West Antarctic ice shelf 'breaking up from the inside out'
In a first, Ohio-based researchers have discovered an ice shelf in West Antarctica breaking up from the the 'inside out'. Using satellite-imaging, they found that a 'deep subsurface rift' which had appeared 30 km into the ice shelf in 2013 had deepened, finally breaking off a 600 square-km iceberg in 2015. This behaviour has been attributed to a warming ocean.
