            The Ross Ice Shelf  is the largest ice shelf of Antarctica and covers an area of about 520,000 km2, nearly the size of France. The nearly vertical ice front to the open sea is more than 600 kilometres long, and between 15 and 50 metres high above the water surface. Ninety percent of the floating ice, however, is below the water surface.
