Geosciences Core Research: Atmospheric, Geospace, Earth and Ocean Sciences (GEO Core)

The Geosciences Core Research (GEO Core) program solicitation (NSF 26-516) consolidates foundational research funding opportunities across three core divisions: Atmospheric and Geospace Sciences (AGS), Earth Sciences (EAR), and Ocean Sciences (OCE). Administered by the U.S. National Science Foundation, the program supports basic scientific inquiries that advance knowledge of Earth's atmosphere, space weather, solid Earth dynamics, ocean ecosystems, and surface processes. NSF encourages intellectually ambitious, transformative research that challenges existing paradigms, establishes new analytical methods, or builds open community datasets. The solicitation emphasizes opportunities for early-career investigators and supports the application of emerging technologies, such as artificial intelligence, advanced computation, and automation, to reveal complex scientific patterns and unlock new observational capabilities. Funding is awarded through standard grants, continuing grants, or cooperative agreements, with request durations reaching up to five years. Proposals are accepted at any time without fixed annual deadlines, allowing researchers flexibility to submit high-impact proposals via Research.gov or Grants.gov in accordance with standard NSF merit review criteria.
