"Was wir beim Überfliegen des größten #Eisbergs der Welt, #A23a, gelernt haben – und warum er nicht mehr lange zu leben hat.
...Es erstreckt sich bis zum Horizont – ein weißes Feld, so weit das Auge reicht."

What we learnt flying over the...
A23a seems to be stationnary in front of the South Georgia island, at approx. 70 kilometeres from the coast.
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

Weltgrößter Eisberg auf Grund gelaufen
Der nach Schätzungen größte #Eisberg der Welt dürfte nördlich der #Antarktis auf Grund gelaufen sein. Der Eisberg sei offenbar in der Nähe von Südgeorgien zum Stillstand gekommen und, teilte das Polarforschungsinstitut #BritishAntarcticSurvey mit.
Der Eisberg #A23a hatte sich 1986 vom #FilchnerRonneSchelfeis in der Antarktis gelöst, hing aber noch jahrelang auf dem Meeresboden fest. Nach dem Loslösen im Jahr 2000 blieb er lange in zirkulierenden Meeresströmungen gefangen.
Der Eisberg ist rund 4.000 Quadratkilometer groß, was in etwa der Fläche des Burgenlandes entspricht. Im Dezember hatten Forscher mitgeteilt, dass sich der Eiskoloss in Bewegung gesetzt hat.
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.
"... scientists working in Antarctica currently are also discovering the incredible contributions that icebergs make to ocean life."

The crash of A23a with the South Georgia island is getting closer and closer... Still I could imagine that scratching the NW-tip of the island could alleviate a bit the ecological damage. But still, the mass of fresh water will create a total disbalance of the local ecosystem.

After a period of relative stagnation, A23a has activated its travel booster and is now progressing towards South Georgia Island at a speed of 15 to 20 kilometers per day. Hopefully, it will bypass the northern tip of the island, or at the very least, only affect a small segment of the island's shoreline.
A23a remains in position at approximately 300 km from the South Georgia island. That's good news, and at the same time it continues to lose mass now down from 3'128 km2 five days ago to 2'897 km2 yesterday.

"現在、氷山は海流に乗ってサウスジョージア島に向かって移動しているとみられる。
マイヤーズ氏は２３日、ＣＮＮに寄せた声明で、「現在、氷山は海流の蛇行上にあり、島に直接向かっているわけではない」と述べた。「しかし、私たちが理解している海流の動きに基づけば、氷山はまたすぐに島に向かって移動する可能性が高い」

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).
