Scientists are monitoring an iceberg roughly six times the size of Manhattan -- one of the largest now in existence -- that broke off from an Antarctic glacier and is heading into the open ocean. NASA glaciologist Kelly Brunt said on Wednesday the iceberg covers about 255 square miles (660 square km) and is up to a third of a mile (500 meters) thick. Known as B31, the iceberg separated from Antarcticas Pine Island Glacier last November, Brunt added. Its one thats large enough that it warrants monitoring, Brunt said in a telephone interview, noting that U.S. government organizations including the National Ice Center keep an eye on dozens of icebergs at any given time. The icebergs present location is not in an area heavily navigated by ships. Theres not a lot of shipping traffic down there. Were not particularly concerned about shipping lanes. We know where all the big ones are, she said. Scientists are especially interested in this iceberg not only because of its size but because it originated in an unexpected location, said Brunt.
