World’s largest iceberg breaks off from Antarctica
The world’s largest iceberg has calved from Antarctica over the past few days, a giant floating piece of ice close to 80 times the size of Manhattan.
The European Space Agency said the iceberg broke off the western side of the Ronne Ice Shelf in Antarctica’s Weddell Sea.
The iceberg is shaped like a giant ironing board, measuring around 170 kilometers (105 miles) in length and 25 kilometers (15.5 miles) in width. That makes it slightly larger than the Spanish island of Majorca, ESA said.
Iceberg calving is part of the natural cycle, with huge chunks of ice breaking off the ice shelf at regular intervals, reported CNN. Scientists aren’t attributing this particular break-off to climate change. They believe it’s part of the natural cycle of iceberg calving in the region.
The new iceberg will not lead to a sea level rise once it melts, because it was part of a floating ice shelf — just like a melting ice cube doesn’t increase the level of the drink in your glass, reported CNN.
ESA said the iceberg was first spotted by Keith Makinson, a polar oceanographer with the British Antarctic Survey last week and confirmed from the US National Ice Center using ESA’s Copernicus Sentinel-1 imagery.
The huge chunk of ice is now officially known as the A-76.
The name might sound a bit boring for the world’s largest iceberg, but it is based on science, reported CNN. ESA said icebergs are traditionally named from the Antarctic quadrant in which they were originally sighted, then a sequential number, then, if the iceberg breaks, a sequential letter.
