Capping off the currently-planned events is FWB’s annual participation in Coastsweep - Saturday, September 16 from 10:00 am to noon on Wollaston Beach near the yacht clubs. COASTSWEEP Massachusetts was formed in 1987. COASTSWEEP participants join hundreds of thousands of other volunteers in the world’s largest volunteer effort for the ocean — Ocean Conservancy’s International Coastal Cleanup — collecting trash, fishing line and other marine debris, and recording data on what they find. This data is used to find solutions for keeping trash out of the ocean
