DataONE
Data Observation Network for Earth (ONE) is a community-driven effort to provide open and secure access to environmental data from multiple data centers, networks, and organizations from across the world, called member nodes. The data it preserves represent many disciplines, scales, and nations, and are available to scientists, decision-makers, educators, and the public for free.
DataONE is a collaboration between NCEAS, the University of New Mexico, the Oak Ridge National Laboratory, the California Digital Library, NESCent, and a number of other organizations.
