- Magnetic anomaly - Wikipedia
In geophysics, a magnetic anomaly is a local variation in the Earth's magnetic field resulting from variations in the chemistry or magnetism of the rocks Mapping of variation over an area is valuable in detecting structures obscured by overlying material
- Dont Panic: The South Atlantic Anomaly Is Expanding | Weather. com
Scientists discovered Earth’s magnetic field is weakening over the Atlantic Ocean, but what does that mean for life on the ground?
- Magnetic anomaly map of North America | U. S. Geological Survey
The North American magnetic anomaly map derived from the digital database provides a comprehensive magnetic view of continental-scale trends not available in individual data sets, helps link widely separated areas of outcrop, and unifies disparate geologic studies
- Earth’s Magnetic Weak Spot: What’s Really Going On, And Should We . . .
Scientists discovered Earth’s magnetic field is weakening over the Atlantic Ocean, but what does that mean for life on the ground?
- What Are Magnetic Anomalies and What Causes Them?
Magnetic anomalies are caused by variations in the magnetic properties of crustal rocks Rocks contain magnetic minerals, such as magnetite, and the concentration of these minerals determines how strongly a rock influences the local magnetic field
- NASA Is Watching a Huge Anomaly Growing in Earths Magnetic Field
For years, NASA has monitored a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest Africa
- Earth’s magnetic field has a dent, and NASA is watching closely
A massive region of lower magnetic intensity, known as the South Atlantic Anomaly (SAA), has appeared above our planet This dent in Earth’s magnetic field, or “space pothole,” stretches from South America to southwest Africa
- Magnetic anomaly | geophysics | Britannica
A marine magnetic anomaly is a variation in strength of Earth’s magnetic field caused by magnetism in rocks of the ocean floor Marine magnetic anomalies typically represent 1 percent of the total geomagnetic field strength
