Since 2009, members of the Deep Carbon Observatory Science Network (a community of more than 1200 scientists from 55 countries) have published nearly 1500 papers in scholarly journals. In an effort to bring this enormous body of work together and share a decade of deep carbon science with both scientific and broader audiences, DCO launched a synthesis effort in late 2015. Led by Marie Edmonds (University of Cambridge, UK) and Synthesis Group 2019, DCO’s synthesis effort has produced books and special issues, resources and films, and launched new research projects that will move deep carbon science forward into the next decade. This scientific synthesis effort has succeeded thanks to the dedication of the deep carbon science community and the leadership of numerous volunteers. This page highlights the synthesis products created under the leadership of SG2019.
