World’s biggest iceberg runs aground off remote island

The largest iceberg in the world runs in shallow waters off the British British island in southern Georgia, habitat of millions of penguins and seals.

It seems that the iceberg, which is about twice the size of Greater London, is stuck and must start secession from the beaches of the southwestern island.

Fishermen fear that they will be forced with large parts of the ice, and this may affect some penguins in pasta in the area.

But scientists in Antarctica say huge amounts of nutrients are closed inside the ice, and that during its melting, it can create an explosion in life in the ocean.

“It is similar to dropping a nourishing bomb in the center of an empty desert,” says Professor Nadine Johnston from the British Antarctic Survey.

“If it is separated, it is possible that the resulting ice mountains will pose a threat to the ships while they are moving in local currents and can restrict the arrival of ships to the local fishing lands,” said environment scientist Mark Bilchier, who advises a government south of Georgia.

The Stranding is the latest development in the story of nearly 40 years that started when a huge ice piece separated from the Vilchner-Ronal ice shelf in 1986.

We have followed his way on satellite pictures since December when it was finally liberated after being trapped in the cycle of the ocean.

While moving north through warmer water, nicknamed the ICEberg, it remained significantly intact. For a few days, it appears that he was rotating immediately, before rushing in mid -February at a distance of 20 miles (30 km) a day.

“The future of all the icebergs is that they will die. It is very surprising to see that the A23A has continued this long and only lost about a quarter of its region,” said Professor Haw Griffiths, speaking to the BBC News of the Antarctic Research ship.

On Saturday, the 300 -meter ice was hit by a shallow continental shelf about 50 miles (80 km) of the ground and now it appears to be firmly.

“It is likely that it is likely to stay more or less where it is, until the pieces explode,” says Professor Andrew Megarez from the British Antarctic Survey.

It shows signs of progress on decay. Once a size of 3900 square kilometers (1500 square miles) in size, it was steadily shrinking, attaching huge amounts of water while moving to the warmer seas. It is now estimated at 3,234 square kilometers.

“Instead of a large ice box, you can see caves under the edges,” says Professor Megings.

The tide will now be raised up and down, and as it touches the continental shelf, it will grind back and forward, and lead to the erosion of rocks and ice.

“If the ice is below it is corrupt – it erodes salt – it will collapse under pressure and may be drifted in a more shallow place,” says Professor Megers.

But when ice touches on the shelf, there are thousands of small creatures such as coral, marine mollusks and sponge.

Professor Griffiths says: “Their entire world is exposed to bulldozing through a huge ice board along the sea floor,” says Professor Griffiths.

This is a short -term short -term of these species, but he says it is a natural part of the life cycle in the region.

He adds: “Where he destroys something in one place, it provides nutrients and food elsewhere.”

There were concerns about the creatures of the largest islands. In 2004, it influenced a iceberg in a different area called the Russian Sea on the success of the capsule breeding, which led to a rise in deaths.

But experts now believe that most birds and animals in southern Georgia will escape this amount.

Peter Fritrever says in the British Antarctic Survey that some pasta pencils can be affected by Peter Fritrever in the British Wiping in the British Antarctic that some pasta pencils that Boutros Fritrever can be affected in the British Southern Pole.

The ice melts fresh water in salt water, which reduces the amount of food, including krill (small cortical) that the penguins eat.

He explains that birds can move to other feeding land, but that will put them in competition with other creatures.

The ice can prevent ports or sailing when the fishing season begins in April.

“This will be the most ice of an iceberg we will deal with it at all in the hunting season, but we are well prepared and resources,” says Andrew Newman of Argus Freianis.

But scientists who work on the Antarctica currently also discover the amazing contributions made by Icebergs to the life of the ocean.

Professor Griffiths and Professor Johnston are working on the Sir David Attenburo ship to collect evidence of what their team believes is a large flow of nutrients from ice in the Antarctica via Earth.

Scientists show that particles and nutrients from all over the world are trapped in the ice, which are slowly released in the ocean.

Professor Griffiths says: “Without ice, we will not have these ecosystems. They are some of the most productive systems in the world, support huge numbers of individual species and animals, and feeding the largest animals in the world such as the blue whale,” says Professor Griffiths.

A sign that this release of the nutrients has started around the A23A will be when the vast vegetable plankton pools bloom around the ice. It will look like a vast green aura around the ice, visible from satellite images in the coming weeks and months.

The lifestyle of the icebergs is a natural process, but climate change is expected to create more icy mountains with a high temperature of Antarctica and becomes more stable.

More can be separated from the wide ice sheets on the continent and melt at faster rates, which disrupts wild lifestyles and fishing in the area.
