Study provides evidence of a magnetic field anomaly in Southeast Asia 800 years agojavascript:;

An international team of researchers has discovered evidence of a magnetic field anomaly in Southeast Asia roughly 800 years ago. The researchers conducted an archaeomagnetic study on an iron-smelting site from Cambodia, an area currently devoid of data. The results...

NASA’s Earth scientists explore South Atlantic Anomaly

Earth’s magnetic field acts like a protective shield around the planet, repelling and trapping charged particles from the Sun. But over South America and the southern Atlantic Ocean, an unusually weak spot in the field – called the South Atlantic...

Study reveals South Atlantic magnetic anomaly is a recurring feature

In a new study, scientists from the University of Liverpool in England traced back the strange behavior of the magnetic field in the South Atlantic region and found that similar anomalies existed as far back as 8 to 11 million years ago. The South Atlantic Anomaly...

Research helps explain ongoing changes in geomagnetic field

Scientists from the University of Rochester used new data from sites in southern Africa to help explain recent and ongoing changes in Earth's magnetic field, best expressed by a deepening area of low field called the South Atlantic Anomaly. Their research...

The anomaly in the Earth’s magnetic field which has geophysicists abuzz

In this interview, EGU's Laura Roberts Artal speaks with Jay Shah, a Ph.D. student at Imperial College London, who is investigating the South Atlantic Anomaly, a patch over the South Atlantic where the Earth’s magnetic field is weaker than elsewhere on the...
