(Corporal Phil Dye/Ministry of Defence via AP)LONDON – A team of scientists will set off next month on a research mission to find out the impact of a giant floating iceberg on the wildlife and marine life on a sub-Antarctic island, the British Antarctic Survey said Tuesday. Scientists are concerned about the risks it poses to the wildlife in the area if it grounds near the island. The research ship RRS James Cook is expected to depart from the Falkland Islands for the iceberg in late January. Povl Abrahamsen, who is leading the mission, said it normally takes years to plan such marine research trips.

A giant iceberg the size of the U.S. state of Delaware is floating toward the sub-Antarctic island of South Georgia, raising fears it could indirectly endanger young wildlife. The giant iceberg, named A68, has been floating north since it broke off from the Larsen C ice shelf in July 2017, the Antarctic Survey said. South Georgia, located in the southern Atlantic Ocean, is a British overseas territory.

LONDON – A giant iceberg the size of the U.S. state of Delaware is floating toward the sub-Antarctic island of South Georgia, raising fears it could indirectly endanger young wildlife. The British Antarctic Survey said Wednesday 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. 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.
