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

Close date moved from August 31, 2076 to October 5, 2076, a 35-day extension (August 31 to September 30 is 30 days, plus 5 more to October 5). Applicants have more time to respond.

Why it matters:

• Teams that were short on time for narrative, budget, or partner letters now have roughly five additional weeks to finish.
• Organizations that had written off this round because of the original timeline may be able to compete.
• Applicants already near completion can use the time to strengthen the proposal, but should not assume further extensions.

Next steps:

• Update internal calendars and any internal review deadlines to match October 5.
• Check whether registrations (SAM.gov, Grants.gov) need renewing so they stay active through the new deadline and submission.
• Confirm in the official notice whether other dates, such as questions deadlines or the anticipated award date, also changed, since only the close date was flagged here.

Close Date changed from 2076-08-26 to 2076-08-31

This is an NSF unrestricted grant opportunity with no cost-sharing requirement, offering up to $110M across approximately 350 awards for science and technology research—meaning any entity type can apply without matching funds.

This update clarifies that NSF Geosciences Research accepts foundational research across three programs (AGS, EAR, OCE) and emphasizes that proposals don't need commercial viability or near-term applications to be competitive—enabling basic science focus over applied outcomes.
