Abstract
An underwater vibrator apparatus for generating a shear wave into the consolidated seabed has a housing, a horizontally mounted mass attached to said housing for movement along an axis substantially parallel to the surface of the earth and hydraulic apparatus for oscillating the mass along the axis. Substantially all of the vibrator housing comprises a sidewall and a bottom. The sidewalls and bottom form a wedge-shaped surface means with an angled surface of the wedge-shaped surface transverse to the movement of the mass, such that as the mass oscillates the underwater vibrator against the consolidated bottom, the vibrator will settle into the bottom. The vibrator will, however, maintain contact with the bottom even when the consolidated bottom is yieldable under vibrated weight.
