11th U.S. Symposium on Harmful Algae @ Hilton Albany
Oct 23 – Oct 28 all-day

The theme for the U.S. Symposium on Harmful Algae is 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 – creates an ideal setting to discuss progress in understanding algal bloom ecology and the solutions necessary to prevent and reduce HABs.

This conference is open to all registrants. Attendees will include national representatives and researchers from academia; state, federal, tribal, and municipal governments; the private sector; and watershed organizations. Registration will open in Spring 2022.

The symposium is coordinated by NEIWPCC, New York State Department of Environmental Conservation, and U.S. Geological Survey with support from the U.S. National Office for Harmful Algal Blooms at the Woods Hole Oceanographic Institution.
