DCO Research Did Halogens Start the End-Permian Extinction?

Directly following a massive and prolonged series of volcanic eruptions about 250 million years ago, the end-Permian Extinction began; the most severe die-off in Earth’s history. An analysis of rocks…

DCO Highlights Inputs and Outputs at Hikurangi Margin

DCO researchers aim to make highly accurate estimates of volatile compounds entering and escaping the subduction zone on the North Island of New Zealand, where the oceanic Hikurangi Plateau sinks…

DCO Research Amino Acids Fuel Fracking Communities

A small and interconnected microbial community lives in deep shales. The microbes persist in the salty fluid-filled cracks created by hydraulic fracturing. They survive by consuming amino acids such…

DCO Research Carbon Dioxide May Stay Solid Into Deep Mantle

Researchers showed that under the intense temperatures and pressures that exist close to the core-mantle boundary, carbon dioxide can exist as a covalently bonded, extended crystalline form called…

DCO Highlights Easy and Open Sample Registration

A new grant from the Alfred P. Sloan Foundation will support an international initiative, led by Kerstin Lehnert (Lamont-Doherty Earth Observatory, USA), to establish an international cross-…

DCO Highlights Video: Oman Drilling Project

The Oman Drilling Project is a collaborative multinational investigation of the Samail Ophiolite, the world’s largest, best-exposed, and most-studied subaerial block of oceanic crust and upper mantle.

DCO Highlights CALL FOR NOMINATIONS: 2018 DCO Emerging Leader Awards

The Deep Carbon Observatory invites all members of the DCO community to submit nominations for the 2018 DCO Emerging Leader Awards.

DCO Research Origin of Blue Diamonds Discovered

DCO researchers analyzed dozens of rare, expensive blue diamonds to find the origin of these elusive gemstones. Mineral inclusions trapped inside the diamonds reveal that the gems have a deep and…

DCO Highlights Oman Drilling Project Core Logging Starts on D/V Chikyu

On 7 July 2018, members of the Oman Drilling Project boarded the drilling vessel Chikyu in Shimizu port, Japan, to begin logging cores collected during Phase Two fieldwork, which took place from No

DCO Research Enceladus Harbors Complex Carbon Compounds

Data from the NASA-ESA Cassini-Huygens mission indicate that Saturn’s moon Enceladus has complex organic molecules floating in its global ocean. The source of these compounds is unknown, but…

DCO Research Ancient Reefs Contribute to Global Warm Spells

When the movement of tectonic plates pushes buried ancient reefs into contact with subduction zones, it liberates the carbon in the reef, which escapes through volcanoes. These interactions send…
