World's biggest iceberg A23a spins in ocean trap (Southern Ocean) 4/Aug/2024

Something remarkable has happened to A23a, the world's biggest iceberg.
For months now it has been spinning on the spot just north of Antarctica when really it should be racing along with Earth's most powerful ocean current.
Scientists say the frozen block, which is more than twice the size of Greater London, has been captured on top of a huge rotating cylinder of water.
It's a phenomenon oceanographers call a Taylor Column - and it's possible A23a might not escape its jailer for years.
"Usually you think of icebergs as being transient things; they fragment and melt away. But not this one," observed polar expert Prof Mark Brandon.
"A23a is the iceberg that just refuses to die," the Open University researcher told BBC News.
Other A23a iceberg stories have been posted on this channel previously as it is so large.
