We have compared the four temporal modes of the gravity field with the six temporal modes of the magnetic field one by one. The main principal components of the core magnetic and gravity signals ...

University of Wyoming geology Professor and National Geographic Explorer Ken Sims has published a new book on the application of isotopes to understanding earth system processes. “Isotopic Constraints ...

Sophisticated analysis of tiny bubbles of ancient gas trapped in volcanic rocks, combined with new geophysical modeling, has cast new light on long-held assumptions about the deep Earth. An ...

Scientists at Yale and in Singapore have devised what may be the ultimate acid test — a comprehensive model for estimating the origins of Earth’s habitability, based in part on ocean acidity. The new ...

For over half a billion years, Earth’s magnetic field has risen and fallen in sync with oxygen levels in the atmosphere, and scientists are finally uncovering why. A NASA-led study reveals a striking ...

Geomorphology – the study of landforms and the processes that shape the Earth’s surface – integrates observations of tectonic, fluvial, glacial, aeolian, and coastal dynamics to explain landscape ...

The Mid-Atlantic Ridge in Iceland. This area is the boundary between the North American and Eurasian tectonic plates, which move apart ~ 2.5 cm/year. Subduction and the formation of continents, a ...

Our planet plunged into one of the most dramatic climate states in its long history, approximately 720–635 million years ago.

It's one of Professor of Geological Sciences Greg Hirth's favorite lines to frustrated students in the rock deformation lab: "Relax, the earth takes millions of years to do what you do in a week." ...
