Abstract: A trap for horizontal flow marine sediment, useful for collecting and sampling marine sediments where horizontal currents are intense and turbulent; the trap is comprising a first inlet opening and a second outlet opening, configured to allow the inlet and the outlet of a marine current, the path between the two openings comprising: an inlet area with a divergent section, connected to the first inlet opening; a sedimentation area with a greater section with respect to the inlet area, in order to allow gravity separation of particles present in the marine current. The trap also has an outlet area whose section converges in terms of width between the section where the outlet area is connected to the sedimentation area and to the second outlet opening.

Abstract: A trap for marine sediments, comprising on two vertical sides, opposite to each other, a first inlet opening and a second outlet opening, configured to allow the inlet and the outlet of the marine current, the trap comprising between said two openings an inlet area, whose section diverges in terms of width between said inlet opening and the end section of the inlet area; a sedimentation area having a section greater than the end section of the inlet area, configured to allow the separation by gravity of the particles present in the marine current, and an outlet area whose section converges in terms of width between the section where the outlet area is connected to the sedimentation area and the second outlet opening having the section of the inlet area converges in terms of height between the inlet opening and its own end section.
