Artificial Substrate Basket

Artificial Substrate Basket

The Artificial Substrate Basket is made of one inch square, 14 gage galvanized wire with a PVC coating. The cylindrical basket measures 6 1/2" in diameter and 11" in length. One end is hinged and tied with a nylon releasable tie. The other end is permanently fastened to the cylinder. The rocks used to fill a series of samplers should be of the same general size, shape, and composition and should be cleaned by scrubbing with a brush before use.

Angular limestone commonly is used in basket samplers, although spheres of porcelain or concrete provide a more uniform substrate. Coniferous tree bark has been used as a lightweight substitute for rocks.

If possible, suspend three samplers at a depth of 0.3 m below the surface for experimentally determined exposure period or for 4 to 5 weeks. In environments of variable depth, suspend the samplers from a float.
