​The world’s largest iceberg¹ has moved for the first time in 37 years after being grounded on the sea floor in Antartica since breaking off a glacier² decades ago.

世界上最大的冰山自几十年前从冰川上断裂后，在南极洲的海底搁浅，37年来首次移动。

The A23a is on a journey out of the Weddell Sea following its 1986 grounding, according to the British Antarctic Survey.

据英国南极调查局称，这座A23a南极冰山年搁浅后，正在驶离威德尔海。

The iceberg was dethroned as the largest in the world in 2021, losing the title briefly³ to the A76 iceberg after it broke off from the Ronne Ice Shelf in the Weddell Sea.

2021年，这座冰山从威德尔海的罗恩冰架上脱离后，一度被A76冰山取代，不再是世界上最大的冰山。

But A76 has since broken up into separate pieces, handing the title back to A23a, among the world’s oldest icebergs⁴ as well.

但A76号冰山后来分裂成几个碎片，把世界上最古老的冰山之一A23a号冰山的头衔还给了它。

The iceberg has been drifting for the past year and now appears to be picking up speed and moving past the northern tip of the Antarctic Peninsula, helped by wind and ocean currents.

在过去的一年里，这座冰山一直在漂移，现在在风和洋流的帮助下，似乎正在加快速度，并移动到南极半岛的北端。

The iceberg is about three times the size of New York City and more than twice the size of Greater London, measuring around 4,000 square kilometers (1,500 square miles).

这座冰山大约是纽约市的三倍大，是大伦敦的两倍多，面积约为4000平方公里(1500平方英里)。
