A rift has torn the Larsen C ice shelf asunder and now the outside edge of the ice is moving at an unprecedented pace. When it breaks off, it will become one of the largest icebergs ever recorded.
The crack is just eight miles away from breaking off what will likely be the second-biggest iceberg observed. The massive hunk of ice has already started to wiggle like a loose tooth. That includes ice near where the crack began, which is moving at an unprecedented speed of 33 feet per day. In the world of glacial-paced ice, that’s the equivalent of an all-out sprint…
The latest change brings the break-off date that much closer to happening, though researchers cautioned it could still be weeks before the crack breaks through completely. When it does, though, it will drastically alter one of the largest ice shelves on the Antarctic Peninsula. Scientists estimate that 10 percent of the ice shelf will break off, an area roughly as large as Delaware. That will change how the remaining ice shelf behaves, though it will take years of monitoring to see how those changes play out.
