Back in November of 2013, NASA's Terra and Aqua satellites spotted a massive iceberg calving off from Antarctica's Pine Island Glacier. It's taken roughly five months to do it, but this city-sized block of ice has slowly migrated away from the continent, and is now floating out to sea.
According to NASA's Earth Observatory, the estimated size of this iceberg, named B-31, is around 660 square kilometres (33 km long by 20 km wide).
"While some mass was lost very early on in the life of B-31, it has remained pretty much the same shape since early December and is still about six times the size of Manhattan," Grant Bigg of the University of Sheffield, told NASA's Earth Observatory. "Going on measurements of Pine Island glacier before the calving — and hints of partial grounding in the history of the iceberg movement — we think it is possibly 500 meters thick."
That makes B-31 so big that it would completely encase the city of Toronto, with room to spare, and only the last 50 or so metresRead More »from Iceberg six times the size of Manhattan breaks off from Antarctica
