The pressure process by which sea ice is forced into ridges. In the Antarctic, ridges are commonly point features rather than the long linear features observed in the Arctic. A considerable percentage of ice mass is contained within ridged areas of the Antarctic pack. Data from eight voyages into the East Antarctic pack show that by incorporating the ridged ice, the mean thickness increases, on average, by 1.7 times the observed mean undeformed ice thickness.
