The core work of the Deep Carbon Observatory’s engagement team, headquartered at the University of Rhode Island (URI), consists of community building and management. The team writes the DCO’s newsletter, maintains a contact database of DCO-affiliated scientists, produces the DCO bibliography, handles educational and outreach partnerships with entities such as National Geographic and the Smithsonian, updates articles about the DCO and deep carbon science in Wikipedia, and conducts all media relations. As the DCO moves toward its planned conclusion in 2019, the engagement team will have additional responsibilities associated with the synthesis of DCO research and the effective communication of its import to the wider scientific community and the public. This grant continues operational support for the DCO’s engagement team for 21 months.
