| Abstract | Water level data from a shallow monitor well in the Rotorua geothermal field in New Zealand is used to compare signal processing techniques, namely discrete Fourier transform and wavelet analyses. Characteristic pressure fluctuations are identified over a wide range of frequencies indicative of influences that include tides due to celestial bodies. The techniques used for data analysis provide complimentary information on characteristic fluctuations. |
