Satellites spy Antarctic ‘upside-down ice canyon’

Satellites spy Antarctic ‘upside-down ice canyon’

Image caption Graphic: Some fast-thinning glaciers drain into the Amundsen Sea Scientists have identified a way in which the effects of Antarctic melting can be enhanced. Their new satellite observations of the Dotson Ice Shelf show its losses, far from being even, are actually focused on a long, narrow sector. In places, this has cut […]
