A marine vibrator has a hollow body formed of one shell or of two opposed shells defining an inner space therein with vibrator apparatus within the hollow body. At least one shell has a curved shape, and the shell can have a streamlined shape with relatively low hydrodynamic drag. Certain embodiments include one or more exterior control members to facilitate positioning of the vibrator in water. Other than their mating ends, when two shells are used the two shells may be different in shape and volume or they may be identical. In preferred two-shell embodiments, there is a flexible seal between and connecting the two opposed shells. In certain aspects the inner space is filled with gas. A vibrator apparatus in one aspect applies equal and opposite forces to the shells of a two-shell vibrator or to opposed sides of a single shell vibrator.
