  "term": "External disturbance field",
  "field": "Oil and gas",
  "definition": "Magnetic or gravitational fields originating from sources outside the Earth's interior, such as solar activity or lunar tides, that can interfere with geophysical measurements. These fields introduce noise into magnetic and gravity surveys, requiring careful identification and removal during data processing. Geomagnetic storms are a common source of such disturbances in magnetic data.",
