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 ...

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 ...

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 ...

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 ...

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 ...

Bowdoin's EOS faculty are geologists, mineralogists, oceanographers, paleoceanographers, biogeochemists, and hydrologists. They're creative thinkers and stimulating mentors. The department's faculty ...

Parts of ancient Earth may have formed continents and recycled crust through subduction far earlier than previously thought. New research led by scientists at the University of Wisconsin–Madison has ...

Geologists from the University of Hong Kong (HKU) have made a breakthrough in understanding how Earth's early continents formed during the Archean time, more than 2.5 billion years ago. Their findings ...

Scientists have traced the origins of complex life to the breakup of the supercontinent Nuna 1.5 billion years ago. This tectonic shift reduced volcanic carbon emissions, expanded shallow seas, and ...
