A Benthic Macrophyte Community Core Sampler

ABSTRACT

We constructed a coring device for quantitative sampling of benthic submerged macrophyte beds. The device has a relatively large-diameter barrel to include both above- and below-ground biomass, a long (variable length) handle for direct control, and a simple sample retaining mechanism to maximize ease of operation and to minimize cost. The sampler is effective in sediments ranging from organic muds to sandy clays, and in water depths of up to four meters.
