Radar surveys have previously mapped Greenland’s bedrock buried underneath a few thousand meters of ice. Mathematical models were used to fill in the gaps in survey data and infer bedrock depths. However, the reviews uncovered the long valley, which was segmented, preventing water from flowing freely through it.  Be that…

A team of scientists from Lamont-Doherty Earth Observatory at Columbia University has discovered paleolake basin situated beneath the ice sheet in northwest Greenland; geomorphological analysis and hydrological modeling indicate that the basin once hosted a lake with a surface area of up to 7,100 km2 and a volume of up…

A new genus and species of mammaliaform that lived during the Triassic period has been identified from a partial jaw with teeth found on the eastern coast of Greenland. It represents the earliest known example of a dentary bone with double molariform roots and a crown with two rows of…

The vast Greenland ice sheet is melting at some of its fastest rates in the past 12,000 years. And it could quadruple over the next 80 years if greenhouse gas emissions don’t decline dramatically in the coming decades. Research published yesterday in the journal Nature warns that the ice sheet’s future losses depend…
