Abstract
A sediment sampling system that may be used for oceanographic sampling of trital and sedimentary sized particles in multiple sequences for up to a period of several months. The sampling device has the basic feature of exposing a plastic sheet of sediment collecting material for a predetermined period of time and rolling it up interleaved with a cover plastic sheet, with the sample sandwiched therebetween, for storage. The system includes a sampling bed and an elongated roller at one end of the bed for supplying the sheet of sample collecting material. At the opposite end of the sampling bed are a top elongated cover sheet supply roller and a bottom elongated storage roller. Both the sample collecting material and the cover material, with the sample sandwiched therebetween, and rolled onto the bottom storage roller for storage after each predetermined sample collection period. A honeycomb structure is positioned above the bed to prevent ocean currents from disturbing the sample. An electronic timer and mechanical actuator system are employed to perform the above described functions and may provide variable timing sequences to accommodate different environmental conditions. The syste…
