About this opportunity
The National Science Foundation is soliciting applications for foundational geosciences research grants under the Geosciences Core Research solicitation (26-516), covering its Atmospheric and Geospace Sciences, Earth Sciences, and Ocean Sciences programs, with a listed due date of October 27, 2076. The program-level record lists October 5, 2076 for solicitation 26-516, so the two dates conflict and should be verified against the solicitation. Applicant types are unrestricted, and the funding instrument is a grant under CFDA 47.050, Geosciences, which supports basic research in the atmospheric, earth, and ocean sciences. Eligible projects advance knowledge of Earth's atmosphere and near-Earth space, solid Earth and surface processes, and all fields of ocean science, and may be single-discipline or multidisciplinary. NSF is particularly interested in intellectually ambitious, potentially transformative foundational research, and proposals need not promise a near-term product, deployment, or commercial outcome.
Submissions go through Grants.gov under the NSF 24-006 application guide, except collaborative applications, letters of intent, planning applications, pre-applications, and SBIR/STTR applications, which must be submitted through Research.gov. Grants.gov submissions pass through three validation steps before transfer, and NSF recommends submitting at least five business days before the deadline. Page limits are 15 pages for the project narrative, 5 pages for the budget justification, 2 pages for the data management plan, and 1 page for the mentoring plan. All principal investigators, co-principal investigators, and authorized representatives must hold active NSF accounts with NSF IDs.
Program-level records show Geosciences awards falling from 1,187 in 2023 and 1,154 in 2024 to 852 in 2025 and 611 in 2026. Project Grants make up 97 percent of the program's portfolio, with Cooperative Agreements making up the remaining 3 percent. The program record also lists Science and Technology Centers: Integrative Partnerships (22-521, posted October 8, 2026), a cooperative agreement opportunity targeting faculty at institutions with doctoral research programs.
Synopsis
The NSF Geosciences Research solicitation supports foundational research projects that advance the frontiers of knowledge across all areas of the geosciences. This solicitation calls for proposals in three programs:
-
Atmospheric and Geospace Sciences (AGS) Program;
-
Earth Sciences (EAR) Program; and
-
Ocean Sciences (OCE) Program.
These programs support projects that expand the frontiers of knowledge in science and technology. The programs encourage projects that advance research on Earth's atmosphere and the near-Earth space environment; solid Earth sciences and Earth surface processes; and all fields of ocean science. Projects may focus on foundational research in a specific domain or cover multiple disciplines. NSF is particularly interested in intellectually ambitious and potentially transformative foundational research. Proposals need not promise a near-term product, deployment, or commercial outcome, nor need they address later-stage development to be competitive.
