Researchers looking through data from NASA and the German Aerospace Center (DLR)'s Gravity Recovery and Climate Experiment (GRACE) have found an odd gravity anomaly over the Atlantic Ocean. Attempting to find the cause of the anomaly, the team found it may be associated with a "geomagnetic jerk" detected around the world. The rest of this article is behind a paywall.

There is still plenty to learn about the Earth's geomagnetic field, the magnetic field that extends from our planet's core and into space, creating the magnetosphere . One puzzle is the so-called "geomagnetic jerks" that have been detected by observatories, sometimes planet-wide.

"The main part of the geomagnetic field originates in the Earth's outer core and varies o
