Descr: A new GSN station was recently installed near the South Pole. The QSPA station now records the lowest levels of background seismic noise above 1 Hz observed at any station in the network (below the Peterson Low Noise Model) At these low noise levels, we are seeing character in the high frequency seismic spectrum that have not been observable at any other station. While is may be due to the unique structure at the site (~10,000 ft of ice), we would like to determine the "human" component to the noise spectrum by analyzing various high frequency noise sources from the South Pole station (located 8km away). We will set out high frequency sensors around the power generation facility, the ski way (runway), and the large antenna facilities to estimate the noise spectra from each of these sources. We will then compare these to the noise observed at the QSPA station in an attempt to determine if the noise what part of the noise we see at 8km is caused by human sources and what ! is natural.
