#A23a is currently the world’s largest iceberg, a colossal slab of ice roughly 1,500 square miles in size that recently broke free after being grounded for decades.
Since 2023, it has been drifting beyond Antarctic waters, captured in a massive rotating ocean vortex known as a Taylor Column.

A 9 km lake on an 11 km long iceberg about 200 km NW of South Georgia. One of the larger satellite bergs of iceberg #A23a following breakups over the last several months. Seen by #Sentinel-2 on 9 January 2026 We took a look in the recent iceberg events is this video➡️: https://youtu.be/GdkSp_8y85Q

Today we check out what happened to #Iceberg #A23a ? It was the largest iceberg in the world but multiple large breakups have left it much smaller, covered in lakes as shooting off east northeast across the southern Atlantic. #A23 https://youtu.be/GdkSp_8y85Q

As the giant #Antarctic iceberg #A23a is currently breaking apart, we created a video about its dance in the water in the last year, including spinning in a Taylor column! Even though A23a is not sea ice, the microwave signature is similar and it shows up in our data! Can you spot it in the video?

A-23A is no longer the largest iceberg in the world.
Since 1986, it measured 4,000 kilometres and today it measures approximately 1,700 kilometres, losing 80% of its mass.
It is estimated that from second place in terms of size, it may quickly drop in the rankings.#news #climate #climatechange #a23a #a23aiceberg #iceberg #nature #naturenews #world #mass #size #global #warming #globalwarming #future #data #stat #stats #mass #1986 #2025 #today #emergency #climateemergency #climatechangemergency

"A23a is the size of Oahu, and it's moving into the open ocean in water that is well above freezing, meaning it will break apart quickly in the coming weeks.
This, plus moving ever further north and the coming of southern spring means it is likely to rapidly disintegrate into bergs too small to track further.
Eventually, it will be too small to be seen by satellite — the end of a decades-long era for the scientists who have tracked it."

World’s biggest #iceberg breaks up after 40 years: ‘Most don’t make it this far’
‘Megaberg’ known as #A23a has rapidly disintegrated in warmer waters and could disappear within weeks
A23a calved from #Antarctic shelf in 1986 but quickly grounded in #WeddellSea, remaining stuck for over 30 years. It finally escaped in 2020 and, like other giants before it, was carried along "iceberg alley" into the South #Atlantic #Ocean by the powerful Antarctic Circumpolar Current.

The largest #iceberg in the world #A23a has broken free of the South Georgia sea bed having been grounded there, we take a look and search for the possible storm that released it. #YouStormOutlook #A23 #SouthGeorgia https://youtu.be/aD9NPz-bbiM

World’s biggest iceberg runs aground after a near-40-year journey from Antarctica
The world’s biggest iceberg appears to have run aground roughly 70km (43 miles) from a remote Antarctic island,
potentially sparing the crucial wildlife haven from being hit, a research organisation said Tuesday.The colossal iceberg #A23a – which measures roughly 3,300 sq km and weighs nearly 1tn tonnes – has been drifting north from Antarctica towards South Georgia island since 2020.
This had raised fears it could collide with the island or run aground in shallower water near it,
potentially disrupting the ability of penguins and seals to feed their young.It remains unclear whether the iceberg is stuck for good.
The gigantic wall of ice has been stuck 73km from the island since 1 March, according to a statement from the BAS.
“If the iceberg stays grounded, we don’t expect it to significantly affect the local wildlife,” Meijers said.
“In the last few decades, the many icebergs that end up taking this route through the Southern Ocean soon break up, disperse and melt,”
added Meijers, who encountered A23a in late 2023 and has tracked its fate via satellite ever since.The world’s biggest and oldest iceberg calved from the Antarctic shelf in 1986.
It remained stuck for more than 30 years before finally breaking free in 2020,
its lumbering journey north sometimes delayed by ocean forces that kept it spinning in place

Tierparadies wohl gerettet: Weltweit größter Eisberg läuft auf Grund
Er ist so groß wie Mallorca und drohte, ein Tierparadies zu gefährden: Doch nun ist der weltweit größte Eisberg auf Grund gelaufen. Forschende hoffen, dass sich die Eismassen nicht wieder in Bewegung setzen.

Nice article, this. Interesting to see where the big berg has been for the last few years. I expect there's some fascinating research taking place (more than disclosed in the article).

Iceberg A23a is moving again. @pierre_markuse used to post a lot of great images of this iceberg when it first calved...

Weltweit größter Eisberg setzt sich in Bewegung
Der wohl größte #Eisberg der Welt ist Jahrzehnte nach seinem Abbrechen vom antarktischen #Schelfeis auf dem Weg nach Norden. Das teilte das Polarforschungsinstitut British Antarctic Survey mit. #A23a hatte sich 1986 vom Filchner-Ronne-Schelfeis in der #Antarktis gelöst, hing aber noch jahrzehntelang am Meeresboden fest.
