An enormous iceberg that is toward the island of South Georgia in the southern Atlantic Ocean has up into three large chunks. Scientists from NASA have been the berg - A68a - for several weeks. It actually from the Larsen C ice shelf in 2017 and has been northwards ever since. In recent weeks, a fast-moving stream of water known as the Southern Antarctic Circumpolar Current Front has the chunks on a trajectory that they could 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 106 metres at its thickest point.

The sheer bulk of the three iceberg chunks a serious threat to the wildlife of South Georgia. There could an environmental catastrophe to happen. If the three mini icebergs with the seabed, they could penguins and seals from 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 the seabed near South Georgia and delicate underwater ecosystems. This could exacerbated by the introduction of a mass of fresh water to the ecosystems as the stationary fragments over the summer months.
