The Damping of the Chandler Wobble and the Pole Tidenal and theoretical limitations the actual damping rate is uncertain even now; a decay time of 45–70 years or more seems probable. The two most likely candidates for dissipating wobble energy are mantle anelasticity and a dynamic response of the oceans to wobble. Because of the frequency dependence

In contrast, comparisons between geodetic and meteorological estimates of the excitation of the polar motion are as yet not as satisfactory, indicating the presence of challenging “Vinsolved problems.” The presence of rapid high frequency fluctuations in t
