The world's largest iceberg, weighing nearly a trillion tons, is drifting in the ocean (video).

Massive ice mountains in the ocean can amaze not only with the lakes on them but also with their size. Iceberg A23a is recognized as the largest iceberg in the world, measuring approximately 3,900 square kilometers and weighing nearly a trillion tons. It began to move several years ago, but in 2024, it found itself "trapped."

Experts from the British Antarctic Survey (BAS) confirmed that A23a has finally shifted from its position north of the South Orkney Islands. In February, the iceberg became stuck in Taylor's Column – a phenomenon where swirling water keeps objects in place.

History of the Iceberg

This massive iceberg broke away from the Filchner Ice Shelf in Antarctica in 1986 but remained on the ocean floor for over 30 years until it started drifting in 2020 due to changes in its buoyancy and ocean currents. A23a is notable not only for its size but also for its thickness of about 400 meters.

Scientific Interest

Scientists are closely monitoring the movement of A23a, as it raises significant questions about its impact on local ecosystems and carbon cycles in the ocean during melting. When it became trapped, water samples were taken around it to understand how great icebergs affect marine life and climate change in the surrounding waters.

Previously, "Telegraph" reported that the ocean is home not only to icebergs but also to millions of tons of plastic. The smallest particles from the water should be extracted by a new Chinese development.
