1. A method of conducting n seismic surveys simultaneously at substantially the same location where n is a whole number greater than two comprising:

  • simultaneously transmitting n times with n vibratory sources, n signals;

    detecting the n signals resulting from the n simultaneous transmissions of the n signals;

    varying the initial phases of said transmitted signals among n initial phases to enable the signal transmitted by each of the n vibratory sources to be separated from the n detected signals by data processing.
