Seaport Particles

seaport particles include cenospheres from the ship's boilers and from the heavy trucks used to tranport the cargo once it is offloaded. Rust, wear metal, track wear, salt spray, paint flakes, tire wear, magnetite spheres, sawdust, and natural minerals are common particles in this assemblage, not in that order. The cenosphere can travel some distance from the harbor.
