Funds from this grant support the Rensselaer Polytechnic Institute (RPI) in its efforts to provide data science support to the Deep Carbon Observatory (DCO). The RPI team will establish a Deep Carbon Virtual Observatory for community data holdings; provide robust data infrastructure for DCO instrumentation, secretariat, and engagement activities; enable scientific discovery via visualization and analysis; and advance educational aspects of data science among all DCO participants. Planned tasks range from creating tools to capture streams of data from sensors to storing simulation results to creating a DCO-wide bibliographic infrastructure. To maximize the value of the funded activities, the RPI team will look beyond the specific needs of DCO researchers to the larger scientific community and will work closely with the U.S. Geological Survey, National Science Foundation, and counterpart agencies around the world to guide global earth science data infrastructure developments.
