definition A core tube is attached to a source of mechanical vibration (the power head) and lowered into sediment. The vibrations provide energy for rearranging the particles within the sediment in such a way that the core tube penetrates under the static weight of the vibracoring apparatus. Samples include stiff and stony clays, soft rock and sands, and saturated sediments which can not be sampled using gravity or piston corers. Also know as VIBRA. more like this
