Supports research into ocean chemistry and its role in global geochemical cycles, including chemical composition, transformation, and exchanges with other Earth system components.

--- ## Description This program supports fundamental research into the chemistry of the oceans and the role oceans play in global geochemical cycles. Priority areas include studies of chemical composition, speciation, and transformation; chemical exchanges between the oceans and other components of the Earth system; internal cycling in oceans, seas, and estuaries; and the use of measured chemical distributions as indicators of physical, biological, and geological processes. Proposals may address both observational and theoretical aspects of chemical oceanography. --- ## Due Dates - Full proposals due: February 17, 2026 --- ## Funding Amount - Award range: $200,000 to $2,000,000 per project - Estimated total program funding: $26,000,000 - Expected number of awards: Approximately 20 - Funding instrument: Grant - No cost-sharing or matching required --- ## Eligibility - Open to all applicants; unrestricted eligibility - Institutions of higher education, nonprofits, for-profit organizations, and other entities are eligible - International collaborations may be supported if well-justified --- ## Application Process - Proposals must be submitted via [Grants.gov](https://www.grants.gov/search-results-detail/275150) or [NSF FastLane/Research.gov](https://www.research.gov/research-portal/appmanager/base/desktop?_nfpb=true&_pageLabel=research_node_display&_nodePath=/researchGov/Service/Desktop/ResearchGov/Service/Desktop/ProposalPreparationAndSubmission.html) - All proposals must follow the current [NSF Proposal & Award Policies & Procedures Guide (PAPPG)](https://www.nsf.gov/policies/pappg/24-1) - Review the [program page](http://www.nsf.gov/funding/pgm_summ.jsp?pims_id=11698) for detailed requirements and guidance - Proposals should clearly address the program’s scientific priorities --- ## Additional Information - Awards are subject to NSF’s standard terms and conditions and the revised 2 CFR requirements effective October 1, 2024 - Recent updates to NSF research security policies apply, including research security training and reporting requirements - For more information and examples of funded projects, browse [recent awards](https://www.nsf.gov/awardsearch/advancedSearchResult?ProgEleCode=167000&BooleanElement=Any&BooleanRef=Any&ActiveAwards=true#results) --- ## External Links - [Program Description and Details](http://www.nsf.gov/funding/pgm_summ.jsp?pims_id=11698) - [NSF Program Page](https://www.nsf.gov/funding/opportunities/chemical-oceanography) - [Grants.gov Listing](https://www.grants.gov/search-results-detail/275150) - [NSF Proposal & Award Policies & Procedures Guide](https://www.nsf.gov/policies/pappg/24-1) --- ## 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 | GEO/OCE | | Rolf E.
