The symposium theme was “Science to Support Solutions from Shore to Shore.” From freshwater to marine systems, the prevalence of harmful algal blooms (HABs) is a national environmental challenge, and solutions are needed. Celebrating this event in New York – the only state with Great Lake shorelines, marine coasts, and the diverse range of ecosystems between these extremes – created an ideal setting to discuss progress in understanding algal bloom ecology and the solutions necessary to prevent and reduce HABs.

Final Symposium Program & Agenda

The conference was open to all registrants. Attendees included national representatives and researchers from academia; state, federal, tribal, and municipal governments; the private sector; and watershed organizations.
