Prevention, Control, and Mitigation of Harmful Algal Blooms Program

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/).
