"The Body Electric"
Earth's background base frequency or "heartbeat" is an energetic matrix for life on earth
The ionosphere (a band between about 37 and 620 miles above the earth) is the part of the atmosphere that is ionized by solar radiation. Electromagnetic (EM) waves in this cavity are produced by lightning discharges inside the earth-ionosphere cavity, exciting the resonant frequencies of the cavity and filling it, much like sound waves are produced when a bell rings at its resonant frequency when struck by a hammer.
SRs are not caused by anything internal to the Earth, its crust or its core
Nikola Tesla called the Schumann field an energetic matrix for the life on Earth. It is a magnetic field that stores information, not too far-fetched, since we too use magnetic fields for storage E.g.audio/video tapes, computer disks etc.
The average fundamental Schumann resonance frequency is 7.83 Hz (fluctuates between 7.0 Hz. and 8.5 Hz), and its harmonic frequencies are 14.3, 20.8, 27.3, 33.8 Hz ... The fundamental Schumann frequency (having the highest EM field strength ) is about the same as that of alpha brain waves. Those produced by the brain in a relaxed state (When people are irritable, they produce higher frequencies).
The magnitude and frequency of the SRs are also affected by natural interruptions. Mainly lightning. Most lightning occurs over land, and lightning centers move from north to south and back over the course of a year. Also, lightning and rainfall is affected by long-term climate oscillations. Worldwide, there are an estimated 50 lightning strikes per second, each producing 0.5 - 1 Amp, which excite the Schumann resonance field.
Our environmental EMF changes throughout the day and night
Our environmental EMF changes according to our location relative to the magnetosphere. The earth rotates on a day /night cycle within the complex magnetosphere, which remains fixed in space, with one side always facing the sun. Thus, any given spot on the surface of the Earth is continually experiencing a different part of the magnetosphere's magnetic field. It is the daily rise and fall in the strength of this field at that spot on earth where we are, which affects our biological rhythms.
SR Data measured at Arrival Heights, Antarctica (AH), Sondrestromfjord, Greenland (SS), and Stanford, California (SU)
Notice the spikes produced by the European and U.S. power supply networks at 50 and 60 Hz
At SU in California, modulation frequencies at 30 and 90 Hz. result from non-linearities of the power transmission system
All sites have 82 Hz. produced by a Russian submarine communication system
A variety of other spectral peaks of unknown origin occur. Eight earth-ionosphere cavity resonances can be distinguished. Notice how the amplitude of the resonances decreases with frequency.
