Apparatus for extracting material floating on the surface of a fluid having waves thereon is provided comprising means (20) for causing the waves to break, means (36) for directing the broken waves to induce a downward flow of surface fluid and the material thereon, means (34) for discharging the downward flow of fluid and said material a preselected distance below the surface of the fluid, and means (20, 22) for containing the discharged material. In a particular embodiment, a submerged refractive structure in the form of a dome-shaped shell (20) is provided to cause the waves to break. Guide vanes (36) direct the broken surface waves into a centrally disposed vertical standpipe (34) where the fluid and the entrained floating material flows downward and is then discharged at the bottom of the shell. The material accumulates at the upper interior portion (22) within the shell. An access opening (50) is provided through the wall of the shell to facilitate removal of the material accumulated within the shell.
