An Epibenthic Sledge consists of a rectangular steel frame with a mesh net (often more than one) attached to it. Towed along the ocean floor, its weight scrapes into the benthos, collecting any organisms on the surface or in the first few centimeters of sediment. It also collects the organisms in the water column just above the benthos. A video camera is often attached to the net. Epibenthic Sledges are good for collecting relatively mobile (but not fast swimming) benthic organisms, but it can cause injury to delicate organisms.
