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

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/...

[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

[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

[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

World's Biggest Iceberg Currently, the largest iceberg in the world is A-23A, with an area of 3,880 square kilometers.

[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
