Marine debris is trash that gets into the marine environment as a result of careless handling or disposal. There are several sources of marine debris, both in the ocean and on land. Careful collection, handling, and disposal of trash, as well as attempts to reduce the amount of trash that must be disposed of, can help to reduce the marine debris problem. What is Marine Debris? Marine debris includes all objects found in the marine environment (which consists of not only the ocean, but also salt marshes, estuaries, and beaches) that do not naturally occur there. Although items such as tree branches and the bones of land animals can be considered marine debris, the term generally refers to trash (articles that have been made or used by people or discarded). The most common ©PROJECT OCEANOGRAPHY FALL 1999 MARINE DEBRIS 2 M ARINE D EBRIS categories of marine debris are plastic, glass, rubber, metal, paper, wood, and cloth. Since 1988, the Center for Marine Conservation (CMC) has organized and sponsored an annual National Beach Cleanup Campaign. Volunteers in all of the coastal states, as well as some of the states bordering the Great Lakes, collect marine debris and record their findings. CMC compiles the data and publishes the results, which have shown that significant quantities of marine debris litter U.S. coastlines. In 1991, the 12 most frequently collected marine debris items were: 1) cigarette butts, 2) plastic pieces, 3) foamed plastic pieces, 4) plastic food bags and wrappers, 5) paper pieces, 6) glass pieces, 7) plastic caps and lids, 8) metal beverage cans, 9) glass beverage bottles, 10) plastic straws, 11) plastic beverage bottles, and 12) foamed plastic cups. Although plastic is the most common type of marine debris, all debris causes problems in the marine environment. Two characteristics of trash, buoyancy and ability to be blown around affect how easily the trash can enter the marine environment....
