Marine Debris in Our Backyard

(Airdate: September 30, 2020) Marine debris are often a threat to safe boating and water quality in our region. Most obviously, marine debris can be a major navigational hazard for boaters. Less obvious, but just as harmful is the smaller debris that can and do make their way into the seafood we eat. Andrew Mason is the Pacific Northwest Regional Coordinator and Pacific Region team lead for NOAA’s Marine Debris Program and shares what types of debris gathers in the Pacific Northwest and how boaters and beach goers alike can all help reduce the debris on our beaches and in our water.
