DCO Research Complicated Carbon Chemistry in Magma Ocean

Computer simulations of the magma ocean on early Earth suggest that the carbon chemistry was surprisingly complex at high pressure. Iron likely sequestered much of the carbon into the metallic core…

DCO Research Introducing Hydrothermarchaeota

Researchers used cutting-edge molecular methods to describe a group of subseafloor microbes that thrive in the hot, oxygen-free fluids flowing through Earth’s crust.

2019 Year of Carbon
DCO Highlights 2019 Designated as the "Year of Carbon"

The Geological Society of London has designated 2019 as the “Year of Carbon.” Throughout the year, the Society will explore the geoscience of carbon through research conferences, public lectures,…

2018 DCO Year in Review
DCO Highlights Deep Carbon Observatory 2018

Highlights of DCO activities in 2018 are captured in a presentation prepared by the DCO Secretariat.

Turrialba volcano in Costa Rica
DCO Research Copper Trapped Inside Volcanic Crystals

Using rocks erupted from San Cristóbal volcano, researchers analyzed the contents of shrinkage bubbles inside melt inclusions, which form within olivine crystals as they cool inside rising volcanic…

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…
