A modification of the Livingstone sampler, a thin—wall core sampler with stationary piston, will obtain long and undeformed cores of sediment from shallow lakes, with core diameters of 1 to 2 inches. Cores of 4—inch diameter up to 1½ m long can be taken with a piston sampler of slightly different design. The utility of both samplers is greatly extended by their use in combination with a drive frame and two lightweight chain hoists, which can provide up to 2 tons of force for driving and withdrawing the samplers.
