UPDATE:
Well, not really an update, since B15A seems to have stalled out. But, more info at any rate


“The iceberg may have run aground just before colliding. This supports the hypothesis that the seabed around the Drygalski ice tongue is shallow, and surrounded by deposits of glacial material that may have helped preserve it from past collisions, despite its apparent fragility.

“What may be needed to release it from its present stalled location is for the surface currents to turn it into the wind, combined with help from a mixture of wind, tides and bottom melting to float it off its perch.”

Well, folks this my be the last we hear about B15A for a while. They say it has now ground to a complete halt and pose no threat to the penguins or shipping.
Stay tuned.


The plodding course of the Long Island-sized iceberg, which scientists predicted would crash into an Antarctic glacier by 15 January, has been halted indefinitely.

The iceberg, called B-15A, has run aground about four kilometres from the Drygalski Ice Tongue and is "just jiggling back and forth", says Julie Palais, a glaciologist who works at McMurdo Station, a US Antarctic research base. It will probably stay like this for some time, she adds.

Sorry for this off-topic news, but I didn't know where else to put it. As a Norwegian who is not living in Norway I´m very patriotic, you know. I got no english link for you, and I didn't think it was enough to start a new thread...

The Norwegian Queen Sonja came to Antarctica yesterday and will stay there for two days. She is the first Queen to visit Antarctica. Well done, Sonja!
This picture was taken in Antarctica yesterday (if you click it you'll get a norwegian article...) :

After two months of being aground, B-15A is on the move again.
Here's a link with pictures:
www.rednova.com...


Radar imagery from the European Space Agency’s Envisat environmental satellite confirms that the massive B-15A iceberg, which is the world’s largest floating object, is on the move again after spending two months aground.

*snip*
The iceberg became anchored in a shallow seabed earlier this year, but the ESA said tides and currents lifted B-15A free and now prevailing currents are moving it deeper into McMurdo Sound.

see larger image here

Two months ago, B-15A stopped moving when it got caught on a shallow sea bed. In March, local tides and currents set the giant berg adrift again.

This latest development poses a renewed threat to the nearby pier of land-attached ice known as the Drygalski ice tongue.

The sheer scale of B-15A is best appreciated from space. The bottle-shaped Antarctic iceberg is around 120 kilometres long, with an area exceeding 2500 square kilometres, making it about as large as the entire country of Luxembourg.

This was dissapointing. I was expecting to see something spectacular but all I saw was a little bit of ice crack
. LOL I dunno if thats the be crash they were talking about but I expected to see somethign simliar to a car crash with ice flying everywhere.

Well, those ice cracks are the size of florida if not bigger.
What happens when all that ice fall into the ocean?

I must be underestimating the size of the dang thign then
. I guess since i see it on such a small scale it doesnt register as amazing.

I think I'm making this my little project. Here's the latest update:


The threat of sea access being blocked to US and New Zealand bases in Antarctica may have receded after the world's largest iceberg broke free from the McMurdo Sound sea bed last month, New Zealand Antarctic officials said.

*snip*
The previous position of the iceberg had caused a build up of sea ice in McMurdo Sound, threatening access by US ice-breaking ships to New Zealand's Scott Base and the nearby US McMurdo Sound base.

Some scientists have given up predictiing where B15A will go next and are still concerned about where this iceberg will end up.

B15A collided with the tip of the Crygalski ice tongue a couple of days ago.
Maps of Antartica will need to be amended:
www.rednova.com...
Stay tuned for further updates




An image acquired by Envisat on 15 April 2005 shows that a five-kilometre-long section at the seaward end of Drygalski has broken off following a collision with the drifting B-15A.

The iceberg itself appears so far unaffected. With more than half the iceberg still to clear the floating pier of ice, Drygalski may undergo more damage in coming days.

Geeesh, I LIVE in New Zealand for *#&*@& sake and we don't get coverage of this on the news????? GEESH!

It can crash all it wants as long as it doesn't melt. I live not far from the beach and I'm not interested in a rising sea level party!

Iceberg takes bite out of Antarctica

I think this is a rewrite of the same event, but the image is different. I'm very curious to see if other damage will be done!


BTW, don't feel bad about not getting any news! If it weren't for ATS, I think we'd all be in the dark

Obviously, without ATS, I wouldn't have known the damn thing exists! lol gawd. I'll have to keep watch here since we're obviously not gonna find out about it thru the media here! They're too busy reporting on our police force being caught with thousands of porn images lol

It just gets better by the minute!......not

Thats been briefly covered here In Aus as well... Its funny how NZ is one of the o#rys affected by this (i.e your antarctic base was cut off) but you guys didnt hear about it...

Well, it finally happened. Although the light is poor beacause of winter's approach at the erath's southern tip, MODIS thermal bands reveal the outline of the iceberg and the ice tongue.
FWIW, the berg's movement will soon stop due to the winter approaches and the sea freezes.


The giant B-15A iceberg has menaced the Drygalski Ice Tongue since December 2004. At 122 kilometers (76 miles) in length by 28 kilometers (17 miles) in width, the bullying iceberg charged with great momentum towards the ice tongue, threatening to shatter the floating extension of the Davis Glacier.

A scant five kilometers from Drygalski, B-15A ground to a stop, most likely grounded in the shallower waters near the shore. In the weeks that followed, the iceberg rotated free, until finally it began to drift past the ice tongue into the Ross Sea. Just when it looked as if Drygalski might escape a collision, B-15A delivered a glancing blow, knocking the end of the ice tongue loose.

Just when you thought all was quiet down in Antarctica, B-15A is in the news again

A unique radar, Envisat Advanced Synthetic Aperture Radar (ASAR), is being used to track the bergs movements. It can pierce clouds and can also tell between different kinds of ice.

Measuring around 115 kilometres in length with an area exceeding 2500 square kilometres, the B-15A iceberg is the world's largest free-floating object. It is the largest remaining section of the even larger B-15 iceberg that calved from the Ross Ice Shelf in March 2000 before breaking up into smaller sections.

Since then its B-15A section has drifted into McMurdo Sound, where its presence blocked ocean currents and led to a build-up of sea ice that decimated local penguin colonies, deprived of open waters for feeding. During the spring of this year prevailing currents took B-15A slowly past the Drygalski ice tongue. A full-fledged collision failed to take place, but a glancing blow broke the end off Drygalski in mid-April.

The stretch of Victoria Land coast parallel to B-15A's current position is unusually rich in wildlife, noted for colonies of Adelie penguins as well as Weddell seals and Skuas. If B-15A were to remain in its current position for any prolonged length of time, the danger is that the iceberg could pin sea-ice behind it, blocking the easy access to open water that local animal inhabitants currently enjoy.

Huge iceberg menaces Antarctica

The monster iceberg responsible for breaking off a sizeable chunk of the Drygalski ice tongue in Antarctica is on the rampage again. This time, the Long-Island-sized chunk of ice is .ing towards the ice tongue of the Aviator Glacier, where the latest images (snapped on 18 May) reveal it is .ing rapidly for a collision.


The picture was snapped on 18 May with the Envisat satellite's Advanced Synthetic Aperture Radar (ASAR)

Its huge presence blocked ocean currents, leading to a build up of sea ice that decimated local penguin colonies as the birds could not access the open ocean to feed.

Now it is menacing another stretch of coast, one unusually rich in wildlife. Researchers fear that if the berg stays put for any length of time, it could again lead to a dangerous build-up of sea ice, blocking access to the sea for the local Adelie penguins, Skuas and Weddell seals.

seems like there will be more collisions to come after this one.

Another satellite picture of B15-A and the Drygalski Ice Tongue, Antarctica


Iceberg near Drygalski Ice Tongue, Antarctica

Scientists have been watching for a collision between iceberg B15-A and the Drygalski Ice Tongue, the 70-km-long floating end of the David Glacier in Antarctica. The presence of the 120-km-long iceberg B15-A complicates supply trips to the nearby McMurdo science base, and endangers penguins in the area by blocking their access to the open sea. B15-A, the largest floating object on Earth, has been drifting slowly towards the Drygalski Ice tongue for several months, although its progress has slowed in recent days. The iceberg appears to have run aground on shallow waters near the tongue.
