A fairly well-known phenomenon called South Atlantic Anomaly (SAA) refers to the unusually weak magnetic field over South America and the southern Atlantic Ocean. And scientists acknowledge that ...

A magnetic observatory is being re-established on South Georgia to provide vital data on the 'South Atlantic Anomaly' as scientists monitor a possible reversal of the earth's magnetic field.

For years, NASA has been studying a growing anomaly in Earth’s magnetic field that scientists liken to a “dent” or “pothole in space.” It is a giant region of lower magnetic intensity ...

"Our team has been setting the pace in advancing magnetic anomaly-based navigation, from establishing statistical rigor around performance and map quality to shaping requirements for magnetic maps ...
