NASA released close-up shots of a huge iceberg this week, which was said to be "three times the size of Manhattan."

The images were taken as part of Agency's Operation IceBridge and mark the first time anyone has seen the mountains designated as the B-46 by the US National Ice Center.

The huge mass broke off at the end of October from Pine Island Glacier (PIG).

According to NASA, the Pine Island Glacier in West Antarctic is known to release icebergs in the Amundsen Sea, but the frequency of such events appears to be increasing

The photos were taken last Wednesday as part of a long-term campaign to capture sea ice, glaciers and critical areas of the Earth's ice sheets

On October 29, the National Ice Center estimated the area of ​​the B-46 to be 66 square miles (226,374 km²).

The satellite images of the IceBridge flight showed that the main iceberg was already breaking apart.

The island of Pine Island and the nearby Thwaites Glacier alone contribute about 1 millimeter per decade to global sea-level rise, according to NASA.
