Bringing together experts to share information and start discussions on the future of bioextraction in the Sound.

Nutrient bioextraction projects have been on-going within the Sound, and the nation, to better understand how bioextraction efforts can be used to help improve our waters. At the symposium, attendees heard from professionals in the field on how their work is bringing vital information to the forefront and helping to determine how to plan for the future of a successful seaweed bioextraction program.

The Long Island Sound Bioextraction Symposium was held on May 18-19, 2022 and was coordinated by the Long Island Sound Study, NEIWPCC, and the New York State Department of Environmental Conservation.
