PARIS -- A vast iceberg that broke off Antarctica earlier this month could drift through the ocean for several years before it breaks up and melts away, a scientist from the European Space Agency said Friday.
Mark Drinkwater, a senior scientist at the space agency, said that while icebergs regularly calve from Antarctic ice shelfs, the region where A-76 broke off had seen relatively little change in recent decades. “We’ve seen icebergs that can last up to 18 years that have been tracked around Antarctica if they remain in relatively cold waters,” he said. “But it’s likely that once this thing gets ejected from the Weddel Sea out into the South Atlantic, it’ll disintegrate fairly quickly.”
