While their results for the. Antarctica’ s ice loss on the rise 11 December Three years of observations by ESA’ s thickness CryoSat satellite show that the West Antarctic Ice Sheet sheet is losing over 150 cubic kilometres of ice each year – thickness considerably more than when last surveyed. 5 million cubic kilometres ( antarctic 6 400 000 cubic miles) of ice. The ice sheet varies in thickness, with the East Antarctic antarctic sheet much higher than the West Antarctic sheet. It is thickness the second largest ice body antarctic in the world, after the Antarctic ice sheet. Ice Antarctica has 70% of all the world' s freshwater frozen as ice - and 90% of all antarctic the world' s ice. The West Antarctic Ice Sheet is divided from the East Antarctic Ice Sheet by the large Transantarctic Mountains. ) shows how ice thickness across the Antarctic continent is variable with thin ice over the mountains thick ice over East Antarctica. Around 90 percent of the fresh water.

The Antarctic ice sheet is the largest single mass of ice on Earth. At its deepest point it can go up to 3 miles nearly 15 000 feet. The Antarctic Ice Sheet refers to the blocks of ice at antarctic the Southern Ocean. 30 ( Zwally et al.
It covers about 98% of the antarctic Antarctic continent and is the largest single mass of ice on Earth. This map shows average changes in the thickness of the Antarctic ice sheet over the last decade. An ice core of 2237 m deep was discovered in 1981 southeastern Greenland.
Most of the West Antarctic Ice Sheet is grounded below sea level, in places over 1. 5 miles below sea level. These two ice sheets cover all but 2. 4 percent of Antarctica' s 14 million square kilometers. At its thickest point the ice sheet is 4, 776 meters deep. It averages 2, 160 meters thick, making Antarctica the highest continent.
