An iceberg almost twice the size of Atlanta has been discovered moving towards the Antarctic Ocean, according to CNN (04/22/14).
Scientists from NASA’s Earth Observatory report that the city-sized iceberg, known as iceberg B31, covers 255 miles and can be a third of a mile thick.
The iceberg detached from Antarctica’s Pine Island Glacier last November and went towards the Amudsen Sea off the western side of the continent. However, the first crack on B31 was spotted in 2011.
To date, the largest iceberg had been B15 which was almost the size of Connecticut or Jamaica, with an area of 4,250 square miles. B15 has broken up already, but parts still remain in and around the Antarctic Ocean.
"The iceberg is now well out of Pine Island Bay and will soon join the more general flow in the Southern Ocean, which could be east or west in this region," iceberg researcher Grant Bigg from the University of Sheffield in England said in a NASA statement.
Should the iceberg continue its current course, researchers are worried they will not be able to spot the iceberg during the dark winter of Antarctica. According to University of Southampton scientist Robert Marsh, the iceberg is not expected to melt for a year or more.
