Final Design

    The final design is built off an existing sediment sampler for use on a kayak. The solution is comprised of two major aspects: the sampler and its attachments, and a supporting frame that is used to expedite removal of the sample once collected (see Figure 4).

     The first aspect is the sediment sampler with attached stainless steel rod attachment and hardstop. The purpose of the rod attachment is to connect a separate extendable 1.2-2.7m (4-9 ft) pole. The hardstop, a small plate to increase surface area, is to stop the sampler at a predetermined depth and allow the user to know when the sediment sampler has reached 12.7 cm (5 in) inches of penetration, which is required to obtain a sufficient seal at the bottom of the tube. This portion of the design is dropped into the water for sample collection. Quick release pins through the sampler handle and the telescoping rod allow the sampler to be easily removed from the pole and give the user more ease of handling. A trigger mechanism(shown in Figure 3), involving a latch and release cord, is included on the pole to allow the operator to seal the sampler tube at the desired time. This trigger holds a wire leading from the cap of the sampler tube which, once released, seals the upper and lower ends of the tube.
