Abstract

Regular variation in the solid runoff of Antarctic glaciers with the period of 18.6 years is revealed as a result of long-term observations. It is demonstrated that the periodicity of the solid runoff correlates with the 18.6-year periodicity of the Earth’s angular velocity variations caused by the 18.6-year cyclicity of the variability of lunisolar tides. It is revealed that the vibratory gravitational sliding of glaciers to the sea is registered due to the tidal fluctuations along with many climate processes. The iceberg runoff lags as compared with the course of the variance of tidal fluctuations of the angular velocity approximately by six years.
