Greenland

In 1966, US Army scientists drilled down through nearly a mile of ice in northwestern Greenland -- and pulled up a fifteen-foot-long tube of dirt from the bottom. Then this frozen sediment was lost in a freezer for decades. It was accidentally rediscovered in 2017. In 2019, University of Vermont…

Most of Greenland is covered with ice today. But a new study shows that within the last million years it melted off and became covered with green tundra, perhaps like this view of eastern Greenland, on the coast near the ocean. The research provides strong evidence that Greenland is more…

During the earth formation, some catastrophic impacts took place that would have generated enough energy to melt our planet’s interior. Be that as it may, we don’t think a lot about this distant and fiery period of Earth’s history because the tectonic process has reused practically all rocks older than…

New research led by the University of Cambridge has found rare evidence -- preserved in the chemistry of ancient rocks from Greenland -- which tells of a time when Earth was almost entirely molten. The study, published in the journal Science Advances, yields information on a important period in our…

Home News An outcrop of Greenland's Isua supracrustal belt contains the oldest known rocks on Earth. (Image credit: Hanika Rizo) Rocks collected in Greenland may hold traces of an ancient magma ocean that bubbled over much of Earth's surface soon after the planet's birth, a new study finds. Scientists gathered…

By Karina Shah Greenland’s Isua supracrustal belt Hanika Rizo Chemical signatures in 3.7-billion-year-old basalt rocks from Greenland support the long-held theory that Earth was once almost entirely molten. We know very little about what early Earth looked like – but one theory says that at several times it was almost…

The labels point out several series of layers that helped the researchers precisely date the oldest sauropodomorph fossils in North America.

CO2 Dip May Have Aided Herbivores on a 6,500-Mile Trek A new paper refines estimates of when herbivorous dinosaurs must have traversed North America on a northerly trek to reach Greenland, and points out an intriguing climatic phenomenon that may have helped them along the journey. The study, published today…
