Plastic Tides Science- Trawl Design
Plastic Tides is actively involved in sampling microbeads in the water. On our first expedition in Bermuda, we used a trawl designed by the Plastic Ocean Project that is dragged behind a boat to sample the floating microbeads. As we used the trawl behind our man-powered paddle boards, we found it to be quite challenging.
We now have a new design, using PVC pipes, net, rope, bolts and rods. Our design is such that the front of the pontoons rises above the water to facilitate the drag.
