The Ocean Carbon Data System (OCADS) is a data management project located within the NOAA National Centers for Environmental Information (NCEI) in Silver Spring, Maryland. It contains all the CDIAC-Oceans data and serves all functions of the former CDIAC-oceans including dissemination of all newly acquired ocean carbon data. OCADS was established in February 2017. OCADS is responsible for hosting and providing access for ocean carbon data collected from around the world, as previously performed by the Oceans component of the Carbon Dioxide Information Analysis Center (CDIAC-Oceans) at the Oak Ridge National Laboratory (ORNL). We aim to make OCADS a customer-centric data management entity and try to listen to the community to provide stellar customer support as was done at CDIAC. We value the importance of putting all ocean carbon data into one repository and welcome data submissions from around the world.
