Researchers have discovered a previously unrecorded flood beneath the Greenland ice sheet that erupted with such force that it broke through nearly 300 feet (91 meters) of solid ice.
The event occurred in 2014 and resulted in the release of 24 billion gallons (90 billion liters) of meltwater from a subglacial lake located beneath the ice sheet, the first such event recorded in the country.
By analysing this unexpected cascade, scientists say they can gain important insights into the melting of ice in the area and its devastating impact on the rest of the Greenland Shelf. The findings were published Wednesday (July 30) in the journal Nature Geoscience.
