Scientists worry the underside of the fragments could grind the seabed near South Georgia and disrupt delicate underwater ecosystems. They could also block the route between penguin colonies and their feeding grounds during the breeding season. If the three mini icebergs collide with the seabed, they could obstruct penguins and seals from foraging for fish. There could be an environmental catastrophe waiting to happen. The sheer bulk of the three iceberg chunks poses a serious threat to the wildlife of South Georgia. The submerged part of one chunk is 106 metres at its thickest point. ![]() Scientists say the three fragments are roughly 2,600 square kilometres in size. In recent weeks, a fast-moving stream of water known as the Southern Antarctic Circumpolar Current Front has put the chunks on a trajectory that means they could run aground off the coast of South Georgia. It actually calved from the Larsen C ice shelf in 2017 and has been floating northwards ever since. ![]() Scientists from NASA have been tracking the berg - dubbed A68a - for several weeks. An enormous iceberg that is heading toward the island of South Georgia in the southern Atlantic Ocean has broken up into three large chunks.
