Abstract : The data recorded at the four-seismograph array at Station Inge Lehmann, Greenland, shows that the noise is incoherent between seismographs at periods less than 1.5 sec. For periods greater than 1.5 sec, coherences are high. The velocities of the waves on the noise have not been determined. The detection capability of the site is discussed. A 17-element array is recommended if the array is to be expanded. (Author)
