Ways of improving technologies for monitoring test ban treaties are being examined. One aspect of those studies is investigating ways of maximizing the seismic signal-to-noise ratio (SNR) from seismic treaty monitoring stations. To maximize SNR, the highest quality seismometers, data acquisition and data analysis capability must be obtained. The stations must also be located at sites with low seismic noise and/or boreholes to reduce seismic noise. This paper presents the data and results obtained in measuring seismic noise as a function of depth in the Oklahoma borehole with a large nearby surface-noise source. 7 refs., 10 figs.
