Abstract

A marine vibrator with improved seal is described. The marine vibrator includes a housing and piston within the housing for generating vibratory signals. The improved seal is comprised of a two-stage seal having a first seal disposed adjacent the water interface and a second seal disposed away from the water interface, thus improving the reliability of the marine vibrator.
