ABSTRACT:
The present invention provides marine vibroseis methods and apparatus that operate in an acquisition time frame significantly shorter than current marine vibroseis acquisition methods and comparable to marine airgun seismic source acquisition, while providing data seismic energy comparable or superior to marine airgun seismic sources, by apportioning a desired vibroseis bandwidth signal over a plurality or multiplicity of vibroseis projectors (sources).
