In a few special places glaciers can extend tens of kilometres into the ocean – giant fingers of ice several hundred metres thick, pointing out into the sea. On reaching the sea, these glaciers fracture and release icebergs or form large regions of floating ice known as ice shelves. Snow falls on the continent and over time it has built up layers of ice which flow in glaciers towards the coast.
