The 490 square miles (1270 square kilometers) chunk of ice is bigger than New York. According to the BAS in the same statement, there is "no evidence that climate change has played a significant role" in this specific event. The 1,255-sq-mile (3,250-sq-km) Larsen B ice shelf was known to be melting fast but no one had predicted that it would take just one month for the 200-metre-thick behemoth to completely. A giant iceberg broke off the Brunt Ice Shelf in Antarctica on Friday, not far from a British scientific outpost. The Brunt Ice Shelf, which typically flows west at about 1.2 miles (2 kilometers) per year, routinely experiences calving events. The team working at the BAS Halley Research Station say that the station is unlikely to be affected by the recent calving event, according to the same BAS statement. It is now the largest iceberg in the world. Sat 03.00 EST Last modified on Sat 03.02 EST Twenty years ago, an area of ice thought to weigh almost 500bn tonnes dramatically broke off the Antarctic continent and. Ice calving, or iceberg or glacier calving, occurs when large pieces of ice break off of a glacier. A massive slab of ice, roughly the shape of Manhattan but more than 70 times larger, has sheared off from Antarctica and floated into the Weddell Sea. At the time, it was the largest iceberg in the world and the sixth-largest berg in three decades of records. In July 2017, Iceberg A-68 broke from the Larsen C Ice Shelf, along the east coast of the Antarctic Peninsula. Ice Charts Data Files Icebergs Ross Outlook Trend Graph Trivariate Synopsis. Arctic Antarctic Great Lakes Mid-Atlantic IMS Snow/Ice. These scientists have been expecting a large "calving event" for at least a decade, according to the BAS. Scientists recently chronicled such death throes for one of the world’s largest-known icebergs. National Ice Center (USNIC) is the global entity that names, tracks, and documents Antarctic icebergs that meet the criteria of 20 sqNM or greater, or 10 NM on its longest axis. (Image credit: British Antarctic Survey)įor years, glaciologists have monitored the cracks that have formed in the Brunt Ice Shelf, a large floating slab of ice 492 feet (150 meters) thick located on Antarctica's northern rim and the site of the British Antarctic Survey's (BAS) Halley Research Station. A map shows the Halley VI research station in relation to the north rift crack.
