Core Samplers

Core samplers are used when an undisturbed sample of sediment is required. They are suitable especially for clay, silt, or sand bottom and are used more widely in lakes than in streams. Hand corers designed for manual operation can be used in shallow water as much as several meters in depth. Deeper water requires devices such as the Wildco® K-B type or Ballchek corer which depend on gravity to drive them into the sediment. The AMS sort sediment corer and the Ogeechee sand pounder both work with a drop hammer to drive the sampler into the river or lake bottom. All corers have been designed to retain the sample as the instrument is withdrawn from the sediment and returned to the surface. The parts for the Wildco® K-B type and Ballchek corers are interchangeable allowing for maximum flexibility. Depending on the study objectives, sections of the core may be retained in the tube. Intact cores are best preserved by freezing, but the sample can be sieved, labeled, and preserved.
