DCO Research Carbon Dioxide in Deep Waters: Sparkling Water or Acid?

Computer simulations suggest that when carbon dioxide dissolves in water under conditions in the upper mantle, it primarily turns into carbonic acid. The presence of carbonic acid in the mantle has…

DCO Highlights Field Report: Ol Doinyo Lengai Volcano

For the first time in 12 years, researchers have collected lava samples from Ol Doinyo Lengai in Tanzania, the only natrocarbonitite volcano in existence. They used homemade gas sensors to study its…

DCO Highlights New video featuring Alexandra Navrotsky

Navrotsky and her team at the University of California, Davis, (moving to Arizona State University) have invented an instrument to study high temperature materials, including rare earth oxides.

DCO Research Subseafloor Biofilms Grow with the Flow

To find out what kinds of microbes live in the nooks and crannies of the ocean crust, researchers dropped sterilized rocks into plugged drill holes. The biofilms that grew on the rocks were somewhat…

DCO Research Early Magma Ocean Turned Earth into a ‘Diamond Factory’

In conditions simulating early Earth’s magma ocean, iron performs an unusual chemical trick that could explain how Earth’s surface first became habitable and how the mantle accumulated so much carbon…

DCO Research Tiny Bubbles Add Up to a Big Reservoir of Abiotic Methane

Once thought to be hard to find, methane that forms in the absence of life may be incredibly widespread on Earth and elsewhere in the solar system. It exists in microscopic bubbles that form from…

DCO Highlights Deep Carbon Science at Goldschmidt 2019

The Deep Carbon Observatory was well represented at Goldschmidt 2019, which took place from 18–23 August at the Centre Convencions Internacional in Barcelona, Spain.

DCO Research Superdeep Diamonds Carry Primordial Helium

Results from the first ever analysis of helium isotopes from fluids trapped in superdeep diamonds support the existence of a reservoir of ancient helium that has existed in Earth’s interior since its…

DCO Highlights Wiki Education's Student Program

A Wikipedia writing assignment is a great opportunity for instructors to teach science communication skills on a world stage. In this kind of assignment, students create or improve Wikipedia articles…

DCO Highlights Collecting Diamonds Only a Scientist Could Love

Earlier this year, DCO researchers traveled to the Juína municipality in Brazil, an area that has been supplying ultra-deep diamonds to science for more than 20 years. They collected many of these…
