Strong currents have taken hold of a massive Antarctic iceberg that is on a collision course towards South Georgia Island, causing it to shift direction and lose a major chunk of mass, a scientist tracking its journey said on Friday.
The world’s largest iceberg has been captured on camera drifting through the Southern Antarctic Front near the overseas British territory of South Georgia. British Forces South Atlantic Islands (BFSAI) used high-speed digital cameras attached to a military transport aircraft to capture rare images of the iceberg as it travelled towards the island.
An iceberg is heading towards the sub-Antarctic island of South Georgia. A68a – the size of the UK county of Somerset (4,200 sq km) broke off from the Larsen C ice shelf in 2017 and has been drifting north ever since. If it becomes grounded near the island, it could cause disruption to the local wildlife that forage in the food-rich ocean.
A68, a colossus that broke free from the Antarctic in 2017, has pushed so far north it is now at the limit of the continent's perennial sea-ice. When it calved, the berg had an area close to 6,000 sq km and has lost very little of its bulk over the past two and a half years.
The Royal Navy’s Antarctic patrol ship encountered an iceberg the size of Bristol as she began her final scientific mission of the season. HMS Protector came across the enormous mass of ice and snow – 11 miles long and five wide – as she returned to the frozen continent for the last time this winter – or summer as it is in the Southern Hemisphere.
Nasa has released a striking photo of a rectangular iceberg floating in the Weddell Sea off Antarctica. The US space agency said the object's sharp angles and flat surface suggested it had recently broken away from an ice shelf. The edges are still pointed, and have not yet been worn down by the ocean waves.
Antarctica’s Larsen C ice shelf deep crack continues to cut across the ice, leaving a huge chunk clinging on. When it eventually gives way, one of the largest icebergs on record will be set adrift, and whole or in pieces, ocean currents could drag it north, even as far as the Falkland Islands. And if so it could pose a hazard for ships in Drake Passage.
A century after the Titanic disaster, scientists have found an unexpected culprit for the sinking: the moon. Anyone who knows history or has seen the blockbuster movies knows that the cause of the transatlantic liner's accident 100 years ago next month was that it hit an iceberg.
A massive crack is growing wider in the Antarctic ice sheet and could break apart in the coming months, forming an iceberg the size of the island of Lanzarote (Canary Islands, Spain), NASA scientists warned Thursday.
The tsunami caused by the 11 March Tohoku earthquake in Japan crossed the Pacific and broke off large chunks of ice from Antarctica, a study has shown.
