I’m presenting the Doctoral thesis written by Harald Yndestad for his degree as Doctor of Philosophy at the Norwegian University of Science and Technology. This work is highly relevant to our investigation of the effect of Lunar cycles on climatic variation.
The Lunar nodal cycle influence on the Barents Sea

The research for this thesis began in 1996. The purpose was to confirm or reject the hypothesis that the life history of Northeast Arctic cod can be explained as a stationary cycle in a time series. I was rector at Aalesund University College from 1997 to 2000 and my research had to wait. In 2000 and 2001 I developed dynamic models for the most important species in the Barents Sea. The results supported the analysis from my first investigations. The next step was to look for the missing link between the 18.6-year lunar nodal cycle and the identified cycles in the Barents Sea. In 2001 I started to develop new methods to analyze climate indicators. The result was the Arctic Oscillation system theory. Wavelet analysis showed promising results and I started to analyze the biomass time series using the same analysis methods. This opened the possibility of a unified theory to explain the results from all time series.
The research on this subject has not been straightforward, partly because I did not follow the mainstream of published ideas and partly because the idea that the moon has an influence on the climate and biomass fluctuation has not been accepted by most scientists. The major problems have been to reduce complexity, to get access to data that extended over a long period of time, and to understand the complex dynamics. During this research I found that other scientists had studied the same problem earlier in the 19th century. Later, the 18.6-year cycle was estimated using a long time series, but the work failed to explain the reasons that drove this cycle length. This problem made it necessary for me to go back to the basic ideas found in early papers. I studied the early philosophy of science and general systems theory. I developed new analytical methods and new theories to explain these new results. The results were first presented at international conferences for discussion and were later published in international journals. This thesis represents a synthesis of seven papers that describe the different facets of the investigation.
