Singing water reveals itself

With a rapidly growing world population, clean drinking water has become a scarce resource. Using new technology that traces sound signals, Danish scientists hope to find groundwater in densely populated areas.

Prosperous Vikings whitewashed their walls

Archaeologists have found Denmark’s oldest lime kiln near a large Viking hall at a Viking settlement on the Danish island of Zealand.

Helicopter technology to solve Indian water shortage

Danish scientists have developed a special technology which uses a helicopter to locate groundwater. The technique is currently being used to search for clean drinking water in India.

Oxygenated Earth much older than we thought

The discovery of the world’s oldest soil suggests that Earth’s atmosphere contained oxygen as early as three billion years ago. That’s 700 million years earlier than previously thought.

Greenland icebergs may have triggered the Younger Dryas

Just as the last Ice Age was drawing to a close, Greenland icebergs changed the temperature in the Atlantic and triggered a 1,000-year-long extension of the Ice Age.

Early Earth was pounded into pieces

Scientists have found evidence of a previously unknown meteor bombardment of Earth some 4.3 to 4.1 billion years ago.

Researchers have great power in continental shelf battle

Geologists and other scientists have great power when limits are set for the continental shelf. Perhaps too much?

Historic shipwrecks could be preserved in the Antarctic

Shipworms − molluscs that bore into wood − shun Antarctic waters. This suggests that sunken ships from polar exploration history might be found in near pristine shape.

On the road with a geology app

“Are we there yet?” The road trip is wearing out the family. How about downloading the app GeoTreat and learning about our country’s oldest history?

Blowing a slope into place

Research scientists have developed a new method for stabilising areas with difficult soil mechanics.
