British scientists discovered the 820-foot tunnels in West Antarctica
They were detected on airborne radar imaging and satellite photos
Suggest that water flows in concentrated 'rivers' beneath ice sheets
The information will be used to predict how the ice will melt
A team of British scientists has discovered tunnels that are almost as tall as the Eiffel Tower under an ice shelf in Antarctica.
Researchers from a number of UK universities and the British Antarctic Survey - a research centre based on the continent - detected the tunnels when they flew a plane over the Filchner-Ronne Ice Shelf in West Antarctica.
Radar from the plane, as well as satellite photos, revealed that ridges and cavities on the surface of the ice sheet corresponded to tunnels lying at its base.
British scientists discovered the tunnel using radar from the specially-modified plane. It revealed that ridges and cavitieson the surface of the ice corresponded to 820-foot-high tunnels hidden at the base of the sheet

The 820-foot tunnels are nearly as tall as the Eiffel Tower - which measures just over 987 feet - and more than four times as tall as Tower Bride - which comes in at 213 feet.
Researchers concluded that the placement of the tunnels means that they were most likely formed from meltwater - water released from melting ice - that flowing underneath the ice sheet, over land, and into the ocean.
