After 30 years, it took action: The world’s largest iceberg began its new journey

The world’s largest iceberg, A23a, moved after more than 30 years and started a new journey in the Southern Ocean. The iceberg, which is twice the size of London, weighs approximately one trillion tons and is being closely monitored by scientists.

The world’s largest iceberg, A23a, has moved from its place after more than 30 years and started a new journey in the Southern Ocean.

Experts from the British Antarctic Survey (BAS) confirmed that the iceberg has broken away from its place north of the South Orkney Islands. A23a is now setting out on a new journey, drifting in the Southern Ocean.

Dr. “It’s exciting to see A23a moving again after being stationary for so long,” said Andrew Meijers. “We want to see if it follows the path of other icebergs that have broken off from Antarctica and what impact this will have on the local ecosystem.”
A23a first broke off from the Filchner Ice Shelf in Antarctica in 1986. The giant iceberg, which remained stationary in the Weddell Sea for years, began a slow journey north in 2020. However, in February of this year, it began rotating in place and its movement was delayed due to the Taylor Column phenomenon, which forms on an underwater mountain. Now, satellite images show that A23a has finally broken free of this congestion.
Scientists expect A23a to drift across the Southern Ocean, following the Antarctic Circumpolar Current, and possibly heading towards South Georgia. It is predicted that warmer waters in the region will cause the iceberg to break up and melt.
Researchers have begun work to examine the effects of this giant iceberg on the surrounding ecosystem.
“We know that such giant icebergs can provide nutrients to the waters they pass through and create ecosystems in less productive areas,” said biogeochemist Laura Taylor from BAS. “But we don’t yet know exactly how the size and origin of the icebergs make a difference in this process.”
A23a is being tracked not only by satellites but also by the famous research vessel RRS Sir David Attenborough. Researchers are collecting samples from the waters around the iceberg to understand its effects on the ocean ecosystem and carbon balance.
The giant iceberg’s journey will not only provide new data for ocean science, but also provide important clues about the changing dynamics of Antarctica. Scientists continue to closely monitor the impacts of A23a’s movement on both climate change and ecosystems.
