DCO Research Mars-Sized Body Delivered Earth’s Carbon

Researchers propose that a planetary body the size of Mars crashed into early Earth, simultaneously delivering a mix of volatile elements necessary for life and creating the Moon. The hypothesis is…

DCO Research A Step Toward Modeling Subsurface Carbonatites

Using high-temperature and high-pressure experiments, researchers have determined the conditions causing calcium carbonate to take the form of calcite, aragonite, or a liquid. This represents a major…

DCO Highlights Goldschmidt 2019: Sessions of Special Interest to DCO

The 29th Goldschmidt Conference will take place at the Center Convencions Internacional Barcelona (CCIB) in Barcelona, Spain, from 18-23 August 2019.

DCO Research Clumped Isotopologues Reveal Methane’s Origins

New tools that detect heavier forms of methane with “clumped isotopologues” can indicate a gas sample’s source and the temperature when it formed. More studies, however, will be needed to tease apart…

DCO Highlights DCO at the 2018 AGU Fall Meeting

More than 28,000 scientists gathered in the US capital for the 2018 AGU Fall Meeting. As in past years, deep carbon science featured prominently throughout the conference, with DCO researchers…

DCO Research First Study of Deccan Traps Microbes

For the first time, scientists have drilled deep into the Deccan Traps, a giant, 65-million-year-old lava flow in Western India, and the 2.5 billion-year-old rock beneath. DCO scientists from Indian…

DCO Research The Growth of Seafloor Carbonates in Deep Time

EarthByte researchers combined their model of plate tectonics with records of carbonate layers logged from cores collected during scientific ocean drilling expeditions. Together, these resources…

DCO Research Baltic Microbes Have a Taste for Alcohol

In the carbon-rich sediments of the Baltic Sea, microbes use a variety of strategies to make a living from different types of organic material that have settled there, including making and consuming…

When Water Meets Rock
DCO Research The First Steps When Water Meets Rock

A new study uses computer simulations and spectroscopic techniques to look at how water molecules interact with the mantle mineral olivine.

DCO Research New Estimate of Microbes Beneath the Continents

Researchers compiled hundreds of studies of the types and numbers of microbes living in the terrestrial subsurface and carefully scaled the results to come up with estimates of the total number and…

DCO Press Release Life in Deep Earth Totals 15 to 23 Billion Tonnes of Carbon

Barely living "zombie" bacteria and other forms of life constitute an immense amount of carbon deep within Earth's subsurface—245 to 385 times greater than the carbon mass of all humans on the…
