New York City is approximately 302 square miles. The 490-square mile glacier broke off the Brunt Ice Shelf, where the British Antarctic Survey’s Halley Research Station is located, the research organization announced. The name might sound a bit boring for the world’s largest iceberg, but it is based on science. An iceberg larger than New York City has broken off an ice shelf in Antarctica, scientists say. The huge chunk of ice is now officially known as the A-76. New giant #iceberg breaking away from the Ronne Ice Shelf 13-05-2021 roughly 160 km x 25 km satellite image from #Sentinel1 /LmacupcuUW- Keith Makinson May 13, 2021ĮSA 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. If Antarctica’s entire ice sheet were to melt, it could raise sea levels by nearly 190 feet. That makes icebergs like this different from glaciers or ice sheets, which are found on land, and which do raise global sea levels when they break off into the ocean and melt. Once it melts, the new iceberg will not lead to a sea level rise, 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. Scientists aren’t attributing this particular break-off to climate change, and instead believe it’s part of the natural cycle of iceberg calving in the region. Iceberg calving is part of the natural cycle, with huge chunks of ice breaking off the ice shelf at regular intervals. NASA is keeping tabs on two other giant cracks in the ice shelf that are growing rapidly. That makes it slightly larger than the Spanish island of Majorca, ESA said. Videos show a 490-square-mile iceberg breaking off Antarctica's Brunt Ice Shelf. 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. The iceberg broke off the western side of the Ronne Ice Shelf in Antarctica’s Weddell Sea, the European Space Agency (ESA) said Wednesday. 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.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. In recent decades, Antarcticas ice shelves have been out of balance, as they have lost more mass to basal melt and calving than has been replenished by the. The name might sound a bit boring for the world’s largest iceberg, but it is based on science.
Scientists aren’t attributing this particular break-off to climate change, and instead believe it’s part of the natural cycle of iceberg calving in the region. In early March, researchers from the British Antarctic Survey took the first aerial photographs of A81, an iceberg the size of Los Angeles that broke off from the Brunt Ice Shelf on Jan. That makes it slightly larger than the Spanish island of Majorca, ESA said. 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.
