One of the biggest icebergs in recorded history just broke loose from Antarctica
Scientists confirmed Wednesday that very early to the Larsen C ice shelf of Antarctica broke, releasing a huge iceberg of more than 2,200 square miles and weighing one billion tonnes.
In other words, the iceberg – one of the largest recorded history of breaking the ice sheets of Antarctica – is close to the size of Delaware and consists of almost four times more ice than the rapid melting of ice Greenland island Loses in one year. It is expected that the “A68” name will soon receive the names of the scientists.
“Its volume is twice that of Lake Erie, one of the Great Lakes,” researchers wrote with the MIDAS Project, a research group at Swansea and Aberystwyth Universities in Wales that oversees the situation near the satellite.
The iceberg contains so many masses that, if added to the ocean, this would cause almost 3 millimeters of sea level rise (it takes 360 billion tons of ice to produce an increase of 1 millimeter ocean). In this case, however, the iceberg is already afloat, so there will be no substantial change in sea level.
The MIDAS Project Group said on Wednesday that the effect of the failure was reduced by 12 percent on the size of the floating Larsen C ice shelf. Although they are not true, they fear that this could have a destabilizing effect on the platform, which is among the largest in Antarctica.
“The iceberg is one of the biggest advances recorded and its future is difficult to predict,” Adrian Luckman, principal investigator and researcher at the MIDAS Antarctic University of Swansea, said in a statement.
“It can remain in one piece, but is more likely to break into fragments. Some of the ice can remain in the region for decades, while parts of the iceberg can move north into warmer waters.
There is no immediate effect on shipping, Luckman said via email.
“Icebergs in this region sometimes surpass the tip of the Antarctic Peninsula, but it will take time for that to happen on this iceberg or its fragments, and there are not many things I know,” he explained.
Before the break, a crash on the Larsen C ice shelf had surpassed more than 100 miles and a few miles of ice was left connecting iceberg to the platform.
The break started only a few years ago, but has accelerated its pace in the last year, more and more convincing scientists that the iceberg detachment was inevitable, even if it was indeed winter
