Description

Excerpt from the official synopsis on Grants.gov (shortened; read the full text on 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. …
