The world’s largest iceberg, known as A23a iceberg, is on the move after being grounded to the sea floor since 1986. #iceberg #antarctica #sea | Sky News

L’iceberg A23a est actuellement le plus grand iceberg au monde. Il s’est détaché de la plateforme de glace Filchner-Ronne en Antarctique en 1986. Les scientifiques surveillent sa trajectoire, car il semble maintenant se retrouver pris dans le courant circumpolaire antarctique (ACC), ce qui le dirigerait vers l’océan Austral, où il pourrait éventuellement perturber la navigation. #rtbfinfo #rtbf #A23a #iceberg #glacier #antarctique | RTBF Info

The Final Drift of Earth’s Oldest Iceberg After 40 years of drifting across the Southern Ocean, Iceberg A-23A is nearing its end — and turning a brilliant shade of blue. 🧊💙 Originally the size of a small country, A-23A broke off Antarctica’s Filchner Ice Shelf back in 1986. It stayed grounded for decades, but in 2023 it finally broke loose. Now, as it melts in warmer waters, it's shrinking fast and glowing cyan as meltwater pools deepen cracks in the dense, ancient ice. This color change is mo

The world's largest iceberg, A23a, continues to move through the Southern Ocean this month. In this 3-day loop from Jan. 30-Feb. 2, 2025, we are using the Snow/Cloud imagery from NOAA's GOES East (GOES-16) satellite, which helps the iceberg stand out among the extensive cloud cover. #TimelapseTuesday | NOAA Satellite and Information Service

A23a, once the world’s largest iceberg, is rapidly breaking apart in the South Atlantic Ocean. After decades grounded on the seabed since it calved from Antarctica’s Filchner Ice Shelf in 1986, it began drifting again in 2020, and now, it’s disintegrating into countless fragments. As spring arrives in the Southern Hemisphere, the iceberg’s story comes to an end, melting away piece by piece. 🌍 #A23a #Antarctica #EarthFromSpace | Sen
