Iceberg size of DE breaks off Antarctica

It covers an area of roughly 2,300 square miles (6,000 square kilometers), more than twice the size of Luxembourg.

It weighs over a trillion metric tons., which has been monitoring the Larsen C ice shelf, reported the calving happened sometime between July 10 and July 12. The iceberg is described as weighing 1 trillion tons (1.12 trillion USA tons).

Scientists from the Midas Project have been tracking its progress for the past 12 months as it slowly began to crack until it finally broke off of the Larcen C ice shelf, Antarctica's fourth largest ice shelf.

As it widened, there was more pressure, the to-be iceberg dragging at the main ice shelf to break away. "Some of the ice may remain in the area for decades, while parts of the iceberg [may drift north into warmer waters]".

The six-month wait is over: a enormous 5,800-square-kilometer Antarctic ice shelf monitored by scientists finally broke away this week.

Scientists can't link the iceberg's break directly to climate change, because calving is a natural process in any glacier.

Monitor the development of large cracks in the ice Shelf Larsen took more than ten years.

With a thickness of between 200 and 600 meters, the Larsen C floats at the edge of the Antarctic Peninsula, holding back the flow of glaciers that feed into it.

The ice shelf was already floating on the water before it broke, so sea levels will stay the same.

A huge iceberg has officially broken away from Antartica's fourth largest ice shelf, scientists and NASA's Aqua MODIS satellite have confirmed. Land ice floating into the ocean does contribute to sea level rise: For every 360 billion tons of ice that reach the ocean, sea levels worldwide rise by 1 millimeter. The newly created iceberg is likely one of the top ten largest ever recorded, according to the BBC.

The portion of ice shelf that broke off - which according to Vox is about the size of DE - has been tearing away from the icy continent since at least 2010.

Scientists had anticipated the breakup since a massive crack first opened up in the Larsen C ice shelf back in 2014. "We're going to be watching very carefully for signs that the rest of the shelf is becoming unstable", said Dr. Martin O'Leary with Swansea University.
