The Deep Carbon Observatory is approaching the end of its decade-long quest to explore and define the quantities, movement, forms, and origins of carbon in Earth. Its extensive, collaborative network of 1,000 scientists in 45 nations has made many scientific discoveries, which are increasing understanding of how Earth works. DCO’s Engagement Team is charged with telling these stories to a variety of audiences. To this end, the Team undertakes a broad range of activities, ensuring the science network flourishes and sharing its achievements both in and outside of the network. The team’s activities—everything from a robust web presence on deepcarbon.net, to an active social media presence, to sharing DCO news with the broader research communities and interested public—comprise the public face of DCO. To accurately and appropriately represent DCO, we work hand-in-hand with DCO’s leadership, its four Science Communities, Engagement Advisory Committee, Secretariat, and Data Science Teams. Our collective goal is to share timely, accurate, and interesting information to keep the community and broader audiences informed about the rapidly growing field of deep carbon science. As 2019 approaches, the Engagement Team will continue promoting DCO science, expanding its geographic and cultural boundaries. It will also work across DCO communities to develop DCO-wide materials, with an eye towards making them relevant, easily digested, and visually interesting across many digital and print platforms for wide dissemination and use. The Team is also working to improve deep carbon science content on Wikipedia and other public platforms, recording DCO’s legacy and contributions to scientific understanding.
