A hidden lake beneath the Greenland ice sheet at Harder Glacier suddenly burst from deep beneath the ice. The water exploded upwards, cracked the thick ice above, and shot out across the surface. In just ten days, the lake released 23.8 billion gallons (90 million cubic meters) of water. That’s the equivalent of nine hours of Niagara Falls water pressure …

A vast blob of hot rock moving slowly beneath the Appalachian Mountains in the northeastern US is now thought to be the result of a divorce between Greenland and Canada some 80 million years ago. A study by an international team of researchers challenges the existing consensus in both geographical and chronological terms. It was previously thought the breaking up …

A hidden lake beneath the Greenland Ice Sheet unexpectedly drained more than a decade ago, fracturing the ice surface and forming a large crater — an event only recently uncovered by Earth-observing satellites. The massive ice sheet, located in a remote region of northern Greenland, harbors a subglacial lake that appears to have flooded in 2014, releasing 23.8 billion gallons …

In 2014, a lake hidden beneath the Greenland Ice Sheet suddenly began to drain. The event occurred with such force that a surge of water was sent directly upwards, splitting through the ice to create a crater almost one kilometre deep. In the 10 days that followed, 90 million cubic metres of water were released from the lake – roughly …

Roughly 124 miles (200 kilometers) beneath the Appalachian Mountains in New England lies the aptly named Northern Appalachian Anomaly (NAA), a mysterious 218-mile-wide (350-km) region of unusually hot rock. Researchers have long believed that the NAA resulted from the plate tectonic movement that broke North America off northwest Africa 180 million years ago. In a new study published Tuesday in …

Scientists have discovered a previously-undetected flood under the Greenland ice sheet that spilled out with such force that it burst through nearly 300 feet (91 meters) of solid ice. The phenomenon occurred in 2014 and caused 24 billion gallons (90 billion liters) of meltwater to punch out from a subglacial lake under the ice sheet. It is the first time …

A giant blob of abnormally hot rock beneath the Appalachian Mountains formed when Greenland separated from North America around 80 million years ago, new research suggests. Scientists previously thought that this hot zone, known as the Northern Appalachian Anomaly, was left over after North America broke away from Africa 180 million years ago, but this theory does not stand up …

Greenland’s ice-covered landscape looks like an immovable block on satellite maps. Yet the story locked beneath its center suggests a very different past, one that places future coastal cities in a tight spot. During the Pleistocene – the geologic chapter that began about 2.7 million years ago and ran through innumerable swings between cold and mild – the island’s ice waxed and …

Sled dogs have been performing a vital role for people living in the Arctic for 9,500 years. In fact, the ubiquity of these dogs across the polar region is a testament to their significance. While there are various breeds of sled dog today, one breed is not only the oldest among them, it may well be the oldest dog breed …
