5 February 2014

A 10-year global quest to discover the quantity, movements, origins, and forms of Earth’s deep carbon; to probe the secrets of volcanoes and diamonds, sources of gas and oil, and life’s deep limits and origins; and to report the known, unknown, and unknowable by 2019.

The DCO aims to create legacies of instruments measuring at great depths, temperatures, and pressures; networks sensingfluxes of carbon-containing gases and fluids between the depths and the surface; open access databases about deep carbon; deep carbon researchers integrating geology, physics, chemistry, and biology; insights improving energy systems; and a public more engaged with deep carbon science.

Mission

Why Carbon?

• the element of life• source of most of our energy• leading role in climate change• leading role in natural hazards (earthquakes,

volcanoes)• magic of gemstones

Why Deep Carbon?

Ignorance of• quantities (size of reservoirs)• movements (fluxes)• origins (of hydrocarbons, life, diamonds)• forms (4,000 may exist)

2008 Workshop “Deep Carbon Cycle”

Three examples of exciting work

A “big data” approach to all earthquakes & volcanic eruptions

Lessons so far

1) Archive from the outset2) Build & share instruments in a timely way3) Commit to open access4) Use a Baseline Report early (‘the Known”)5) Use unifying power of data science & management6) Start “engagement” early, identity helps attract, build

community; convenience matters7) Use milestones & risk register8) Value partnerships 9) Organize field work plans far in advance10) Attend to synthesis (and modeling) in a timely way11) Hold dedicated activities for early career people12) Value Sloan’s internal & external review & advisory

processes13) Avoid (premature) policy, maintain careful relations with

advocacy groups, industries

• Released 5 March 2013• Open Access• 20 chapters• 700 pages• 51 co-authors from 11
