Using old satellite radar techniques, scientists have developed a new way of measuring the true extent of an understudied and crucial region of the Antarctic sea-ice system for the first time. The Marginal Ice Zone (MIZ) around Antarctica is the "outer edge" of the sea ice, forming a nearly 200-kilometer-wide ring of ice floes affected by waves from the extremely rough Southern Ocean.
