Osireion Temperature Anomaly Debunked as Measurement Error. 2011 report claimed water in two piezometers was 10°C (18°F) warmer than surrounding water 2004 measurements showed temperatures within 3°F throughout entire canal 2010 measurements showed temperatures within 2°F under pumping and non-pumping conditions

A 2011 report claimed Osireion water was 10°C warmer than surroundings — but later measurements showed temps within 3°F throughout. The 2010 data actually shows Osireion is COOLER than nearby wells by 2-5°C. That initial anomaly? Probably improper sensor handling: body heat, sunlight on equipment, or sediment interference. Good science corrects itself!

Key Facts

  • 2011 report claimed water in two piezometers was 10°C (18°F) warmer than surrounding water
  • 2004 measurements showed temperatures within 3°F throughout entire canal
  • 2010 measurements showed temperatures within 2°F under pumping and non-pumping conditions
  • 2010 data: central island 23.4°C, Roman measure 23.6°C, nearby wells 1.9-4.7°C higher
  • Cooler Osireion temperature attributed to subterranean location and deeper aquifer water source
  • Piezometer anomalies likely caused by improper handling: body heat, sunlight on metal casings, or sediment embedding
