Marine Debris

Marine debris can be anything made by humans which ends up abandoned in the marine environment. Marine debris may be intentionally or unintentionally, directly or indirectly discarded into the marine environment. Sources include both ocean based such as cargo ships, fishing vessels, or oil platforms; and land based sources (i.e. carried from roadways to storm drains or other waterways flowing into the ocean).

NOAA Marine Debris Program

Marine debris can cause negative economic, human health and safety and ecological impacts. Floating debris can be dangerous and costly to vessels - large debris as navigational hazards, smaller pieces may become entangled in propellers or clog intake valves. Debris accumulated along shorelines decreases the aesthetics of the coastline. Marine habitats can be damaged such as by scouring or smothering from marine debris. Wildlife can become entangled in marine debris or may be mistaken for food and ingested by marine animals leading to injury or death. Marine debris also has the potential to transport non-native species.
