The Irreversible Extinction of the Kwon Coral Sea Tide-Pulse Cartography House

The Kwon House was built in 1900 on a remote southern Korean island for Jun-Seo Kwon (1866–1913), a coral sea tide cartographer responsible for tracking ocean pulse rhythms, mapping reef current oscillations, and documenting tidal synchronization patterns used for coastal navigation and fishing safety planning.
The residence functioned as both home and marine mapping station, where Kwon and his assistants recorded tidal amplitude cycles, measured reef current drift timing, and compiled sea-pulse ledgers used to predict coastal flood behavior and navigation windows across island waterways.

The decline began in 1909 when centralized hydrographic bureaus introduced mechanized ocean buoys and satellite-linked tide prediction systems, replacing manual coral-based tide cartography.
At the same time, a sequence of unusual seismic underwater shifts disrupted reef stability, altering tidal resonance patterns beyond recorded historical behavior.
Sea charts stopped matching reality. Field surveys were discontinued. The house lost its purpose.

By 1913, Jun-Seo Kwon was formally removed from hydrographic service after national maritime authorities consolidated all tidal prediction systems under automated buoy networks and centralized naval computation offices.
His final tide pulse ledger remained open in the living room, documenting an incomplete ocean rhythm cycle that was never resolved after a major reef current inversion event.
The Kwon House remains submerged in coastal silence, its tides unmeasured, its systems obsolete, and its rooms slowly fading into salt, coral, and stillness.
