The maximum entropy method was used to perform a spectral analysis of the time series of the geomagnetic field on the basis of data from the global network of magnetic observatories. Amplitudes, phases, and polarization parameters were determined for the 60-year variations, and the global distribution of these variations was established. Sharp amplitude differences were found in various regions of the globe: maximum amplitudes were obtained at American observatories, intermediate amplitudes at European observatories, and anomalously low amplitudes in the Pacific Ocean. This nonuniform amplitude distribution may be associated with features of the lower mantle: hot points, bumps, and a nonuniform distribution of electrical conductivity.
