Iceberg A-68A, the huge frigid behemoth posing a threat to South Georgia Island, could be breaking into pieces. Satellite images from the European Space Agency showed large cracks forming within the iceberg. Now it appears to breaking up.
Iceberg A-68A’s journey started back in July 2017 when it broke faraway from Antarctica’s Larsen C shelf ice. The orbital eyes of satellites of both the ESA and NASA from many years watched its drifting progress. Measuring 5,800 square kilometres (2200 sq. mi.) in area and estimated to weigh one trillion tons, the iceberg spent its first few years on the brink of the Larsen shelf ice before currents swept it along.
It followed a well-trodden iceberg path faraway from Antarctica and toward South Georgia Island, a British Overseas Territory. It had been only about 350 km (217 mi) far away from the island and on a possible collision course by mid-November. And it wasn’t the primary iceberg to be headed straight for the remote island.
In 1998 iceberg A-38 broke away from Antarctica that in the end split into two large pieces named A-38A and A-38B. While A-38A drifted north and broke up within the ocean, A-38B headed straight for South Georgia Island. In the end it broke apart, but a huge block of it became grounded in shallow waters near South Georgia. It got stuck there, blocking access to wildlife feeding grounds and due to which many seal pups and penguin chicks died.
Scientists were worried when A-68A feeding ground when it was heading for South Georgia’s. For one thing, A-68B is far larger than A-38A and is nearly as big as South Georgia itself. It could’ve become the disaster for wildlife if A-68B were grounded near the island.
Then in December, it seemed like the huge iceberg was changing course. Currents were carrying it westward, far away from the island. Hopefully, life would continue as normal for the wildlife of South Georgia Island. Now, the news gets even better: cracks formed in A-68B, and now it’s just like the massive iceberg has split into smaller ‘bergs.
The break-up began in December when an outsized chunk of ice named A-68D broke off. In late of January another block of ice named A-68G broke off. The loss of A-68G spelled the start of the top for the huge iceberg. Soon after, A-68H and A-68I broke away. These all ices have measurement of about 20 km by 9 km and 30 km by 5 km respectively.
Now, A-68A which measures about 60 km by 22 km now that was at just one occasion the most important iceberg, is greatly diminished. And it’s moving far away from South Georgia Island and isn’t expected to pose a threat near about 225 km (140 mi) from the island and drifting south.
