Wikipedia:
About 98% of Antarctica is covered by the Antarctic ice sheet. The ice sheet is, on average, 2.5 kilometers (1.6 miles) thick. The continent has approximately 90% of the world’s ice (approximately 70% of the world’s fresh water). If all of this ice were melted sea levels would rise about 61 m (200 feet). In most of the interior of the continent precipitation is very low, down to 20 mm/yr; in a few “blue ice” areas precipitation is lower than mass loss by sublimation and so the local mass balance is negative. In the dry valleys the same effect occurs over a rock base, leading to a desiccated landscape..
