The Wilkins Ice Shelf is at risk of partly breaking away from the Antarctic Peninsula as the ice bridge that connects it to Charcot and Latady Islands looks set to collapse. The beginning of what appears to be the demise of the ice bridge began this week when new rifts forming along its centre axis resulted in a large block of ice breaking away. The Advanced Synthetic Aperture Radar (ASAR) images acquired on 2 April by ESA's Envisat satellite confirm that the rifts are quickly expanding...

A large ice shelf is near collapse in Antarctica, held together only by a small strip of ice as global warming continues to alter the map of the frozen continent. "We've come to the Wilkins Ice Shelf to see its final death throes," glaciologist David Vaughan of the British Antarctic Survey (BAS) told Reuters after his red Twin Otter plane landed near the shelf's narrowest section. "It really could go at any minute," he said, adding that the ice bridge could linger weeks or months. The large,...

In light of recent developments that threaten to lead to the break-up of the Wilkins Ice Shelf, ESA is making daily satellite images of the ice shelf available to the public via the 'Webcam' from Space web page in order to monitor the developments as they occur. The Wilkins Ice Shelf, a broad plate of floating ice off the coast of the Antarctic Peninsula, has undergone many changes in 2008. Due to the warming in the Antarctic spring (late November), newly formed rifts were discovered that...

U.S. scientists say they've created a computer program to help predict when icebergs will calve from ice sheets. The models we have do not currently have any way to figure out where the big ice sheets end and where the ice calves off to form icebergs, said Penn State Professor Richard Alley. The problem, he said, is the great variability involved in iceberg calving. One important variable -- the one that accounts for the largest portion of when the iceberg breaks -- is the rate at which ice...

New rifts have developed on the Wilkins Ice Shelf that could lead to the opening of the ice bridge that has been preventing the ice shelf from disintegrating and breaking away from the Antarctic Peninsula. The ice bridge connects the Wilkins Ice Shelf to two islands, Charcot and Latady. As seen in the Envisat image here acquired on 26 November 2008, new rifts (denoted by colorful lines and dates of the events) have formed to the east of Latady Island and appear to be moving in a northerly...

Scientists from University of Edinburgh and the British Antarctic Survey said Thursday they will visit a vulnerable area of the Antarctic shelf later this year to determine if it might break apart and trigger a rise in sea levels in the coming years. The team will drill into the ice and use radars on the Larsen C ice shelf, located on the Antarctic peninsula nearest South America. In 1995, Larsen A, a chunk of the shelf, broke off. Another part, Larsen B, broke away in 2002. The remaining...

Scientists said on Tuesday the ice shelves in Canada's High Arctic have lost a colossal area measuring 19 square miles after it broke away last month. The remaining shelves attached to Ellesmere Island, which have lasted for thousands of years, have seen almost a quarter of their cover break away. The Markham Ice Shelf, one of just five remaining ice shelves in the Canadian Arctic, split away from Ellesmere Island in early August.  Scientists also reported that two large chunks totaling...

The Wilkins Ice Shelf is experiencing further disintegration that is threatening the collapse of the ice bridge connecting the shelf to Charcot Island. Since the connection to the island in the image center helps to stabilize the ice shelf, it is likely the break-up of the bridge will put the remainder of the ice shelf at risk. This animation, comprised of images acquired by Envisat's Advanced Synthetic Aperture Radar (ASAR) between 30 May and 9 July 2008, shows the break-up event which began...

Wilkins Ice Shelf has experienced further break-up with an area of about 160 km² breaking off from 30 May to 31 May 2008. ESA's Envisat satellite captured the event "“ the first ever-documented episode to occur in winter. Wilkins Ice Shelf, a broad plate of floating ice south of South America on the Antarctic Peninsula, is connected to two islands, Charcot and Latady. In February 2008, an area of about 400 km² broke off from the ice shelf,...

A vast ice shelf hanging on by a thin strip looks to be the next chunk to break off from the Antarctic Peninsula, the latest sign of global warming's impact on Earth's southernmost continent. Scientists are shocked by the rapid change of events. Glaciologist Ted Scambos of the University of Colorado was monitoring satellite images of the Wilkins Ice Shelf and spotted a huge iceberg measuring 25 miles by 1.5 miles (41 kilometers by 2.5 kilometers) that appeared to have broken away from...
