Earth nutation influence on the temperature regime of the Barents Sea

A general system theory of the influence of the Earth's nutation on the Barents Sea temperature is presented. According to this theory, the Earth's axis behaves dynamically as a forced oscillator on a non-linear sea system that modulates a set of harmonic and subharmonic low frequency temperature cycles. A spectrum analysis of the Kola meridian time series indicates a correlation between the temperature series and the Earth nutation cycle of 18.6 years, 18.6/3=6.2 years and 18.6*3=55.8 years. The 55.8 years cycle seems to follow a moving average in the temperature series. If this theory is confirmed by further oceanographic measurements, it will open new perspectives in the forecasting of future temperature, ecological, and biological changes in the Barents Sea.
