Scientific Research Grants & Programs (Ocean Alkalinity Enhancement) is a grant from Carbon to Sea Initiative that funds research on the effects of ocean alkalinity enhancement (OAE) on commercially and culturally important marine species. In partnership with the Prince Albert II of Monaco Foundation, the program awards two 24-month grants of $300,000 each.

Projects must be hypothesis-driven, focus on biological or ecological responses to OAE, and adhere to field best practices including open-access data and publication requirements. The application deadline was January 16, 2026. Partnerships with Indigenous communities and coastal industries are encouraged.

Request for proposals: effect of ocean alkalinity enhancement on commercially and culturally important species - Ocean Acidification a news stream provided by the Ocean Acidification International Coordination Center (OA-ICC) « Omics insights into ocean health: molecular adaptations and ecosystem resilience under climate stress Transcriptomic analysis of the hepatopancreas response to low-pH stress in kuruma shrimp (Marsupenaeus japonicus) » Request for proposals: effect of ocean alkalinity enhancement on commercially and culturally important species Published 6 November 2025 In a joint effort, the Carbon to Sea Initiative , and the Prince Albert II of Monaco Foundation (PA2F), are soliciting proposals to study the impact of ocean alkalinity enhancement (OAE) on commercially and culturally valued marine species.

The aim of this funding opportunity is to understand the potential risks and co-benefits of OAE deployment strategies in preparation for open-system field experiments. In the framework of this partnership, Carbon to Sea and PA2F intend to fund two 24-month awards of $300,000 USD. Applications are due Friday, January 16, 2026 .

Projects should investigate impacts of OAE on valued species and have relevance to societal priorities. The identification of local priorities may be included as part of the project scope and budget. Partnership with non-academic communities is encouraged but not required (e.g., Indigenous communities, community leaders, fishing and aquaculture industry).

Projects must adhere to the following requirements: Target species must have significant commercial and/or cultural value . Target species, communities, and life stages may inhabit any part of the water column in nearshore or offshore habitats. While species with commercial and cultural value is a priority, species of high ecological value, such as keystone species, may also be considered.

Experimental research must be hypothesis-driven and target biological and/or ecological responses. Hypotheses must be rooted in scientific findings and advance knowledge applicable to real-world OAE operations.

Investigations may include, but are not limited to, physiological processes, performance curves, ecological processes and interactions, biological co-benefits (i.e., mitigation of demonstrated biological or ecological harm of ocean acidification). Projects may include energetics, ecosystem modeling, or parameterization as an additional component, if relevant.

Any OAE feedstock is eligible for testing (e.g., NaOH, MgO, CaO, olivine, other particulate sources) so long as the feedstock is relevant to approaches currently under development. Experiments must prioritize investigations of changes in carbonate chemistry caused by OAE, with secondary consideration of feedstock-specific interactions (e.g., impact of trace elements, particles).

Experiment treatments must include, but do not need to be limited to, exposures applicable to real-world deployment strategies and the alkalinity changes that they are anticipated to achieve. For example, ocean alkalinity may change by a few hundred μmol kg −1 at most on a regional scale, and higher, shorter exposures may be relevant at local scales.

This includes experimental designs that test short-term exposures, long-term exposures, recovery effects, among others. Projects should align with best practices in the OAE and mCDR field.

Examples include: Aspen Institute’s Code of Conduct for mCDR Research AGU’s Ethical Framework for Climate Intervention Carbon to Sea’s OAE Data Management Protocol State of the Planet’s Guide to Best Practices in Ocean Alkalinity Enhancement Research United Nations’ Free, Prior and Informed Consent Manual National Wildlife Federation’s Informing mCDR Projects: Best Practices Guidance for Tribal and Indigenous Engagement University of Delaware’s Developing Best Practices for Community Engagement in Marine Carbon Dioxide Removal (mCDR) Research Experiments focused only on phytoplankton Open-access publication of the data, within 6 months of data collection.

Data management must follow guidelines of the OAE Guide to Best Practices ( Jiang et al. , 2023 ) and Carbon to Sea’s OAE Data Management Protocol . Open-access publication(s) of the study findings.
