[ Watch the Video ] Breathtaking images taken from outer-space by NASA's Operation IceBridge -- the largest airborne survey of Earth's polar ice ever flown -- reveal a 19-mile long, 195 ft.-deep crack across a floating ice shelf in Antarctica that could produce the world´s largest iceberg. The rift was first discovered last October, but IceBridge scientists returned soon after to obtain the first-ever detailed airborne measurements of the 310 square mile iceberg calving in...

ESA -- After five years of being the world's largest free-floating object, the B-15A iceberg has broken into smaller pieces off Antarctica's Cape Adare. ESA's Envisat satellite's Advanced Synthetic Aperture Radar (ASAR) is sensitive to ice, and has been tracking the movement of the drifting ice object continuously since the beginning of this year. Its latest imagery reveals the bottle-shaped iceberg split into nine knife-shaped icebergs and a myriad of smaller pieces on 27-28 October,...

ESA -- The mammoth B-15A iceberg appears poised to strike another floating Antarctic ice feature, a month on from a passing blow that broke off the end of the Drygalski ice tongue. As this Envisat image reveals, this time its target is the ice tongue of the Aviator Glacier. First discovered in 1955, and named to mark the work done by airmen to open up the Antarctic continent, the Aviator Glacier is a major valley glacier descending from the plateau of Victoria Land along the west side of...

ESA -- Maps of Antarctica need to be amended. The long-awaited collision between the vast B-15A iceberg and the landfast Drygalski ice tongue has taken place. This Envisat radar image shows the ice tongue "“ large and permanent enough to feature in Antarctic atlases - has come off worst. An image acquired by Envisat on 15 April 2005 shows that a five-kilometre-long section at the seaward end of Drygalski has broken off following a collision with the drifting B-15A. The iceberg itself...

CHRISTCHURCH, New Zealand (AFP) -- The threat of sea access being blocked to US and New Zealand bases in Antarctica may have receded after the world's largest iceberg broke free from the McMurdo Sound sea bed last month, New Zealand Antarctic officials said. Iceberg B-15A -- equivalent in size to Luxembourg -- has started moving again into deeper water after becoming stuck in relatively shallow seas in January. The previous position of the iceberg had caused a build up of sea ice in McMurdo...

ESA -- Envisat radar imagery confirms that the B-15A iceberg "“ the world's largest floating object "“ is adrift once more after two months aground on a shallow seamount. This latest development poses a renewed threat to the nearby pier of land-attached ice known as the Drygalski ice tongue. The sheer scale of B-15A is best appreciated from space. The bottle-shaped Antarctic iceberg is around 120 kilometres long, with an area exceeding 2500 square kilometres, making it about...

WELLINGTON, New Zealand (AP) -- U.S. ships have delivered food, fuel and equipment to Antarctic science bases, despite fears they would not be able to pass through the ice pack formed behind the world's largest iceberg, officials said Thursday. A fuel tanker and cargo ship, following a 94-mile path cut by icebreakers through up to 10-feet-thick ice, has reached a pier in McMurdo Sound, U.S. National Science Foundation spokesman Arthur Brown said. The ice pack was nearly double its normal...

NASA -- Car demolition derbies last minutes, but when it comes to a giant iceberg near Antarctica it takes a bit longer. The Moderate Resolution Imaging Spectroradiometer (MODIS) on board the Terra and Aqua satellites captured images of iceberg B-15A steaming a steady course towards the extended Drygalski Ice Tongue and scientists expected the Long Island, NY sized berg to initiate a colossal collision by January 15. Instead B15A appears to have grounded on a submarine shoal when it was just...

NASA -- What happens when the largest floating thing on the planet crashes? We might find out in a couple of days. NASA satellites have witnessed a 100-mile-long iceberg near McMurdo Research station move like a battering ram toward Drygalski Ice Tongue. "It's a clash of the titans, a radical and uncommon event," says Robert Bindshadler, a researcher at NASA's Goddard Space Flight Center, and if the two giant slabs of ice collide, we could see one of the best demolition derbies on the...
