Equivalent Monopole Source of the Geomagnetic South Atlantic Anomaly

Pure and Applied Geophysics, 2009
The South Atlantic magnetic Anomaly (SAA) is an important feature of the present geomagnetic field. In this paper we model the space–time evolution of this anomaly over the past 400 years in terms of the resultant between a decrease of a global axial dipole and an increase of a virtual local monopole source.

Magnetic anomalies in the South Atlantic and ocean floor spreading

Journal of Geophysical Research, 1968
Magnetic profiles across the South Atlantic Ocean from the Rio Grande rise and Argentine basin to the southwest coast of Africa and between 25° and 50°S are presented. Anomalies have been correlated from profile to profile, and the resulting magnetic pattern is parallel to and symmetric about the axis of the mid-Atlantic ridge.

South Atlantic Anomaly Evolution Seen by the Proton Flux

Journal of Geophysical Research: Space Physics
AbstractThe SEM‐2 (Space Environment Monitor‐2) instrument embedded on the NOAA‐15 Low Earth Orbit satellite provides measurements of trapped protons in the Van Allen inner belt from 1998 to nowadays. This continuous set of measurements enables us to study the dynamics of the South Atlantic Anomaly (SAA) over more than two solar cycles, particularly ...
