Electromagnetic Trophic Cascade: 153-252 kHz
The eradication of megawatt longwave infrastructure triggers an electromagnetic trophic cascade, where the sudden absence of apex ground-wave signals allows parasitic urban switching-noise to colonize and permanently overgraze the terrestrial bandwidth.
Electrolytic core sample oxidizing under unmasked ambient switching noise post-transmitter shutdown. · motion: stratifying digital noise over the collapsing carrier wave
wall text
When megawatt longwave radio transmitters are decommissioned, their massive ground-wave carrier signals disappear from the spectrum, removing the primary electromagnetic force that masked ambient radiation. This work transposes ecological apex predator removal to the electromagnetic spectrum. Without dominant carrier waves from facilities like Donebach or Droitwich, low-level high-frequency switching noise from unshielded LED drivers and solar inverters proliferates unchecked. By harvesting this parasitic radio-frequency noise floor through abandoned ground-radial earth arrays, the installation rectifies ambient interference into low-voltage DC current. This energy continuously plates dark electrolytic oxidation layers onto copper core samples, physically recording the unstructured sprawl of post-broadcast spectral biomass directly into corroding metal.

anchor facts used
- On March 2, 2018, the twin 363-meter masts of the Donebach 153 kHz transmitter were explosively demolished.
- The Droitwich 198 kHz transmitter relies on a dwindling global stockpile of Excitron glass thermionic valves to maintain its carrier wave.
- Longwave ground-wave signals physically couple with the Earth's surface, penetrating deep valleys, subterranean soil, and seawater.
mechanism
- Apex predator removal — The scheduled demolitions of European megawatt transmitters are treated as sudden extinction events, instantly severing the massive, structured electromagnetic fields that previously organized the local radio spectrum.
1. Extirpation of the Apex Emitter - Mesopredator release — Continuous spectral monitoring records the rapid influx and dominance of low-power parasitic emissions from LED drivers and solar inverters, which were previously suppressed and masked by the megawatt broadcasts.
2. EMI Mesopredator Release - Herbivore overgrazing / Biomass accumulation — The accumulated unstructured digital noise floor is captured via induction arrays, passed through a rectifier, and deposited as physical layers of electrolytic rust on subterranean copper core samples.
3. Parasitic Biomass Accumulation - Ecosystem state shift / Desertification — The physical core samples permanently solidify into an unreadable, chaotic crust of oxidized noise, chemically documenting the irreversible transition of the 150-300 kHz band into pure industrial exhaust.
4. Spectral Desertification
lineage
- Katie Paterson, 'Vatnajökull (the sound of)' — Inverts Paterson's transmission of a disappearing glacier via phone line by instead recording the disappearance of the long-range transmission medium itself.
- Christina Kubisch, 'Electrical Walks' — Builds on Kubisch's auditory mapping of urban electromagnetic fields by historicizing them as an invasive species replacing a dying megastructure.
- Robert Smithson, 'Strata: A Geophotographic Fiction' — Translates Smithson's geological deep time into electromagnetic stratigraphy, charting the physical fossilization of the radio spectrum.
curatorial qa (machine verdict, unedited)
SCORE 3/5 after 2 attempt(s)
READS: The spectral survey artifact clearly maps transmitter deactivation to an explosion of high-density parasitic RF noise, and the transmitter site setting establishes proper physical context.
FAILS: The video relies on radiating white lightning VFX and sudden flaking debris rather than showing gradual electrolytic crust stratification driven by rectified ambient noise.
