FIELD: physics.SUBSTANCE: disclosed is a method for marine seismic survey using one or more marine seismic vibrators. The vibrator sweep function is based on a quality requirement, which may be a final image quality requirement or an environmental requirement. The sweep function may be nonlinear and the energy spectrum may not match the energy spectrum of an airgun.EFFECT: high accuracy and reliability of survey data.24 cl, 7 dwg |
