Prevention, Control, and Mitigation (PCMHAB)

We fund projects that identify and evaluate a range of methods, like spraying clay shown here, to eliminate or control blooms of harmful algae in ways that are safe for the environment.
Announcement: The Draft Prevention, Control, and Mitigation of Harmful Algal Bloom Programmatic Environmental Assessment is now open for public comment. The comment period ends on August 1, 2014. Please send comments to

After more than 10 years of research, HAB programs like ECOHAB and MERHAB have produced methods and strategies to improve HAB management and response. The PCMHAB program funds research to move promising HAB technologies from development, to demonstration, and finally application, culminating in wide spread use.

We also fund socioeconomic research, assessing societal impacts of HAB events at local scales, impact of HAB events on coastal economies, and the costs and benefits of mitigation strategies to aid managers in devising cost-effective management strategies.

Benefits to the public include healthier fisheries and ecosystems, fewer impacts of blooms on humans and the environment, and reductions in nuisance or harmful algae. PCMHAB is authorized as a national competitive research program within NOAA under HABHRCA.

Funding announcements for PCMHAB, as well as NCCOS's other national competitive HAB programs (ECOHAB and MERHAB), are issued on a rotating regional basis.
