Deep sea reveals linkage between earthquake and carbon cycle

In order to understand the global carbon cycle, deep-sea exploration is essential, an international team led by geologists from Innsbruck concludes. For the first time, they succeeded in quantifying the amount of organic ...

Affordable catalyst for carbon dioxide recycling

A catalyst for carbon dioxide recycling, mineral pentlandite may also be a conceivable alternative to expensive precious metal catalysts. This is the result of a study conducted by researchers from Ruhr-Universit├Ąt Bochum ...

Forest carbon stocks have been overestimated for 50 years

Basic density is widely used to compute carbon storage by trees. A formula used to calculate basic wood density has recently been corrected. Researchers estimate that the error in the initial formula resulted in an overestimation ...

Radar satellites able to measure water stress in trees

Radar technology in space can be used to measure how 'thirsty' plants and crops are. This could play a key role in improving our understanding of how ecosystems and the water and carbon cycles interrelate. In theory, we have ...

Ocean temperature as a vital sign revealing Earth's warming

Human activities have released carbon dioxide and other greenhouse gases into the atmosphere, and the result is an accumulation of heat in the Earth's climate system, commonly referred to as "global warming." But how fast ...

Soil pores, carbon stores, and breathing microbes

Researchers at the Pacific Northwest National Laboratory (PNNL) recently studied how moisture influences soil heterotrophic respiration. That's the breathing-like process by which microbes convert dead organic carbon in the ...

Deep mantle chemistry surprise: Carbon content not uniform

Even though carbon is one of the most-abundant elements on Earth, it is actually very difficult to determine how much of it exists below the surface in Earth's interior. Analysis by Carnegie's Marion Le Voyer and Erik Hauri ...
