noun

jetsam

JET-sum/ˈdʒetsəm/

Unwanted goods thrown away, especially overboard from a ship.

Pieces of jetsam wash ashore after the crew discards damaged cargo.

Discarded shipboard goods washed onto a quiet shore: an empty wooden cargo crate, a coil of rope, and a dented metal pail resting at the edge of a receding wave.
Etymology

An “act of throwing” referred here to throwing goods overboard to lighten a ship. The name shifted from the action to the discarded goods, and then more broadly to discarded odds and ends.
