Mammoth iceberg could alter ocean circulation: study
AFP on Yahoo ^ | 2/25/10 | Marlowe Hood

PARIS (AFP) – An iceberg the size of Luxembourg knocked loose from the Antarctic continent earlier this month could disrupt the ocean currents driving weather patterns around the globe, researchers said Thursday.

While the impact would not be felt for decades or longer, a slowdown in the production of colder, dense water could result in less temperate winters in the north Atlantic, they said.

The 2550 square-kilometre (985 square-mile) block broke off on February 12 or 13 from the Mertz Glacier Tongue, a 160-kilometer spit of floating ice protruding into the Southern Ocean from East Antarctica due south of Melbourne, researchers said.

Some 400 metres (1300 feet) thick, the iceberg could fill Sydney Harbour more than 100 times over.

It could also disturb the area's exceptionally rich biodiversity, including a major colony of emperor penguins near Dumont d'Urville, site of a French scientific station, according to the scientists.

"The ice tongue was almost broken already. It was hanging like a loose tooth," said Benoit Legresy, a French glaciologist who has been monitoring the Metz Glacier via satellite images and on the ground for a decade in cooperation with Australian scientists.

The billion-tonne mass was dislodged by another, older iceberg, known as B9B, which split off in 1987.

Jammed against the Antarctic continent for more than 20 years, B9B smashed into the Metz tongue like a slow-motion battering ram after it began to drift.

Both natural cycles and manmade climate change contribute to the collapse ice shelves and glaciers.

Tide and ocean currents constantly beat against exposed areas, while longer summers and rising temperatures also take a toll.

"Obviously when there is warmer water, these ice tongues will become more fragile," said Legresy, who works at the Laboratory for Geophysics and Oceanographic Space Research in Toulouse, southern France.

This is not true unless the iceberg were driving an SUV and exhaling CO2. No way can nature cause anything bad. The world was perfect until someone put humans here. Maybe it was Al Gore’s mom.

Iceberg broke off, probably due to ocean waves, no global warming junk science involved ... But you know they will try, don’t you.

FYI.. this is time at the end of the summer in the Southern Hemisphere that the ice starts to grow again in the Antarctica. Please note that the ice level is slightly above the average since they began satellite measurement of the extent each year:
http://nsidc.org/data/seaice_index/s_plot_daily.html

Also note that total ice has continued to grow (not decrease) since records began:

A, isn't the very definition of a glacier a slow moving river of ice? Well if its moving towards the sea, eventually it will reach the sea and break apart even if the other end is gaining ice... The fact is Antarctica is at record ice levels and the only part of Antarctica that shows signs of warming has an under sea volcano erupting...

None of which points to man made global warming...

Duh...

The largest Antarctic iceberg ever observed was in 1955 by the USS Glacier. The iceberg was twice the size of the state of Connecticut. As far as I recall the weather was not influenced then.

As an aside, the article is bullrohr. Spoken by a physical oceanographer for 30+ years.

Couldn't sleep. I just looked out the front window. Looks like we only picked up about an inch or two on the roof of my car since I got home from work around 6PM.
Noting yet sticking on the streets and pavements, only the grass. The snow looks like it stopped for the time being. Later into the morning hours however after the temps continued to drop we will pick up as you said approx. 6 or so, as heavy bands cycle through. If the roads are not slick as Hanoi John in the early morning I probably will resign myself into going into the pit.
Isn't this the iceberg we read about last month?

While the impact would not be felt for decades or longer, a slowdown in the production of colder, dense water could result in less temperate winters in the north Atlantic, they said.

"Less temperate" means colder. Hmmm, how about that? The earth regulates its own climate in a cyclic fashion.

This article says it was dislodged by another large, twenty year old iceberg ramming against it.

Roughly 50 miles long and 20 miles wide, a mere speck in the ocean.

I just have a feeling that it will break up and melt.

Ice tends to do that when you expose it to warmer water. You don’t need much of a “study” to figure that one out.

An iceberg the size they are talking about in relation to the ocean, would be like throwing an ice cube from your freezer into a swimming pool. I have a very difficult time believing it will make a bit of difference.

I’m sure the people that did this “study” were indeed well paid/rewarded though.....
