No big deal

B31

Just move along, nothing to see here:

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 Antarctica’s Pine Island Glacier last November, Brunt added.

“It’s one that’s 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 iceberg’s present location is not in an area heavily navigated by ships.

“There’s not a lot of shipping traffic down there. We’re 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.
