Attenuation Research: A Case for Lake Tanganyika.
Abstract
The results of the recent Lake Superior experiment indicate that the anomalous low frequency attenuation observed in sea water also exists in freshwater. Although this would tend to eliminate some possible explanations such as dissolved salts, it does not uniquely determine the cause of the anomaly. In order to acertain which of the remaining possibilities, chemical relaxation, dissolved sediments, or channel leakage is correct, another experiment must be performed in water of a markedly different temperature. The ideal location is Lake Tanganyika. Its average water temperature is above 22C as compared to 4C for most oceans and Lake Superior. If the anomalous attenuation is due to a chemical process, the relaxation frequency would be roughly doubled by this temperature change.
