According to a release by the BAS, the ice shelf has been slowly floating into the ocean for some time now. Larsen A broke down in 1995, and Larsen B in 2002, while the Larsen C Ice Shelf broke away in July 2017 and produced an iceberg A-68 the size of Luxembourg. Although the iceberg is massive, ...
In 2007, marine ecologist Julian Gutt of the Alfred Wegener Institute led an expedition to the Larsen B ice shelf to study the seafloor that had emerged from its ice shadow five years earlier. The researchers found strange new species, but also discovered that some pioneering critters had already moved in ...

It looks like the Larsen-C story might not be over yet.” As a reminder, following a similar event that saw the calving of a large iceberg back in 2002, the Larsen B ice shelf completely collapsed over a relatively short period of time — the calving event serving as the destabilization that set the whole collapse in ...
The huge iceberg that detached from the Larsen C ice shelf is travelling away from it, according to scientists that are tracking it. And ice shelf is continuing to change after the iceberg detached, with more cracks appearing in its surface. The Larsen C ice shelf lost 10 per cent of its surface when one of the ...
One of the world's largest icebergs broke off from Antarctica's Larsen C ice shelf and attracted global attention this week, but the Larsen shelf's deterioration has been in progress for more than two decades. Its dramatic decline is documented in successive images from National Geographic Atlases of the ...
After months of expectation, a gigantic piece of the Larsen C ice shelf broke off Antarctica sometime between Monday and Wednesday, scientists at the Swansea University-led Midas project announced Wednesday. The final split was detected by NASA's Aqua satellite and freed a trillion ton iceberg into the ...

One of the largest icebergs ever recorded is about to break off an Antarctic ice shelf and float away. The separation of roughly 10 percent of the Antarctic Peninsula's Larsen C ice shelf—equivalent in size to the state of Delaware—from the main body is imminent. The “calving” event, as scientists call the ...
In the largest jump since January, the rift in the Larsen C Ice Shelf has grown an additional 17 km (11 miles) between May 25 and May 31 2017. ... the rift, and that Larsen C may eventually follow the example of its neighbor Larsen B, which disintegrated in 2002 following a similar rift-induced calving event.
That loss will alter ice shelf dynamics and could speed the demise of the rest of the ice shelf, similar to what happened to neighboring Larsen A and Larsen B. The Larsen ice shelf complex is located on the Antarctic Peninsula, a roughly 800-mile stretch of land sticking out in the Southern Ocean like a ...
An ice shelf is a floating slab of ice, attached to land, that is formed by a glacier or ice stream running down a coast into the water.
As we reported previously, the soon-to-occur calving of the enormous iceberg won't lead to any major impacts itself, but it serves as a sign that the whole Larsen C Ice Shelf may collapse within the near future - as has happened to other ice shelves ...
Experts from British Antarctic Survey (BAS) have seen many further cracks and abysses form between the parent ice shelf and the huge iceberg that is in the process of giving way.
When Larsen B collapsed in 2002, scientists watched as warmer air turned melt pools into lakes on the surface of both Larsen A and B, while warmer seawater temperatures eroded the shelf from below.
This second process was clearly in play when the Larsen B ice shelf, positioned just to the north of Larsen C, collapsed in 2003, but I am not sure that this has been a factor for the Larsen C. In the case of Larsen B, there were clearly large bodies ...
That's what happened when icebergs broke away from the Larsen A and Larsen B ice shelves in the past. The glaciers flowing into Larsen C are enough to raise global sea levels by a centimeter -- much, much more than the usual three millimeters they rise ...
Scientists have been keeping an eye on the growing rift in Larsen C for years after the collapse of the Larsen A ice shelf in 1995 and the break-up of the Larsen B shelf in 2002. It is not unusual for ice shelves to produce iceberg every few decades ...
When the ice shelf calves, this iceberg will be one of the largest ever recorded. Exactly how long this will take is difficult to predict.

A MASSIVE crack which can be seen splitting Antarctic Peninsula's ice shelf will cause an iceberg twice the size of Wales to crumble into the sea.
In a May 2015 study published in The Cryosphere, an inter-European group of scientists mapped the flow and velocity of Larsen B's feeding glaciers between 1995 and 2013 during which the ice shelf had calved and then gradually disintegrated. Combining ...
The break-off could destabilize inland glaciers on the continent, and contribute to already rising global sea levels. Several other ice shelves have collapsed in the northern parts of Antarctica in recent years, including the Larsen B ice shelf which ...
Galen Halverson of McGill University captured this photo from the deck of the research ship Nathaniel B. Palmer, in Antarctica's Weddell Sea.
The nearby Larsen A and B ice shelves collapsed in 1995 and 2002, respectively, and the glaciers held back by Larsen B have flowed faster into the ocean ever since.
He mentioned that Larsen A broke off in 1995 and Larsen B spread over 3,200 square kilometers and 220 thick split in 2002. The focus of the scientists has now shifted towards the implications of this break-off.
In 1995, a 579-square-mile (1,500 square kilometers) chunk of Larsen A broke off from the ice shelf, according to NASA's Earth Observatory.
Larsen A, the most northern of the three segments, and the smallest, broke free from the mainland in 1995. The larger Larsen B Ice Shelf, an estimated 3,200 square kilometers of ice with an average thickness of 220 meters, disintegrated into the sea in ...
To put this in context, before breaking away, Larsen B ice shelf had been stable for more than 10,000 years. Since breaking away, the many glaciers held back by the ice shelf have accelerated their melting into the ocean, according to Adam Booth of the ...
WASHINGTON (AP) - Scientists are watching, but not alarmed by, a growing crack at the edge of a key floating ice shelf in Antarctica.
WASHINGTON (AP) - Scientists are watching, but not alarmed by, a growing crack at the edge of a key floating ice shelf in Antarctica.
As a reminder, the "nearby" Larsen B ice shelf disintegrated completely back in 2002 following a similar event. Also, recent research has found that the ice shelfs of East Antarctica are much less stable than previously thought, and could collapse ...
However, a rapid ice shelf collapse would not be unprecedented. In 2002, a large piece of the nearby Larsen B Ice Shelf snapped off, but within a month - and quite unexpectedly - an even larger swath of the 10,000-year-old feature behind it rapidly ...
Scientists are worried that Larsen C, which is 10 times the size of Larsen B and the fourth biggest ice shelf in Antarctica, could eventually follow in its neighbors' footsteps, though they don't think it will destabilize as quickly because it hasn't ...
The UK based Project Midas which is monitoring the Larsen C ice shelf in West Antarctica has warned that a rift on the shelf extended by 18km in the second half of December 2016 and is "poised to calve".
WASHINGTON (AP) - Scientists are watching, but not alarmed by, a growing crack at the edge of a key floating ice shelf in Antarctica.
The current event is not an ice shelf collapsing, but Larsen C may, in years or decades to come, follow the course of the Larsen B Ice Shelf which splintered and collapsed in the space of a month in 2002, they said. Ice shelves hold back the ice on the ...
The nearby Larsen A ice shelf collapsed in 1995, and Larsen B dramatically broke up seven years later. The ice block currently separating from Larsen C contains about 10 percent of its mass, and would be among the 10 largest break-offs ever recorded, ...
... of ice and cause a massive iceberg to break off. While this is a natural process, there is concern that when it occurs, it could usher in a period of irrevocable retreat and possibly lead to the ice shelf's demise further contributing to the rise ...
Peneliti sudah mencatat perpecahan di Larsen C selama beberapa tahun,dan menunggu dengan kecemasan setelah runtuhnya kawasan es Larsen A pada 1995 dan perpecahan secara tak terduga di Larsen B pada 2002. Tahun lalu,peneliti dari Project Midas Inggris ...
Researchers have been tracking the rift in Larsen C for many years, watching it with some trepidation after the collapse of Larsen A ice shelf in 1995 and the sudden break-up of the Larsen B shelf in 2002. Last year, researchers from the UK's Project ...
When the Rhode Island-sized Larsen B ice shelf on the Antarctic Peninsula collapsed over five weeks the glaciers behind sped up by a factor of eight (luckily the Peninsula isn't big).
But the collapses of Larsen A ice shelf in 1995 and Larsen B in 2002 were violent events, documented by human witnesses and satellite photos.
The collapse of an ice shelf provides a one-of-a-kind scientific laboratory, said Phil Trathan, a scientist at the British Antarctic Survey and one of the authors of the proposal.
Project MIDAS, a U.K. group dedicated to studying the Larsen C shelf, notes that a warming climate has changed the structure of the ice, threatening the possibility of collapse.
... clear examples are found of collapsing protective ice shelves around the West Antarctic Peninsula, for instance the iconic collapse of the enormous Larsen B shelf into the Weddell Sea in 2002 (following the collapse of the smaller Larsen A ice ...
In 1995 the Larsen A ice shelf disintegrated, before Larsen B broke up in 2002. Now, Midas - a team of scientists aiming to observe and track the changes in the Antarctic - have noticed a rapid break in the Larsen C ice shelf. In March 2016 they noted ...
... in the Larsen C ice shelf, which can be found on the northern end of the Antarctic Peninsula, for two years already. And if the project's findings are correct, Larsen C could undergo the same fate like that of its neighbors Larsen A and Larsen B ...
According to the study, the last remaining section of Larsen B ice shelf, which partially collapsed in 2002, is flowing faster, becoming increasingly fragmented and developing large cracks.
The Larsen C Ice Shelf is the most northerly of the remaining major Antarctic Peninsula ice shelves. This part of Antarctica has been warming rapidly in recent years, due to a combination of increasing air and sea temperatures.
... phenomenon has been observed in East Antarctica, the researchers say - though it was previously spotted on the warmer Antarctic Peninsula and was likely part of what drove spectacular events there like the shattering of the Larsen B ice shelf in 2002.
In March, I joined the 2041 expedition to Antarctica on a two-week mission, led by polar explorer Robert Swan, to learn about climate change and to see the continent firsthand.
The splintering of the Larsen B ice shelf in 2002 inspired the opening scene of a Hollywood disaster movie about climate change, The Day After Tomorrow, where a vast crack destroys a US scientific camp.
