Welcome to the Deep Carbon Observatory

A global community of more than 1000 scientists on a ten-year quest to understand the quantities, movements, forms, and origins of carbon inside Earth.

These archaea, Altiarchaeales, were originally found living in sulfidic springs in Germany. Scientists collected water samples from a 30m-deep borehole, however the cells they analyzed could be living at much greater depths. Each cell is surrounded by a fuzzy coat of “hami,” hair-like appendages with “grappling hooks” at the end and barb-wire-like prickles along their length. These surface structures help the cells stick to surfaces. Image courtesy of Christine Moissl-Eichinger (Medical University of Graz, Austria), colorized to enhance the forms.

DCO Highlights VIDEO: Karen Lloyd TED Talk, April 2019

Microbiologist Karen Lloyd takes us on a trip to the volcanoes and hot springs of Costa Rica, shining a light on subterranean organisms and how they could have a profound impact on life at Earth's surface....

DCO Research Archaea Are Winning In Oxic Sediments

Highly efficient archaea, called Thaumarchaea, out-survive bacteria in the energy-poor, oxygen-containing sediments beneath the deep sea. These Thaumarchaea consume bits of proteins from dead cells to build their own biomass and also to obtain energy....

DCO Highlights New Book Sings Carbon’s Praises

Just in time for the “Year of Carbon,” DCO Executive Director Robert Hazen has published a sweeping history of carbon: Symphony in C: Carbon and the Evolution of (Almost) Everything....

DCO Research Volcanic Crystals Record Quick Trip to the Surface

An analysis of crystals in volcanic rocks suggests that during Iceland’s Borgarhraun eruption, magma ascended rapidly from the base of the crust, reaching the surface in just days to weeks....
