The Ross Ice Shelf is one of many such shelves. It is about the size of France,[1] and reaches into Antarctica from the north. The ice mass is about 800 km (500 mi) wide and 970 km (600 mi) long. In some places, namely its southern areas, the ice shelf can be almost 750 m (2,450 ft) thick. The Ross Ice Shelf pushes out into the sea at the rate of between 1.5 and 3 m (5 and 10 ft) a day. There are other glaciers that gradually add bulk to it. At the same time, the freezing of seawater below the ice mass increases the thickness of the ice from 40 to 50 cm (16 to 20 in)[when?]. Sometimes, fissures and cracks may cause part of the shelf to break off; the largest known is about 31,000 km2 (12,000 sq mi), that is, slightly larger than Belgium.[6] Iceberg B-15, the world's largest recorded iceberg, was calved from the Ross Ice Shelf during March 2000.
University of Colorado's National Snow and Ice Data Center has been studying ice shelves and, in 2002, announced that, based on several break ups of ice shelves, including Larsen B, has begun to reassess their stability. Their scientists stated that the temperature of the warmest portion of the shelf is "only a few degrees too cool in summer presently to undergo the same kind of retreat process. The Ross Ice Shelf is the main outlet for several major glaciers draining the West Antarctic Ice Sheet, which contains the equivalent of 5 m of sea level rise in its above-sea-level ice." The report added that observations of "iceberg calving" on the Ross Ice Shelf are, in their opinion, unrelated to its stability.[5]
