Seismic surveying is conducted with an emission source and a multiplicity of aligned punctual receivers at the surface of the medium to be surveyed. Adjacent receivers are spaced apart a distance not greater than the maximum space frequency of the waves to be detected. The outputs of the receivers which include surface waves and organized noise are individually recorded for various positions of the receivers to form at least 100 seismic traces. A seismogram is formed from the traces and the seismogram is treated to remove space frequencies. In a variation, a multiplicity of punctual emission sources are used with a receiver.
