 Scientists Quantify Global Volcanic CO2 Venting; Estimate Total Carbon on Earth
DCO Press Release Scientists Estimate Total Carbon on Earth

Scientists update estimates of Earth’s immense interior carbon reservoirs, and how much carbon Deep Earth naturally swallows and exhales.

DCO Research The PUSH for High-Pressure Microbiology

A large portion of deep-sea and subsurface organisms elude study due to the challenges posed by sampling and culturing microbes living in high-pressure environments. New technological advances and…

DCO Highlights 2019 DCO Emerging Leader Awards

The Deep Carbon Observatory is delighted to announce the 2019 recipients of its Emerging Leader Award.

DCO Research Microbes in Deccan Traps Go to Extremes

New research into subsurface life within the Deccan Traps, a vast, multi-layered 65-million-year-old lava flow in India, revealed distinct archaeal communities living within the volcanic rock and the…

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…
