Description (from the official listing)

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.
