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

The National Science Foundation (NSF) is soliciting foundational research proposals across the full spectrum of geosciences. The GEO Core solicitation is organized into three programs—Atmospheric and Geospace Sciences (AGS), Earth Sciences (EAR), and Ocean Sciences (OCE)—and seeks intellectually ambitious projects that advance knowledge of Earth’s atmosphere, near‑Earth space environment, solid Earth processes, and ocean systems. Proposals may be single‑discipline or multidisciplinary, but must focus on basic research rather than near‑term product development. Funding is anticipated to support up to 350 awards with a total estimated budget of $110 million. The solicitation is open to any eligible entity, with no cost‑sharing required, and proposals may be submitted at any time between 08/21/2026 and 08/21/2076. • Open to universities, research institutes, nonprofit and for‑profit entities. • No specific project duration stated; typical NSF awards range 2‑4 years. • Funding mechanism: standard NSF research grant. • Expected award count: ~350 projects; average award ≈ $300 k. • Emphasis on transformative, high‑impact basic science; commercial outcomes not required.
