[1/5] #iceberg A-23A, né de la plateforme de glace Filchner-Ronne, est aujourd’hui le plus grand du monde avec 3.460 km² soit la taille de l’État de Rhode Island. Resté bloqué des décennies dans la mer de #Weddell il a repris sa dérive dans l’océan Austral en 2020. #geography #icebergtracking
World's Biggest Iceberg
Currently, the largest iceberg in the world is A-23A, with an area of 3,880 square kilometers.

[4/5] La dérive des #icebergs vers le nord est suivie par satellite. Elle peut perturber les écosystèmes : si #A-23A s’échoue durablement, il pourrait bloquer les routes d’alimentation des phoques et manchots autour de la #GéorgieduSud. #geography #icebergtracking #climatechange #southernocean

[5/5] Le suivi des icebergs géants comme A-23A permet de mieux comprendre l’impact du réchauffement sur la cryosphère et les courants océaniques. Ces masses flottantes sont de puissants indicateurs géographiques des bouleversements climatiques. #geography #icebergtracking #climatechange

[3/5] En se fragmentant à cause de l’eau plus chaude, #A-23A a perdu 360 km² en surface. Le plus grand fragment, nommé A-23C, mesure 11 x 14 milles nautiques. Ce phénomène d’ "edge wasting" accélère la disparition des plus grands icebergs. #geography #icebergtracking #climatechange #southernocean

[2/5] Guidé par les courants et les vents, #A-23A a dérivé sur plus de 2.000 km en suivant l’ "iceberg alley" vers l’Atlantique sud. Depuis mars 2025, il est échoué au large de l’île de #GéorgieduSud sur un plateau peu profond à 55°S. #geography #icebergtracking #climatechange #southernocean

An iceberg broke loose in Greenland last summer - massive, unpredictable, and drifting close to cruise routes.
Our researchers followed it from space using satellites, currents, and code.
Here’s how we did it: nersc.no/en/features/...

Icebergs on the move: We develop forecasts for where they are going - NERSC
As global temperatures rise, glaciers around the world are melting faster, including in Greenland. More icebergs are breaking off from glaciers along the
