The largest iceberg in the world is going through a melting stage in what may possibly be “the last months of its existence,” according to the international media. BBC. It is worth mentioning that the A23a separated from the Antarctic coast in 1986, but started moving at the end of 2023 after remaining anchored in the sea for 30 years Weddell.

The largest iceberg in the world could disappear
An expedition company ship Eyos was the one that reported the presence of enormous caves and arches, which are a consequence of the thaw, according to the British media. This would be occurring due to the warmth of the air and water on the surface where the A23awhich have been moving away from Antarctica since the end of 2023.

It is worth mentioning that the largest iceberg in the world separated from the Antarctic coast in 1986 and began to move its 4,000 km2 Of surface Some months ago. Currently, it is in the Antarctic Circumpolar Currenton the way to “iceberg alley”, the main ice exit route on the white continent
The constant movement of the enormous mass of ice will determine its oceanic life; However, the BBC has determined that the iceberg’s destiny is to “fragment and wither until it disappears.” According to Strachanexpedition leader of the team Eyos that was on the surface of the A23aicefalls are being “created” in addition to “a constant state of erosion.”
How long will the A23a survive?
The time of existence of A23a It will be determined by the temperatures it passes through during the time it is in motion, because greater warmth in the air or water will cause the creation of ponds due to the melting of ice, which will drain through the iceberg, helping the opening. of cracks that will cause separation.

The BBC predicts that the caves and arches located on the surface of the iceberg will collapse, leaving areas of submerged ice that will end up eating the edges of the immense mass of ice after rising due to its own buoyancy. Something he’s already been through. iceberg D28: It is located in the South Atlantic and has lost about a third of its surface.
“Dramatic and beautiful to photograph”
On Sunday, January 14, a ship from the Eyos expedition company sailed until it approached A23a and placed a drone on it. In this way, the team was able to appreciate the 30 meter high iceberg. “It was dramatic and beautiful to photograph,” said Richard Sidey, Eyos videographer, according to DW. “It’s mind-blowingly big. In fact, I don’t think we can imagine its size; we can only know through science. It’s too big to photograph. It stretches as far as the eye can see in both directions,” he added.
Thanks to the satellite view, the thickness can be measured and the surface controlled, which in certain points exceeds 300 meters. The mass is in question, since it will decrease daily, although scientists estimate that now it would not be far from a billion tons.
After how long did A23a start moving?
The largest iceberg in the world, also known as A23a, began its journey towards the waters of the South Atlantic after having been stranded until 2020 on the shores of Antarctica. The large mass of ice separated from the Antarctic coast in 1986 and had been settled in the Weddell Sea for more than 30 years.
