[Mesocosm]

Mesocosms used in a pilot constructed wetland to establish zinc removal rates.

A mesocosm is shown on the right. It is prepared by coring the wetland, obtaining both sediment and plants (with their roots as intact as possible), draining the water out of the core, and sealing its bottom. Subsequently, the core is reinserted in its place of origin, where it is virtually indistinguishable from its surroundings (Left).
