Making Waves about Sea Ice

Date: 1/7/2014

NIWA scientists made a breakthrough in understanding one of the key processes driving changes in sea ice.
Drs Kohout, Williams and Dean along with Australian based scientist Dr
Meylan researched how the Southern Ocean’s biggest waves affect
Antarctic sea ice. Data shows that waves bigger than 3m in the Southern
Ocean are able to break sea ice over greater distances than previously
believed. This process may be the missing science that explains the
increase in Antarctic, and rapid decrease in Arctic, sea ice extent. The
