Video records, collected from 10 m above the water surface,typically showed less than 1-m horizontal displacement (often oblique to wave normal) owing to the passage ofindividual bores or breaking waves. A shoreward mass flux is associated with breaking waves and bores, but by design, bores and breaking waves pass over the drifters. Dye and water-filled balloons were released with a drifter to investigate drifter motions in breaking waves
