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.

Past winners and funding trends for this program
NSF 26-516 folds Atmospheric and Geospace Sciences, Earth Sciences and Ocean Sciences into a single GEO Core solicitation: $110 million, 200 to 350 awards, proposals accepted anytime. Geosciences piloted no-deadline review nine years ago and knows what it does to submission volume. Here is the per-award math, the ship-time and permitting traps, and the two-year data-archive clock that now governs every award.
Read articleNSF 26-520 consolidates 14 mathematical sciences programs into $200 million and 400 to 600 awards with no per-PI cap and no deadline. Folded into it are Research Training Groups and Focused Research Groups — department-scale, cohort-building competitions that ran on a fixed annual date. Here is why removing that date is a different kind of change for training grants than for single-investigator grants, and what math departments should do before the fall.
Read articleNSF 26-522 consolidates AAG, ATI and MSIP into a single astronomical sciences solicitation with $100 million and about 140 awards. Accomplishment-based renewals will be returned without review, voluntary cost sharing is prohibited, and routine instrument upgrades are explicitly deprioritized. The new Innovations track — one to three awards a year — is where facility operations and community observing time now live.
