Second DCO International Science Meeting, Munich, Germany, 26-28 March 2015

More than 175 scientists from 18 countries participated in the Second Deep Carbon Observatory International Science Meeting, which was held at the Deutsches Museum in Munich, Germany from 26-28 March 2015.

More than 175 scientists from 18 countries participated in the Second Deep Carbon Observatory International Science Meeting, which was held at the Deutsches Museum in Munich, Germany from 26-28 March 2015.

The scientific program featured 47 plenary oral presentations and 119 poster presentations that addressed all aspects of DCO's diverse research portfolio. From the nature of the deep biosphere in Earth's crust, to the cycling of carbon into and out of the mantle, to the role of carbon in the core, the plenary program spanned all four DCO research communities: Deep Life, Deep Energy, Reservoirs and Fluxes, and Extreme Physics and Chemistry. A group of presentations highlighted several of DCO’s innovative and advanced instrumentation projects. Another group of presentations addressed DCO’s global suite of field studies.

The meeting’s scientific program was complemented by an opening icebreaker reception, community dinners, receptions accompanying the poster sessions, and a dinner for all conference attendees on the final evening of the meeting. This combination of events resulted in a collegial and intellectual experience, facilitating new, cross-disciplinary collaborations, and nurturing the growing DCO Science Network.
