A sweep is either a contact sweep, a wire dragged through the water by one or two ships to cut the mooring wire of floating mines, or a distance sweep that mimics a ship to detonate the mines. The sweeps are dragged by minesweepers, either purpose-built military ships or converted trawlers.
Can a human set off a sea mine?
And how are sea mines different from land mines? A WWII-era sea mine could definitely explode. More than 550,000 sea mines were laid during World War II; they could be set off by contact, or by sensing the magnetic change caused by a passing ship or submarine.

Are there floating mines on the High Seas?
Floating mines can usually be spotted visually. However, contact and off-route mines are very serious problems indeed and the latter are almost as insoluble a problem as pressure mines are on the high seas. The major difficulty is that the riverine environment forces the adoption of very small craft which have correspondingly limited capability.
