Marine Debris Trawls
Only debris of a certain size is further analyzed and plastic separated from organic material. After analysis, we found that 16.8 mg of plastic were collected in the Annisquam River and 27.3 mg were collected in the Ipswich Bay. We also analyzed the number of pieces found at each location. We found that there were 16 pieces of micro plastic collected from the Annisquam River, and 10 from the Ipswich Bay.
