| Definitionskos:definition | The Mackereth corer (Mackereth, 1958; Smith, 1959) is a pneumatic device that consists of a cylindrical aluminum chamber ~1.2m long and 0.5m in diameter. The apparatus is lowered to the lake floor on a rope, and air hoses connect the chamber to the vessel at the water surface. Compressed air is used to pump the water out of the chamber and then to force the inner core barrel downward through the chamber and into the sediment. The method can recover single-drive moderate (up to 12 m) cores from lakes of diverse depths. Mackereth cores can be deployed on virtually any small craft and can be used in water depths up to 100 metres. |
