The iceberg's present location is not in an area heavily navigated by ships.
WASHINGTON 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.
They say the iceberg has floated across Pine Island Bay, a basin of the Amundsen Sea, and will likely be swept up soon in the swift currents of the Southern Ocean.
"There were a couple of occasions early on when there might have been partial grounding or collisions with the sea floor, as B31 bounced from one side of the bay to the other," Bigg said.
down there. We're not particularly concerned about shipping lanes. We know New Gucci Trainers where all the big ones are," she said.
"We are doing some research on local ocean currents to try to explain the motion properly. It has been surprising how there have been periods of almost no motion, interspersed with rapid flow," iceberg researcher Grant Bigg of the University of Sheffield in England said in a statement from NASA Earth Observatory.
Scientists are especially interested in this iceberg not only because of its size but because it originated in an unexpected location, said Brunt.

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. government organizations including the National Ice Center keep an eye on dozens of icebergs at any given time.

Pine Island Glacier has been closely studied over the past two decades because it has been thinning and draining rapidly and may be an important contributor to sea level rise, scientists say.
iceberg was first detected in 2011, according to Brunt, a scientist with NASA Goddard Space Flight Center and Morgan State University in Maryland.
