The Deep Carbon Observatory ( DCO ) is a global research program designed to transform understanding of carbon's role in Earth. DCO is a community of scientists, including biologists, physicists, geoscientists and chemists, whose work crosses several traditional disciplinary lines to develop the new, integrative field of deep carbon science. To complement this research, the DCO's infrastructure includes public engagement and education, online and offline community support, innovative data management, and novel instrumentation development.
19-399: In December 2018, researchers announced that considerable amounts of life forms , including 70% of bacteria and archea on Earth , comprising up to 23 billion tonnes of carbon , live up to at least 4.8 km (3.0 mi) deep underground, including 2.5 km (1.6 mi) below the seabed, according to a ten-year Deep Carbon Observatory project. In 2007, Robert Hazen ,
38-822: A Senior Staff Scientist at the Carnegie Institution ’s Geophysical Laboratory (Washington, DC) spoke at the Century Club in New York, on the origins of life on Earth and how geophysical reactions may have played a critical role in the development of life on Earth. Jesse Ausubel , a faculty member at Rockefeller University and Program Director at the Alfred P. Sloan Foundation , was in attendance and later sought out Hazen's book, Genesis: The Scientific Quest for Life’s Origins . After two years of planning and collaboration, Hazen and colleagues officially launched
57-478: A function of their genomic and biogeochemical properties, and their interactions with deep carbon. By integrating in situ and in vitro assessments of biomolecules and cells, the Deep Life Community explores the environmental limits to the survival, metabolism and reproduction of deep life. The resulting data informs experiments and models that study the impact of deep life on the carbon cycle, and

Each chapter of Carbon in Earth synthesizes what is known about deep carbon, and also outlines unanswered questions that will guide future DCO research. The Deep Carbon Observatory encourages open access publication, and is striving to become a leader in Earth sciences in this regard. DCO funding can be used to defray
95-404: Is an entity that is living , such as plants ( flora ), animals ( fauna ), and fungi ( funga ). It is estimated that more than 99% of all species that ever existed on Earth, amounting to over five billion species, are extinct . Earth is the only celestial body known to harbor life forms. No form of extraterrestrial life has yet been discovered. Life form The following outline
114-601: Is relatively depleted in highly volatile elements compared to chondrites, though DCO's research is further examining whether large reservoirs of carbon may be hidden in the mantle and core. Members of the Reservoirs and Fluxes Community are conducting research as a part of the Deep Earth Carbon Degassing Project to make tangible advances towards quantifying the amount of carbon outgassed from the Earth's deep interior (core, mantle, crust) into
133-593: Is structured around four science communities focused on the topics of reservoirs and fluxes, deep life, deep energy, and extreme physics and chemistry. The Reservoirs and Fluxes Community explores the storage and transport of carbon in Earth's deep interior. The subduction of tectonic plates and volcanic outgassing are primary vehicles for carbon fluxes to and from deep Earth, but the processes and rates of these fluxes, as well as their variation throughout Earth's history, remain poorly understood. In addition DCO research on primitive chondritic meteorites indicates that Earth
152-689: Is to improve the understanding of the physical and chemical behavior of carbon at extreme conditions, as found in the deep interiors of Earth and other planets. Extreme Physics and chemistry research explores thermodynamics of carbon-bearing systems, chemical kinetics of chemical deep carbon processes, high-pressure biology and biophysics , physical properties of aqueous fluids , theoretical modeling for carbon and its compounds at high pressures and temperatures, and solid-fluid interactions under extreme conditions. The Extreme Physics and Chemistry Community also seeks to identify possible new carbon-bearing materials in Earth and planetary interiors, to characterize
171-533: Is to quantify the mechanisms and rates of fluid-rock interactions that produce abiotic hydrogen and organic compounds as a function of temperature, pressure, fluid and solid compositions. As a result of a series of workshops, the DCO initiated an additional Science Community to examine the physics and chemistry of carbon under extreme conditions. The overarching goal of the Extreme Physics and Chemistry Community
190-685: The DCO as a whole, using a combination of informatics methods, use case development, requirements analysis, inventories and interviews. A list of some of the scientists involved in the Deep Carbon Observatory: On 11 April 2020, the Australian Broadcasting Corporation 's Science Show broadcast a 37 minute radio documentary on the DCO. Life form The following outline is provided as an overview of and topical guide to life forms: A life form (also spelled life-form or lifeform )
209-932: The Deep Carbon Observatory (DCO) in August ;2009, with its secretariat based at the Geophysical Laboratory of the Carnegie Institution of Washington, DC. Hazen and Ausubel, along with input from over 100 scientists invited to participate in the Deep Carbon Cycle Workshop in 2008, expanded their original idea. No longer focused solely on the origin of life on Earth, the group instead clarified their position to further human understanding of Earth, carbon, that critical element, had to take center stage. The Deep Carbon Observatory's research considers

#1732793923452228-551: The costs of open access publication. Recent advances in data generation techniques lead to increasingly complex data. At the same time, science and engineering disciplines are rapidly becoming more and more data driven with the ultimate aim of better understanding and modeling the dynamics of complex systems. However complex data requires integration of information and knowledge across multiple scales and spanning traditional disciplinary boundaries. Significant advances in methods, tools and applications for data science and informatics over
