Stationary temperature cycles in the Barents sea. The cause of causes

This paper is based on the data series from PINROE institute in Murmansk where the temperature in the Barents Sea is measured since 1900. It presents a hypothesis that the 18.6 years cycle of the earth nutation is modulating stationary low frequency temperature cycles in the Barets Sea. A spectre analysis of data series has identified cycles of 18.6/3=6.3 years, 18.6 years and 3*18.6=55.8 years temperature cycles. The 55.8 years cycle is correlated to the mean temperature in the data series and has a maximum in 1995-97. If his hypothesis is confirmed by oceanographic measurements, it means the Barents Sea will be cooled down for a new period of 55 years. This hypothesis may open up for a new perspective on climate and fishery forecasting.
