Biology Meets Subduction
On 11 February 2017, 25 researchers from six nations met in San Jose, Costa Rica for a 12-day sampling expedition across the Costa Rica volcanic arc. Members of the four Deep Carbon Observatory Science Communities conducted a scientific investigation at Costa Rican volcanic sites through the lenses of biology, chemistry, physics, and geology. This multidisciplinary view is affording researchers from different fields the unique opportunity to work side by side, sharing their insights, and asking questions to achieve a broader picture of the role of carbon in this active volcanic arc.
Investigating Western Aleutian Volcanoes
In September 2015, several Deep Carbon Observatory scientists took part in a US NSF sponsored GeoPRISMS expedition to the Aleutian Islands onboard the R/V Maritime Maid. DCO DECADE (Deep Carbon Degassing) scientists Taryn Lopez (University of Alaska Fairbanks, USA) and Tobias Fischer (University of New Mexico, USA) focused their work on the Western Aleutian volcanoes, and captured stunning video of the expedition.
Searching magmatic CO2 degassing in the Afar Rift
From 1-12 November 2017, an international group of scientists headed to Afar, Ethiopia to measure carbon dioxide degassing in this rifting area, where three tectonic plates are spreading out. The team, led by Raphael Pik and Bernard Marty of the CNRS at the University of Lorraine, France, is trying to understand the deep, magmatic origins of degassing in this tectonically active region. The expedition was supported by the Richard Lounsbery Foundation and the Deep Carbon Observatory.
Closer to Forecasting Volcanic Eruptions
On average, 40 volcanoes on land erupt into the atmosphere each month. Deep Carbon Observatory scientists are studying volcanic emissions at sites around the world, and will more than triple the number of permanent volcano gas monitoring stations from 2012-2019.

Disko Island Expedition: Snow Algae
In August 2013, the Deep Carbon Observatory and the UK Centre for Astrobiology sent an international team of researchers to Disko Island, Greenland, to assess the value of this site to deep carbon research. While there, expedition leader Claire Cousins (University of Edinburgh, UK) captured video footage of the research taking place. In this first video, Mark Fox-Powell (University of Edinburgh, UK) talks about the snow algae of Lyngsmarksbraen.
Investigating the Deep Past in Dziani Dzaha Lake
A French research team is investigating volcanic carbon's role in fueling biomass in the Dziani Dzaha crater lake located in the Comoros Archipelago, a small volcanic hotspot chain in the Indian Ocean between Madagascar and Mozambique. The alluring emerald Dziani Dzaha on Petite Terre, one of France's Mayotte islands, may prove to be a gem to Deep Carbon Observatory (DCO) scientists seeking to understand Earth's early life. It may also have implications for the existence of significant deep carbon "bioenergy factories" in Earth's history.
Deep Carbon Observatory Field Studies
As part of their 10-year mission to clarify the role of deep carbon in Earth’s past, present, and future, Deep Carbon Observatory scientists are heading to some of the most remote and scientifically valuable places on the planet. From establishing global volcanic monitoring systems to collecting sediment cores at the bottom of Earth’s expansive oceans, DCO scientists are using a vast array of techniques and technologies to find clues at the surface about carbon lying deep inside Earth.
X Ray Diffraction of Super-deep Diamonds
In this video, Fabrizio Nestola demonstrates the instrument used in new research about how large diamonds form deep in Earth's mantle.
