Icebergs from Wilkins Ice Shelf Float Past Latady Island

Icebergs from the desintegrated Wilkins Ice Shelf continue to break away from the Antarctic Peninsula and move into the open ocean.

These icebergs were previously contained by an ice bridge reaching Charcot Island (partially visible, far left), until it shattered about seven weeks ago.

In the full image, the icebergs can be seen floating off in all directions. Many can be observed left of Latady Island (bottom), others towards Rothschild Island (top).

The ice shelf and Latady Island remain connected, however fractures near the border continue to widen.

Loss of Ice from Wilkins Ice Shelf, Antarctica

Since the ice bridge connecting the Wilkins Ice Shelf (center) to Charcot Island (upper left in the full image) broke six weeks ago, the icebergs from the desintegrated shelf have been moving further away from the Antarctic Peninsula.

The ice shelf is still connected to Latady Island (lower left),  although fractures in the area have formed and widened.

According to the European Commission, researchers predict that the northern edge of the ice shelf will continue to discharge icebergs over the coming weeks, and it is expected to lose between 570 and 3,370 square kilometres of ice. This loss might be even greater if the connection to Latady Island is broken as well.

More Icebergs Break Off Unstable Wilkins Ice Shelf

Wilkins Ice Shelf, one month ago - April 8th, 2009

One month ago

More and more icebergs continue to break away from the Wilkins Ice Shelf and the Antarctic Peninsula.

Fracture zones have been forming over the last fifteen years; however a bridge of ice connecting the ice shelf to Charcot Island (top left corner in both images) prevented most icebergs from breaking off completely and floating out into the open ocean.

The smaller image is from one month ago, shortly after the ice bridge (left) broke. In that image, many fractures are visible but the space between them is still rather compact.

However, in the recently captured main image, these gaps have greatly widened and the icebergs can be seen breaking off and moving away from the ice shelf, indicating its high instability. The last remnants of the ice bridge can be seen on the far left edge.

Just over two weeks ago, the 500 meter wide ice bridge linking the Wilkins Ice Shelf to Charcot Island (upper left)  snapped.

The remnants of the bridge can be seen in the close-up. The bridge had been holding back icebergs from the desintegrated ice shelf. These icebergs continue to move out towards the open ocean.

The second close-up focuses on the ice shelf’s connection to Latady Island (lower left), which scientists fear could ultimately break apart as well.

In the five-day period between when these images and those from the previous article were captured, many new rifts and cracks have appeared, and the pre-existing cracks have widened. (Please click here to see the previous article).

Icebergs from Wilkins Ice Shelf Continue to Move Away from Antarctic Peninsula

Since the collapse of the ice bridge connecting the Wilkins Ice Shelf to Charcot Island (upper left) 10 days ago, icebergs from the desintegrated ice shelf appear to be moving farther away from the Antarctic Peninsula, towards the open ocean.

The remaining part of the ice shelf’s connection to Latady Island (lower left) is also thinning. Here, large cracks near the island can be seen.

According to the British Antarctic Survery, it is probable that the current reduction in ice-shelves in the region has no precedent in the last 10,000 years, and certain that this minimum has not been reached at any time in the last millennium.

The ice bridge ruptured while negotiations on a new climate deal were taking place in Bonn, Germany. At that time, Greenpeace stated that the shattering of the ice bridge connecting the Wilkins ice shelf to Antarctica was a complete contrast to progress on global action.

A Greenpeace International spokeswoman announced that “The breakup of this ice shelf is in vivid contrast to the glacial pace of the international climate negotiations, where governments are trying to avoid acting responsibly – and bickering about who’s at fault”, and called for industralised countries to commit to cutting emissions by 40% by the year 2020 and following concrete measures to support developing countries’ efforts to decarbonise.
