Under pressure from the environmental movement and fishing interests, Congress passed the Ocean Dumping Act, which would end the practice by1992.

Ocean dumping surveillance system

海上废物倾倒监测系统

Ocean dumping a long history, initially as coastal residents waste disposal; waste from fishing operations in direct discharge to the sea; large-scale solid waste disposal at sea forms.

海洋倾倒活动由来已久，最初表现为沿海居民处理生活垃圾；渔船作业产生的废弃物直接向海洋排放；大型固体废弃物的海上处理等形式。
