It is expected that in the future it will break up into many smaller ice blocks.

"It's exciting to see the A23a moving again after periods of being stuck. We are wondering if it will follow the same path as other large icebergs that broke off from Antarctica. And more importantly, what impact it will have on the local ecosystem," said Andrew Meyers, oceanographer at the British Antarctic Survey. His words are quoted by the scientific portal Iflscience.

The iceberg is moving with the current around the pole and after a while it will end up near the island of South Georgia. The water here is warmer than in Antarctica as a whole, so the ice megagore will slowly begin to collapse. This process can take decades, and a catastrophic scenario with a relatively rapid melting of such an ice mass is almost incredible.

Iceberg A23a weighs almost a trillion tons and has a size of 3,900 square kilometers (two squares of London with suburbs). Its thickness is 400 m. Megagora broke off from the Filchner–Ronne ice shelf in Antarctica in 1986. Then this block lay motionless at the bottom of the Weddell Sea until 2020, after which the iceberg began to move slowly. At the beginning of 2024, scientists detected its active rotation: the iceberg rotated by 15 ° every day, that is, it made a full turn in 24 days, reports dzen.ru.
