Extreme Low Frequency (ELF) systems are reportedly operational beneath the ice at the South Pole, used for secretive submarine communications. Eric J. Hecker notes that personnel were not informed of the hazards associated with being in close proximity to these high-power transmitters. Similar ELF installations exist in the U.S., such as one south of Fort Worth, which are heavily restricted.
