What, where, why?
Antarctica‘s thickest ice is at Dome A in East Antarctica. Here it is 4.8km deep, about as deep as the Alps are high!
Some of the biggest icebergs in the world break off from Antarctica’s ice shelves. One
(B15A) was over 115km long and the same size as Jamaica! Icebergs gradually melt as they drift further away or become grounded in shallow water. Here they can be sculpted by the
waves into amazing shapes and frozen into the sea-ice to form huge towers of ice.
