Giant Iceberg Called More Of A Wonder Than A Worry

WASHINGTON (April 23, 2014) Scientists are monitoring an iceberg bigger than the island of Guam as it slowly drifts away from an Antarctic glacier.

NASA scientist Kelly Brunt said the iceberg is more of a wonder than a worry and is not a threat to shipping or sea level rise.

Brunt said the iceberg, named B-31, is about 255 square miles, roughly six times as big as Manhattan and as much as 1,600 feet thick.

It broke off from the critical Pine Island Glacier last fall and researchers have been watching it move away ever since.

She said it is completely natural for icebergs to split off from glaciers in Antarctica, but this calving does shrink the Pine Island Glacier beyond its 30-year normal.
