The U.S. National Science Foundation (NSF) is offering a federal grant opportunity titled "Integrated Data Systems & Services" aimed at supporting national-scale cyberinfrastructure systems and services that enhance data-intensive and AI-driven research and education. Proposals are invited for three project categories: the development of novel integrated data systems, the transition of smaller-scale systems to national-scale operations, and planning grants for future projects. This initiative is crucial for advancing foundational data cyberinfrastructure that benefits a wide range of scientific and engineering disciplines, rather than focusing on a single domain. Interested applicants, including non-profit organizations, federal agencies, and accredited institutions of higher education, can apply for funding ranging from $500,000 to $30 million, with a total program funding of $60 million available. The submission deadline for proposals is December 4, 2025, and further details can be found in NSF Publication 25-544 or by contacting grantsgovsupport@nsf.gov for assistance.
