ICEBERG A68a
An enormous iceberg that is heading toward the island of South Georgia in the
southern Atlantic Ocean has broken up into three large chunks. Scientists from NASA
have been tracking the berg - dubbed A68a - for several weeks. It actually calved from
the Larsen C ice shelf in 2017 and has been floating northwards ever since. 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. Scientists say the three fragments are roughly 2,600 square
kilometres in size. The submerged part of one chunk is 106 metres at its thickest point.
The sheer bulk of the three iceberg chunks poses a serious threat to the wildlife of
South Georgia. There could be an environmental catastrophe waiting to happen. If the
three mini icebergs collide with the seabed, they could obstruct penguins and seals from
foraging for fish. They could also block the route between penguin colonies and their
feeding grounds during the breeding season. Scientists worry the underside of the
fragments could grind the seabed near South Georgia and disrupt delicate underwater
ecosystems. This could be exacerbated by the introduction of a mass of fresh water to the
ecosystems as the stationary fragments melt over the summer months.
