Tidal Chromatograph: Alang

The end-of-life depreciation of global maritime capital leaves a permanent geological signature, unintentionally utilizing the ocean's tides to separate industrial toxins along a 15-degree intertidal slope.

wall text

At Alang, India, the decommissioning of international maritime fleets collides with the world's most extreme tidal regime. Utilizing the Gulf of Khambhat's 13-meter spring tides, this project reframes the 15-degree intertidal mudflat as an unintended thin-layer chromatography plate. Seawater functions as the mobile solvent, carrying dismantled industrial toxins—such as tributyltin, asbestos, and lead-based anti-fouling coatings—across the fine coastal silt stationary phase. As the water recedes, compounds separate according to molecular weight and retention factors. Extracted in vertical sediment cores, these segregated toxins form a stratified, permanent geological barcode of 20th-century global trade liquidation.

shown: Installed permanently as an array of 40 vertical core-sample pillars aligned precisely along the spring tide high-water mark on Alang beach, slowly weathering into the contaminated landscape.

mechanism

Thin-Layer Chromatography (Mobile Phase) — The Gulf of Khambhat's massive 13-meter spring tides act as the chemical solvent, cyclically washing over and saturating the 10-kilometer coastline.
1. Mobile Phase Introduction
Stationary Phase Adsorption — The dense coastal mud captures industrial particulate matter as seawater recedes, effectively acting as an immense silica gel plate.
2. Stationary Phase Adsorption
Analyte Separation (Retention Factor) — Heavy metals, asbestos fibers, and anti-fouling agents segregate into distinct horizontal strata along the beach gradient based on their density and lipid solubility.
3. Analyte Separation by Retention Factor
Core Sampling and Chemical Staining — Cylindrical tubes driven 3 meters into the mudflats extract the stratified sediment, which is then cured in optical acrylic to reveal the chronological barcode of shipping collapse.
4. Geochemical Fixation and Visualization

curatorial qa (machine verdict, unedited)

SCORE 3/5 after 2 attempt(s)
READS: The core tube clearly showcases distinct anthropogenic strata positioned against the shipbreaking yard, effectively pairing the graphic diagram with the industrial beachscape.
FAILS: The tidal dynamics appear as a violent exterior splash rather than an internal, legible upward capillary percolation separating distinct chemical analytes through sediment.
