More Icebergs Break Off Unstable Wilkins Ice Shelf
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.
