In 2025, record-breaking levels of Sargassum drifted through the tropical Atlantic, heavily impacting Puerto Rico’s coastlines. In response, Governor Pedro Pierluisi declared a state of emergency on June 30, 2025. To support these efforts, the National Centers for Coastal Ocean Science (NCCOS) Harmful Algal Bloom Event Response Program is funding expanded Sargassum response activities. Led by Mar Caribe Consulting LLC in partnership with the Puerto Rico Department of Natural and Environmental Resources and the Puerto Rico Coastal Zone Management Program, the project will enhance monitoring at six coastal sites. Read the full news release to learn more about this ongoing response effort.

The U.S. National Office for Harmful Algal Blooms (HABs) at the Woods Hole Oceanographic Institution (WHOI) has released a comprehensive national science strategy outlining a decade-long roadmap aimed at enhancing our understanding, monitoring, and management of HABs. “HARRNESS 2024-2034: Harmful Algal Research and Response, A National Environmental Science Strategy” defines the magnitude, scope, and diversity of the HAB problem in United States’ marine, brackish and freshwaters; addresses knowledge gaps; strengthens coordination among agencies, stakeholders, and partners; advances the development of effective research and management solutions; and builds resilience to address the broad range of HAB impacts to vulnerable communities and ecosystems in the USA.
