Today I picked up my first fins from Mark at the Dive Bunker in Burntisland, Fife. Today was also one of those days when I felt that I’d been shown a key to a door, a chance conversation with someone that brought together a few areas of thought; thoughts which were also presented with an opportunity to be transplanted onto something concrete for a structured course of investigation.

One of the first researchers to study the effect of solar activity on mankind was a historian in Russia, Professor Aleksandr Chizhevsky (1897-1964), who is considered by many as the father of heliobiology. Chizhevsky’s main interest was sunspots, which he correlated with human activity.

As white light travels through water it is not only refracted and scattered, it is absorbed or 'attenuated' by the water. Varying wavelengths, or colours, are absorbed at differing depths; organic matter also adding to this absoption.

These are my presentation notes from the Maxwell City workshop in June this year.

Extremely low frequency transmitters were developed for communication with deeply submerged submarines at depths of more than 200 metres and under polar ice-caps. Submarines below this depth are undetectable by radar and other non-acoustic systems.
