Recent studies and eye-witness accounts have seen a drastic increase in the amount of icebergs breaking away from Antarctica. This has been caused by the increase in global warming, with a retreat in the ice shelf surrounding mainland Antarctica.
However one bit of good news is making its way out of this, with scientists recently discovering an unexpected abundance of life surrounding these floating mammoths of ice in the Weddell Sea, part of the Antarctic's Southern Ocean. The ice shelves which used to extend roughly 3900 square-miles over the Weddell Sea completely disappeared by 2002.
It was in this sea that Shackleton's ship, the Endurance was trapped and crushed by ice in 1915.
