A new special theme in Geochemistry, Geophysics, Geosystems, also known as "G-Cubed,” will explore 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), the theme is part of the Reservoirs and Fluxes Community’s synthesis activities, and is designed to showcase new results from the DECADE (Deep Earth Carbon Degassing) initiative. All members of the DCO Science Community are invited to submit articles. The submission period will run through 2018.
“We’re looking forward to bringing together a whole issue focused on deep carbon degassing,” said co-editor Tobias Fischer. “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.”
The theme is described, as follows:
Carbon exchange between the Earth’s interior, the atmosphere and hydrosphere 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.
