The 2022 Gulf of Maine HAB Science Symposium will be held March 13-14, sponsored and hosted by the Woods Hole Center for Oceans and Human Health (WHCOHH). This meeting brings together individuals with interests in HAB management and research in New England states and Canadian maritime provinces, including representatives from federal, state and local management agencies, industry groups, and academia.  The goal of this meeting is to facilitate discussion of ongoing issues, priorities, and concerns, and to share information that supports our understanding of HABs in this region, and helps to inform approaches to monitoring and management.

This meeting is supported by the Community Engagement Core of the WHCOHH through grants from the National Science Foundation (NSF OCE-1841811) and the National Institute of Environmental Health (NIEHS  P01ES028949), and the National Oceanic and Atmospheric Administration MERHAB program (NA19NOS478018).

We welcome your feedback on the meeting agenda and format!  Please send suggestions & questions to Mindy Richlen.
