Seaweed Boom is designed to serve as a barrier to prevent Sargassum, seagrass, and other seaweed from reaching beaches, shorelines, and other areas that can become problematic when overwhelmed by seaweed or other types of debris. Seaweed Boom is constructed to be deployed parallel to the shoreline, forming a line of defense to keep the Sargassum from reaching the beach. The floating barrier provided by the seaweed boom keeps the Sargassum off the beach and/or directed to a targeted shore location where it can efficiently be collection and removed. The skirt is built with a mesh fabric that allows water to flow through. This mesh fabric is a better alternative than netting that can trap sea life.
