“ZEVS, The Russian 82 Hz ELF Transmitter – An Extreme Low Frequency transmission-system, using the real longwaves” by Trond Jacobsen at ALFLAB, Halden in Norway, pieces together another of the Russian Large Scale Antennas and it’s use for Submarine Communications.
The Zevs transmitters nearly worldwide coverage, makes it possible to send one-way messages to submersed Russian submarines, in both the Atlantic and Pacific oceans. With the aid of ELF transmitters like the Russian Zevs, nuclear powered submarines can stay under water at operational depth with operational speed for weeks and months, out of sight for the “enemy”.
[The] CIS ELF transmitter Zevs at the Kola peninsula, [are] not exclusively used for military communication purposes. The ELF electromagnetic waves do not only penetrate water but also the ground to great depths. This property are used for geophysical research.
