Denitrification of Lulu Town
The legitimacy of an imperial claim decays at the precise biogeochemical rate of denitrification, converting extracted terrestrial wealth into an unmeasurable atmospheric void.
Denitrification rig releasing territorial nitrogen back into the Caribbean atmosphere. · motion: volatilizing solid mass into invisible, violently dispersing gas
wall text
Under the Guano Islands Act of 1856, American sovereignty over Navassa Island was tethered directly to seabird excrement. This installation models the geopolitical lifespan of that claim through biological denitrification. Air intakes harvest volatile organic nitrogen off the cliffs (ammonification), funneling the compound into a bioreactor inoculated with Nitrosomonas cultured from the 1889 labor revolt site (nitrification). An anoxic chamber then strips the remaining oxygen atoms, liberating inert dinitrogen gas back into the open sky. By converting territorial capital into untraceable atmospheric PPM, the rig accelerates the dissolution of imperial ownership at the exact metabolic pace of bacterial respiration.

anchor facts used
- The Guano Islands Act of 1856 allowed US citizens to annex unoccupied islands containing guano, treating sovereignty as a temporary state of resource extraction.
- Navassa Island was claimed in 1857 by Peter Duncan specifically for its phosphate-rich guano deposits.
- The 1889 riot at Lulu Town by exploited African American laborers exposed the brutal, unregulated conditions of the guano trade.
- The US government's sole remaining physical marker of ownership is a 162-foot lighthouse built in 1917 and abandoned in 1929.
mechanism
- Ammonification — The raw biological input is used as a baseline metric for the island's ongoing, non-human territorial accumulation.
1. Atmospheric sampling intakes capture fresh seabird excrement vapor from the limestone cliffs, isolating volatile organic nitrogen. - Biological Nitrification — Oxidizes the contemporary resource into nitrites, acting as a biochemical clock to measure the latency of historical labor grievances.
2. The organic nitrogen is fed into an aerated titanium bioreactor containing Nitrosomonas bacteria cultivated from soil samples of the 1889 riot site. - Denitrification — Reverses the value-extraction logic of the fertilizer trade, quantifying the exact half-life of a sovereign promise as it chemically decays into void.
3. The nitrites are pumped into an anoxic chamber where denitrifying bacteria strip the oxygen atoms, forcibly converting the compound into inert dinitrogen gas. - Gas Volatilization and Pressurization — Transforms the unmeasurable abstraction of legal abandonment into a measurable, destructive physical force.
4. The inert dinitrogen gas is continuously exhausted into the sealed interior of the abandoned 1917 lighthouse until the internal atmospheric pressure structurally fractures the masonry.

- Hans Haacke's 'Rhinewater Purification Plant' (1972) — Shifts the focus from ecological remediation of pollutants to the biogeochemical quantification of historical exploitation.
- Fritz Haber and Carl Bosch's Haber-Bosch Process (1909) — Inverts the artificial fixation of nitrogen for agriculture by forcing an artificial denitrification of sovereign territory.
- Tega Brain's 'Deep Swamp' (2018) — Expands the use of autonomous wetland environments to measure non-human political agency over century-long timescales.
curatorial qa (machine verdict, unedited)
SCORE 2/5 after 1 attempt(s)
READS: The physical placement of an industrial chemical apparatus among the island's arid limestone ruins, alongside the brass nitrogen-isotope analyzer artifact, effectively anchors the 1856 Guano Islands Act context and chemical extraction theme.
FAILS: The video relies on stock explosion compositing and sudden billowing smoke plumes rather than conveying the continuous biochemical conversion of organic nitrogen into invisible atmospheric gas. The bacterial oxidation and anoxic denitrification steps remain visually unreadable.
