On November 24, the world’s largest iceberg broke off in the Weddell Sea, Antarctica and began moving towards the Southern Ocean.

This week, the British research vessel RRS Sir David Attenborough passed by the area where the iceberg is located and recorded unique images from his “journey”.

The A23aas it is called, has an area of ​​about 4,000 square kilometers, an area four times the size of New York, a height of 400 meters and a total of one trillion tons of water.

Mission researchers were also able to take samples from the iceberg, which they hope will help them understand how climate change is affecting the Southern Ocean and the organisms that live there.


Scientists estimate that A23a is moving at a rate of 4.8 kilometers per day and is expected to be driven by the Antarctic Circumpolar Current into Iceberg Alley in the South Atlantic.
