NASA this week published close-up photos of a giant iceberg that said it was "three times the size of Manhatten."
The photos were taken in the organization's Operation IceBridge and mark the first time anyone has seen the berg named B-46 by the American National Ice Center.
The giant mass broke from the Pine Island glacier (PIG) at the end of October.
Pine Island Glacier in West Antarctica is known for the availability of icebergs in the Amundsen Sea, according to NASA, but the frequency of these events seems to be on the rise
The photos were taken on a flight last Wednesday as part of a long campaign to collect annual ocean ice, glaciers and critical ice scattering
On 29 October, the National Ice Hockey Center estimated the area of the B-46 at 66 square nautical miles (226,374km²).
The satellite images of the IceBridge flight showed that the main iceberg had already begun to break down.
Pine Island and the nearby Thwaites Glacier contribute about 1 millimeter per decade to the global rise in sea level, according to NASA.
