$200,000–$2,000,000 per award; approx. $26,000,000 total program funding; ~20 awards expected

Supports research on the chemistry of oceans and their role in global geochemical cycles, including chemical composition, transformation, and exchanges with other Earth system components.

--- ## Description This opportunity supports fundamental research into the chemistry of the oceans and the role of oceans in global geochemical cycles. The program encourages studies on: - Chemical composition, speciation, and transformation within oceanic environments - Chemical exchanges between oceans and other Earth system components (atmosphere, land, sediments, biosphere) - Internal cycling of chemical elements and compounds in oceans, seas, and estuaries - Use of chemical distributions as indicators of physical, biological, and geological processes The program is open to a broad range of research topics advancing the understanding of marine chemistry and its implications for Earth’s systems. --- ## Due Dates - Full application deadline: August 17, 2026 --- ## Funding Amount - Estimated total program funding: $26,000,000 - Typical award size: $200,000 to $2,000,000 - Expected number of awards: ~20 Awards are generally for multi-year projects, subject to the NSF’s standard terms and conditions. --- ## Eligibility - Eligibility is unrestricted: open to all categories of applicants, including higher education institutions, nonprofits, for-profits, and other organizations. - There are no citizenship or institutional limitations specified. - Applicants must comply with NSF’s [Proposal & Award Policies & Procedures Guide (PAPPG)](https://www.nsf.gov/policies/pappg/24-1). --- ## Application Process - Proposals must be submitted in accordance with the requirements in the program solicitation and the current [NSF Proposal & Award Policies & Procedures Guide (PAPPG)](https://www.nsf.gov/policies/pappg/24-1). - All applications must be submitted via [Grants.gov](https://www.grants.gov/search-results-detail/275150) or NSF’s FastLane/Research.gov systems. - Review the [program description and requirements](http://www.nsf.gov/funding/pgm_summ.jsp?pims_id=11698) before preparing your application. - No cost-sharing or matching is required. --- ## Additional Information - Awards made on or after October 1, 2024, will be subject to updated NSF award conditions. - Applicants must be aware of recent research security policy updates, including training and certification requirements. - For more details, see the [NSF’s research security notice](https://www.nsf.gov/notices/important/important-notice-no-149-updates-nsf-research-security/in149). --- ## External Links - [Program page and details](https://www.nsf.gov/funding/opportunities/chemical-oceanography) - [NSF Program Description PD-98-1670](http://www.nsf.gov/funding/pgm_summ.jsp?pims_id=11698) - [Grants.gov listing and application portal](https://www.grants.gov/search-results-detail/275150) - [NSF Proposal & Award Policies & Procedures Guide (PAPPG)](https://www.nsf.gov/policies/pappg/24-1) - [Browse projects funded by this program](https://www.nsf.gov/awardsearch/search-results?ProgEleCode=167000&BooleanElement=Any&BooleanRef=Any&ActiveAwards=true#results) --- ## Contact Information | Name | Email | Phone | Organization | |---------------------|--------------------------------------|----------------|---------------| | Henrietta Edmonds | [hedmonds@nsf.gov](mailto:hedmonds@nsf.gov) | (703) 292-7427 | GEO/OCE | | Elizabeth Canuel | [ecanuel@nsf.gov](mailto:ecanuel@nsf.gov) | (703) 292-7938 | GEO/OCE | | Katsumi Matsumoto | [kmatsumo@nsf.gov](mailto:kmatsumo@nsf.gov) | (703) 292-7139 | | | Rolf E.
