Latest Drygalski Ice Tongue Stories
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.
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.
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.
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 â€“ large and permanent enough to feature in Antarctic atlases - has come off worst.
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.
Envisat radar imagery confirms that the B-15A iceberg â€“ the world's largest floating object â€“ 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.
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.
Car demolition derbies last minutes, but when it comes to a giant iceberg near Antarctica it takes a bit longer.
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 planet.
