Helping to Make our Beaches and Coastal Waters Safe and Clean

Marine debris, human-derived waste that has entered waterways and oceans, is of increasing concern both along New Hampshire’s coastline and in its waters. Marine debris affects marine life, recreation, fisheries and it poses health and safety hazards in our waters and beaches. N.H. Sea Grant has been addressing the problem of marine debris through outreach, education and innovative removal solutions.
