DCO Scientific Steering Committees

Printer-friendly version

DCO science is categorized into four Communities - Extreme Physics and Chemistry, Reservoirs and Fluxes, Deep Energy, and Deep Life - each guided by a theme-based Scientific Steering Committee. Although each Community pursues their own set of decadal goals and guiding questions, these Communities do not rigidly divide DCO scientists, who are encouraged to be part of multiple Communities and collaborate with colleagues across disciplinary boundaries.
