| Epibenthic dredge | Mining | A bottom sampler consisting of a pair of sheet-metal skis attached to a light framework for a silk or nylon net. Removable rakers in front of the net stir up the bottom as the dredge advances, permitting the net to capture the benthic fauna and flora contained in the sediment. A bottom-walking wheel connected to a small counter indicates the distance over the bottom the device travels during a haul. (references) | |
