NASA shares the first images of a massive Antarctic glacier from Pine Island Glacier



NASA this week published close-ups of a giant glacier that said it was "three times the size of Manhattan."

The photos were taken during Operation Icebridge. Of the agency and marked the first time anyone saw the bar, known as "B-46" by the American Ice Center.

The giant mass disengaged from Pine Island Ice (PIG) ​​in late October.

Pine Island Glacier in West Antarctica is known for dividing glaciers into the Amundsen Sea, according to NASA, but the frequency of such events seems to be on the rise

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

On October 29, the National Ice Center estimated the surface area of ​​B-46 at 66 nautical miles (226.374 sq km).

The satellite photographs of Icebridge showed that the main glacier was already falling apart.

Pine Island and the nearby Thwaites Glacier alone are contributing about 1 millimeter per decade to the rise in global sea level, according to NASA.
