This grant provides continued support to a team led by Peter Fox at the Rensselaer Polytechnic Institute to provide computational and data management services to the Deep Carbon Observatory.  Grant funds support the continued operation and development of deepcarbon.net, which is used to manage the project as a whole, coordinate member activities, and disseminate results both within the DCO and with the wider public.  In addition, the RPI team maintains a state-of-the-art computing cluster used to store and analyze data collected by DCO scientists and to run complicated and data-rich model simulations.  Grant funds provide continued support for these activities as well as additional work designed to lay the groundwork for a “deep carbon virtual observatory” that would exist as a continuing legacy after the DCO has completed its decadal research goals.
