Marine debris, also known as marine litter, is human-created waste that has deliberately or accidentally been released in a sea or ocean.

Deliberate disposal of wastes at sea is called ocean dumping. Naturally occurring debris, such as driftwood, are also present... https://en.wikipedia.org/wiki/Marine_debris
