Funds from this grant continue support for the Engagement Team of the Deep Carbon Observatory (DCO), which provides internal and external communications services to the international community of DCO geoscientists. Led by Sara Hickox at the University of Rhode Island, the Engagement Team provides content for the Deep Carbon Observatory website, publishes a newsletter and blog, compiles an up-to-date bibliography of DCO publications, maintains a contact database on the approximately 800 DCO researchers, oversees network-wide events, spearheads public engagement efforts, provides graphic design services for DCO researchers, and works to ensure smooth intra-DCO communication of goals, priorities, and achievements. Grant funds support the continuation of these activities for an additional two years. In addition, Hickox and the Engagement Team will provide support to the newly created Synthesis Group of the DCO, which focuses on synthesizing the diverse research accomplishments of DCO researchers in anticipation of the project’s contemplated end in 2019.
