A giant iceberg the size of a small country is floating toward the sub-Antarctic island of South Georgia, raising fears it could indirectly endanger young wildlife.
The British Antarctic Survey said it is concerned the iceberg may run aground near the island, preventing land-based marine predators from reaching food supplies and returning to their offspring.
The giant iceberg, named A68, is about 150km long and 48km wide and has been floating north since it broke off from the Larsen C ice shelf in July 2017, the Antarctic Survey said.
It is about the same size as South Georgia Island, which is currently about 500km away and looks to be in its path.
Professor Geraint Tarling, an ecologist* with the Antarctic Survey, said it is the time of year when seals and penguins are tending to pups and chicks. The distance penguin and seal parents have to travel to find food is important.
“If they have to do a big detour, it means they’re not going to get back to their young in time to prevent them starving to death in the interim*,” he said.
South Georgia, located in the southern Atlantic Ocean, is a British overseas territory.
Apart from being a base for scientific research, it is best known as being the last leg of one of history’s most famous endurance journeys.
Sir Ernest Shackleton, Frank Worsley and Tom Crean became the first people to walk across the island in May 1916.
Their ship, Endurance, had sunk after becoming stuck in ice. Ten months after the ship had become stuck, Shackleton, Worsley and Crean, plus John Vincent, Timothy McCarthy and Harry McNish left the remainder of the ship’s crew on Elephant Island while they rowed 1300km in a lifeboat called the James Caird.
After they landed on South Georgia, Vincent, McCarthy and McNish waited with the lifeboat while Shackleton, Worsley and Crean walked and climbed across mountains and glaciers to the other side of the island to raise the alarm with Norwegian seamen stationed there.
The three men and the lifeboat left on the other side of South Georgia were rescued soon after. The crew left on Elephant Island were finally rescued on September 3, 1916.
