Prevention, Control, and Mitigation of Harmful Algal Blooms Program
Last verified by NonDilute: 2026-04-29. Official notice and agency instructions control.
If you have a tested or emerging technology to control harmful algal blooms, NOAA will fund large-scale field validation with up to $1M annually for five years.

What this is
The NOAA NCCOS Competitive Research Program (PCMHAB) is seeking proposals to advance harmful algal bloom control technologies through rigorous testing and transition to operational use. Two focal areas are prioritized: (1) emerging technologies needing proof-of-concept validation, and (2) mature technologies requiring large-scale field validation or proven solutions from other domains (freshwater HABs, oil spills) adaptable to marine HABs. Up to $2.5M is available in year one to fund 3–5 projects, with awards up to $500K/year (focal area 1, 3 years) or $1M/year (focal area 2, 5 years). This is a competitive federal grant ideal for research teams, small businesses, and universities with coastal science expertise and proven technical capacity.
Who can apply
Universities, non-profits, small businesses, and research institutions are eligible; see the 'Additional Information on Eligibility' section in the full announcement for specific guidance. U.S. entities with capacity to conduct coastal field research and technology transition are prioritized.

Full description — from the agency
The purpose of this document is to advise the public that NOAA/NOS/National Centers for Coastal Ocean Science (NCCOS) Competitive Research Program (NCCOS/CRP) [formerly Center for Sponsored Coastal Ocean Research (CSCOR)/Coastal Ocean Program (COP)] is soliciting proposals for the Prevention, Control and Mitigation of Harmful Algal Bloom (PCMHAB) program. The PCMHAB program seeks to develop and transition technologies and strategies for preventing, controlling, or mitigating harmful algal blooms and their impacts. For this announcement, PCMHAB will prioritize proposals focused on the comprehensive testing of harmful algal bloom control technologies that fit one of the two following focal areas: (1) promising control technologies that are in need of further testing to prove feasibility; and (2) proven control technologies that are still in need of large-scale field testing or that are already approved related control technologies (e.g., freshwater harmful algal blooms, oil spills, etc.) that could be transferable to harmful algal blooms in the marine environment. Funding is contingent upon availability of Federal appropriations. It is anticipated that approximately $2,500,000 may be available to support the first year of three to five projects. Proposals may request up to $500,000 per year for up to 3 years (focal area 1) or up to $1,000,000 per year for up to 5 years. NCCOS/CRP may reject any PCMHAB proposals submitted with an annual budget for any year that is greater than $500,000 for focal area 1 projects or $1,000,000 for focal area 2 projects. --- An informational webinar on this solicitation will be offered on March 26, 2026 from 2 to 3 p.m. Eastern Time. Information regarding this Announcement, including the webinar and additional background information, is available on the NCCOS PCMHAB webpage (https://coastalscience.noaa.gov/science-areas/habs/pcmhab/).
