This is A23a, currently the largest iceberg on the planet, and after 30 years of being grounded in the Weddell Sea is now drifting north towards South Georgia. This massive tabular berg is 40 nautical miles long, up to 400 metres thick, covers 4000km2 and weighs just short of one trillion tonnes! Simply enormous. The iceberg is showing dramatic signs of erosion as it moves into warmer waters, combined with wave action from the large Southern Ocean swells. Filmed by Richard Sidey & @ianjstrachan

El iceberg más grande del mundo amenaza una isla. Conocido como el A23a, está rumbo a hacer colisión con la remota isla británica de Georgia del Sur, ubicada en el Atlántico Sur. De ocurrir, el choque pone en peligro la vida de pingüinos y focas. Actualmente se encuentra a 280 kilómetros de distancia de Georgia del Sur, cuya soberanía también reclama Argentina. El territorio es un refugio de vida silvestre. Allí podría encallar y romperse en pedazos. En ocasiones anteriores, a consecuencia de ot

🔸El iceberg más grande del mundo encalla cerca de Georgia del Sur El iceberg A23a, el más grande del mundo, ha encallado en aguas subantárticas a unos 73 kilómetros de la isla de Georgia del Sur. Con una superficie de 3.600 kilómetros cuadrados y un grosor de 400 metros, el gigantesco bloque de hielo se desprendió de la plataforma de hielo antártica Filchner en 1986. Su presencia en la zona podría afectar a la fauna local, incluyendo colonias de pingüinos y focas. Toda la información en rtve.es

Previous satellite measurements revealed staggering dimensions—a colossal mass nearing a trillion tonnes, spanning an area of almost 4,000 square kilometres (1,500 square miles) - making it more than twice the size of Greater London - and boasting an average thickness exceedin

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
