Carbon Degassing Through Volcanoes and Active Tectonic Regions, Spring 2019

A special theme in Geochemistry, Geophysics, Geosystems, also known as "G-Cubed,” explores advances in the field of deep carbon degassing. Edited by DCO’s Tobias Fischer (University of New Mexico, USA), Alessandro Aiuppa (Università degli studi di Palermo, Italy), and Marie Edmonds (University of Cambridge, UK), Carbon Degassing through Volcanoes and Active Tectonic Regions showcases new results from the Reservoirs and Fluxes Community’s DECADE (Deep Earth Carbon Degassing) initiative. The special issue consists of eleven articles.  

“Uniting DECADE research on volcanoes with Reservoirs and Fluxes’ work on tectonic degassing is an important aspect of our work as we refine Earth’s deep carbon budget with regards to degassing," explained co-editor Tobias Fischer.  

The theme covers carbon exchange between the Earth’s interior, the atmosphere and hydrosphere, which plays a fundamental role in planetary and atmospheric evolution. The main identified pathways of carbon release from the solid Earth are volcanoes and regions of diffuse degassing in tectonically active areas, yet the quantities, sources, variability and processes of carbon release remain poorly constrained. This special theme is on the observations, quantification and models of carbon transfer from the Earth’s crust and mantle to the surface. It includes emphasis on temporal and regional degassing variability, utilization of carbon degassing as a volcano and earthquake monitoring tool, and interdisciplinary approaches to quantify carbon emissions. The theme includes results from the Deep Carbon Observatory Deep Earth Carbon Degassing (DCO-DECADE) initiative as well as contributions from the broader community interested in carbon exchange on Earth.
