Scientists are trying to unravel the cause of the shrinking sea-ice, or ice that floats, on the surface of Antarctica’s Oceans. Currently its much lower than has previously been measured as a September ‘average’.  In fact the area of ice that is missing is about five times the size of the British Isles. 

I can’t imagine how you go about measuring the sea-ice around Antarctica, but whatever way you look at it, we are missing A LOT!
