, they cause a stress that pushes the ice in the direction of wave propagation.  ...  Using numerical model results over the open ocean gives similar results.  ...
