“Incredible footage has provided a new view of the world's biggest iceberg as it begins its journey out into the Southern Ocean.

The iceberg, called A23a, is around 1,540 sq miles in area – more than twice the size of Greater London (607 sq miles) – and a whopping 1,312 feet thick.

It hit the headlines last week after it began to move, following 30 years stuck to the ocean floor.

Now, the British Antarctic Survey (BAS) has released new video and images captured by the RRS Sir David Attenborough, showing the 'megaberg' stretching out into the distance beyond the research vessel.
……
While A23a originally calved from the Filchner Ice Shelf back in 1986, it remained grounded on the seabed until last week.

On November 24, the megaberg broke free and began moving out of the Weddell Sea sector into the Southern Ocean. …”

Woo hoo! Margaritas for everybody!

I wonder… could this be the largest detached moving object in history ?

I mean, continents move… but are continents “detached”?

Damn, that’s the large economy size.
Wonder how long it’s gonna take to melt.

Well shoot, I was going to go on my first ever cruise, but with the Meg out there I might have to rethink that.

"Southern Ocean" ??

When I grew up there were 4 oceans, and Southern wasn't one of them.

Interestingly, a quick check of Google maps does in fact show Southern Ocean around Antarctica.
I'm assuming the bit of land at the top of the above image is the southern tip of South America/Argentina, so maybe they're using that term until it's confirmed in either the Atlantic or Pacific?

The Southern Ocean (aka Antarctic Ocean) was only fairly recently designated as the fifth ocean. NOAA recognized it in 1999. Other agencies have since followed suit.

And at one point or another the world was flat, the Earth revolved around the Sun, and phlogiston was the stuff that allowed things to burn.

At least one of those is still true.

LOL, I meant Sun revolved around the Earth. It’s hard to keep up with this sciencey stuff.

Maybe we'll grow younger every year?

My, that's a big one....

That's just the tip of the iceberg.

That is a truly massive piece of real estate.

So is this evidence that the ocean levels are indeed rising, or icebergs melting? Or did the berg (pushed by currents?) eventually gouge a trench in the sea floor?

I seem to recall that this iceberg was a cause celeb for the climate alarmist, citing THIS iceberg and its separation from the Antarctic ice shelf as PROOF! of man's catastrophe

That's not an iceberg, it's a 'ThunBerg'! We should nickname it Greta...Just sayin'

Gretaberg!
