Abstract This study presents geophysical data from two passive seismic measurements conducted at two different sites in Antarctica. We analyzed the signals mainly in the frequency domain through the multitaper method to extract some spectral characteristics of the signals that would have been out of reach through the usual FFT approach. The power spectral density of the signals carrie... https://www.roneverhart.com/BarConic-Drinkware-Tiki-Mug-copyright-18oz/
