Deep Carbon 2019


Deep Carbon 2019: Launching the Next Decade of Deep Carbon Science is an international science conference sponsored by the Deep Carbon Observatory (DCO), with support from the Alfred P. Sloan Foundation, the Carnegie Institution for Science, and other organizations. Deep Carbon 2019 will take place 24-26 October, 2019 in Washington, DC. The conference will highlight DCO’s many scientific advances, representing the culmination of ten years of deep carbon research, exploration, and discovery. Deep Carbon 2019 will also serve to launch the future endeavors of this dynamic, interdisciplinary community.



Over the course of three days, we will share DCO’s key successes and showcase novel and forward-looking achievements in science, modeling, and instrumentation through presentations, posters, exhibits, books, films, and more. 

The meeting will explore the significant progress and remaining questions in a variety of deep carbon science topics, such as:

  • the nature and extent of carbon in Earth’s core and the effects of extreme temperatures and pressures on carbon’s interactions with other elements
  • the physical and thermodynamic pathways in the crust and mantle that control the movements of organic molecules and how organic molecules such as methane form in deep Earth
  • the nature of the whole Earth carbon cycle and how has it changed over Earth’s history
  • the mechanisms that govern microbial evolution and dispersal in the deep biosphere and the ecological principles that explain deep microbial community structure

All attendees are welcome to share their experience at the meeting on Twitter using the hashtag, #DeepCarb19.

If you arrive into Dulles Airport, there are multiple options to get into downtown DC. This is a good overview that includes prices. The Silverline Express bus is a good option if you want to use public transportation. If you fly into National (DCA) Airport, there are lots of easy options to get downtown.

Once in downtown DC, most venues are within walking distance or a short Metro or cab ride away. We will provide charter bus transportation between meeting venues. But you will need to plan your way to NAS in the morning and back to your hotel after evening events.

Please note that the Marine Corps Marathon will take place on Sunday, 27 October. There will be extensive road closures from 3:30 a.m. – 5:00 p.m. to accommodate the 30K+ runners. If you are departing DC on Sunday, please allow for extra time to travel to the airport.
