About Bermeja Island (Isla Bermeja) – Phantom Gulf Island at 22°33′N 91°22′W
Bermeja (Isla Bermeja/vermilion islet) – Gulf of Mexico phantom island charted continuously from Alonso de Santa Cruz's 1539 'El Yucatán e Islas Adyacentes' (Santa Cruz, Sebastián Cabot 1544) at 22°33′N 91°22′W on Campeche Bank, through 160 19th c. charts, Mexican textbooks and 1990s US–Mexico maritime boundary negotiations (EEZ 200 nm stake '22.5 billion barrels oil' – Missed History). UNAM 1997–2009 systematic search (RV Justo Sierra sonar, satellite) found 4000 m water with seamount at 22°38′N 90°51′W (Scorpion Reef) but no island; INEGI officially removed 2009. Seamount subsidence or intentional oil-right inflation are contending theories, but cartographic subsidence is consensus.
Why it mattersGeopolitical case-study for law-of-sea EEZ phantom land; 'Bermeja' repeatedly cited in Gulf oil negotiations before Mexico–US 2000 Western Gap treaty. Demonstrates how phantom islands affect hydrocarbon jurisdiction.

Mysteries & theories
Mysteries
- 01Whether Bermeja was tectonic subsidence of Campeche seamount vs pure cartographic ghost
- 02Alleged 1998 CIA hydrographic deletion conspiracy (Missed History debunk)
Theories
- 01Scorpion Reef (Arrecife Alacranes) seamount at 22.646°N -90.855°W is nearest real feature – likely misidentification anchor
- 02EEZ Western Gap treaty closed loophole after Bermeja removal
