Other calving events presaged the breakup of nearby ice shelves. It is likely to follow the path of A74 in the Antarctic Coastal Current.Īlso Read | Earth's core has suddenly stopped spinning. The iceberg is set to break off an ice shelf located in the fastest-warming region of Antarctica, which is likely no accident. The finger-shaped chunk of ice, which is roughly 105 miles (170 kilometers) long and 15 miles. C-02 was the second iceberg to break off the C quadrant since tracking began. An enormous iceberg, a little bigger than the state of Rhode Island, has broken off of Antarctica. It further broke into a second iceberg (A-57b), which kept breaking up and eventually deteriorated. For years, scientists have tracked as chunks of the glacier. JanuA huge iceberg about the size of Delaware is about to break off from the ice shelf in Antarctica. A-57a was the 57th iceberg to break off the continent’s A-quadrant since tracking began in the early 1970s. Researchers said that new iceberg formed along the line of Chasm-1 and is slightly larger than A74. 19, 2020, 7:58 PM UTC By Tom Metcalfe Antarctica’s Pine Island Glacier is one of the most closely watched pieces of ice on Earth. The crack, known as Halloween Crack, was detected some 17 km to the north of the research station across the route sometimes used to resupply Halley. Our science and operational teams continue to monitor the ice shelf in real-time to ensure it is safe, and to maintain the delivery of the science we undertake at Halley," Professor Dominic Hodgson, BAS glaciologist added.Īnother crack has also been detected on the ice shelf and was first picked up in 2017. The iceberg, known as A76, following a naming. “This calving event has been expected and is part of the natural behaviour of the Brunt Ice Shelf. An iceberg nearly half the size of Puerto Rico that broke off the edge of Antarctica last week is now the world’s largest, researchers said. The crack on Antarctica has grown an additional 11 miles (17 kilometers) in just the last week. The main message is it's part of a natural cycle," Alex Brisbourne, a glaciologist at the British Antarctic Survey, said.Researchers maintain that the crack has continued to grow since 2015 and, by December 2022 extended across the entire ice shelf, marking the beginning of the calving event.Īlso Read | Scientists to reset 'Doomsday Clock': What is it and how does it work? Enormous Iceberg About to Break Off From Antarctica. "It's not an area that is undergoing any significant change because of global heating. Scientists say global warming has caused a thinning of such shelves, but they differ on whether the latest event can be blamed on climate change. Scientists expect the iceberg to break up and its pieces will circle Antarctica for years or decades rather than drifting northward into shipping lanes. Here's how it looked on 16 May□ /xOVWjidsZw- ESA EarthObservation May 19, 2021Ī-76 was first detected by the British Antarctic Survey and confirmed by the US National Ice Centre based in Maryland using imagery from Copernicus Sentinel-1, consisting of two polar-orbiting satellites. The iceberg was spotted by and confirmed from using #Sentinel1 imagery. A chasm and a crack on the Brunt Ice Shelf in Antarctica are creeping closer and closer to one another, and when the two finally meet, a slab of ice twice the size of New York City will break away. Meet the new cool kid on the iceberg block: the recently calved #A76 is now the biggest iceberg in the world! In January 1995, Larsen A, the northernmost area of the Larsen Ice Shelf, lost about 770 square miles of ice in a storm as a large iceberg broke off farther south.
