state of Rhode Island is smaller still, with a land mass of just 2,678 square kilometres (1,034 square miles). That makes it three-quarters the size of P.E.I., which has an area of 5,660 square kilometres, and larger than Spain's tourist island of Majorca in the Mediterranean, which occupies 3,640 square kilometres (1,405 square miles). Its surface area spans 4,320 square kilometres (1,668 square miles) and measures 175 kilometres (106 miles) long by 25 kilometres (15 miles) wide. The newly calved berg, designated A-76 by scientists, was spotted in recent satellite images captured by the Copernicus Sentinel-1 mission, the space agency said in a statement posted on its website with a photo of the enormous, oblong ice sheet. (Copernicus Sentinel data (2021)/ESA, licensed under CC BY-SA 3.0 IGO)Ī giant slab of ice has sheared off from the frozen edge of Antarctica into the Weddell Sea, becoming the largest iceberg afloat in the world, the European Space Agency said on Wednesday. This animation uses images from the Copernicus Sentinel-1 mission and shows the giant slab of ice breaking off from the Ronne Ice Shelf, lying in the Weddell Sea, on. “But what will be interesting to see is how the loss of this ice will influence the ocean melting under the remaining ice shelf and the speed at which the ice flows off the continent.The world’s largest iceberg, dubbed A-76, has calved from Antarctica. “The calving will not directly affect sea level, because the ice shelf was already floating, much like an ice cube in a glass of water,” Dr Galton-Fenzi said. Currently there are instruments deployed on the ice measuring the impact of ocean melt and ice flow.Īustralian Antarctic Program glaciologist, Dr Ben Galton-Fenzi, said they picked up last week’s calving through satellite imagery. Researchers have been studying the Amery Ice Shelf since the 1960s. “We don’t think this event is linked to climate change, it’s part of the ice shelf’s normal cycle, where we see major calving events every 60–70 years,” Professor Fricker added. The last major calving event on the Amery was in 1963–64. The Amery Ice Shelf is the third largest in Antarctica and is located between Australia’s Davis and Mawson research stations.

We knew it would happen eventually, but just to keep us all on our toes, it is not exactly where we expected it to be.” “I am excited to see this calving event after all these years. “We first noticed a rift at the front of the ice shelf in the early 2000s and predicted a large iceberg would break off between 2010–2015,” said Scripps’ Professor Helen Amanda Fricker. Scientists from the Australian Antarctic Program, Institute for Marine and Antarctic Studies and Scripps Institution of Oceanography had been closely monitoring the Amery loose tooth rift system for nearly 20 years. It separated from the ice shelf last week, on the 26th of September, next to a location scientists had been watching known as the “Loose Tooth”, because it appeared to be precariously attached. The tabular iceberg, officially named D-28, is 1636 square kilometres in size, or about 50 × 30 kilometres, about the size of urban Sydney or the Isle of Skye in Scotland.
