DataONE is a network of interoperable data repositories facilitating data sharing, data discovery, and open science. Originally supported by $21.2 million in funding from the US National Science Foundation as one of the initial DataNet programs in 2009, funding was renewed in 2014 through 2020 with an additional $15 million. DataONE helps preserve, access, use, and reuse of multi-discipline scientific data through the construction of primary cyberinfrastructure and an education and outreach program. DataONE provides scientific data archiving for ecological and environmental data produced by scientists. DataONE's goal is to preserve and provide access to multi-scale, multi-discipline, and multi-national data. Users include scientists, ecosystem managers, policy makers, students, educators, librarians, and the public. DataONE links together existing cyberinfrastructure to provide a distributed framework, management, and technologies that enable long-term preservation of multi-scale, multi-discipline, and multi-national observational data. The distributed framework is composed of Coordinating Nodes located at the Oak Ridge Campus at Tennessee, University of California Santa Barbara, and University of New Mexico, and member nodes. DataONE also provides resources including tools for accessing and using it. Coordinating nodes The three coordinating nodes provide network-wide services to member nodes. They are geographically replicated, with mirrored content and full copies of science metadata. William Michener of the University of New Mexico (UNM) directed the project, and UNM is one of the coordinating nodes. Coordinating nodes are UNM, Oak Ridge Campus (partnership of Oak Ridge National Laboratory (ORNL) and University of Tennessee), and the University of California, Santa Barbara. Member nodes Member nodes consist of Earth observing institutions, projects, and networks. They provide resources for their own data and replicated data, and focus on serving their specific constituencies. These member nodes are geographically distributed and include: Cornell Lab of Ornithology eBird Dryad Earth Data Analysis Center (EDAC) Environmental Data for the Oak Ridge Area (EDORA) Ecological Society of America (ESA) Data Registry Europe Long-Term Ecosystem Research Network (LTER Europe) Global Lake Ecological Observatory Network (GLEON) Gulf of Alaska Data Portal International Arctic Research Center (IARC) Data Archive Knowledge Network for Biocomplexity Long Term Ecological Research Network (LTER) Merritt Repository Minnesota Population Center (MPC) Montana IoE Data Repository Nevada Research Data Center New Mexico Experimental Program to Stimulate Competitive Research (NM EPSCoR) NOAA National Centers for Environmental Information (NCEI) Oceanographic Data Archive ONEShare Repository ORNL Distributed Active Archive Center Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO) Program for Research on Biodiversity (PPPBio)
