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!
Icebergs are floating areas of ice which have been calved from either ice shelves or tidewater glaciers. They can be found all around Antarctica ranging from small pieces of ice known as ‘bergy bits’ to huge pieces of ice over 100 km in size. One of the largest icebergs (B15A) was over 115 km long – the same size as Jamaica!
Not all of the floating ice surrounding Antarctica are icebergs. There is sea ice, which is just frozen sea water, but also ice shelves, which are just floating extensions of the ice from the land.
