Speleothem record of geomagnetic South Atlantic Anomaly recurrence [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2018 The diminishing strength of the Earth’s magnetic dipole over recent millennia is accompanied by the increasing prominence of the geomagnetic South Atlantic Anomaly (SAA), which spreads over the South Atlantic Ocean and South America. The longevity of this feature at millennial timescales is elusive because of the scarcity of continuous geomagnetic data

Characterization of the South Atlantic Anomaly [PDF]
Nonlinear Processes in Geophysics, 2019 This research intends to characterize the South Atlantic Anomaly (SAA) by applying the power spectrum analysis approach. The motivation to study the SAA region is due to its nature. A comparison was made between the stations in the SAA region and outside

Non-monotonic growth and motion of the South Atlantic Anomaly [PDF]
Earth, Planets and Space, 2021 The South Atlantic Anomaly (SAA) is a region at Earth’s surface where the intensity of the magnetic field is particularly low. Accurate characterization of the SAA is important for both fundamental understanding of core dynamics and the geodynamo as well

Time evolution of the South Atlantic Magnetic Anomaly [PDF]
Anais da Academia Brasileira de Ciências, 2009 The South Atlantic Magnetic Anomaly (SAMA) is one of the most outstanding anomalies of the geomagnetic field. The SAMA secular variation was obtained and compared to the evolution of other anomalies using spherical harmonic field models for the 1590-2005

The South Atlantic Anomaly: the key for a possible geomagnetic reversal [PDF]
Frontiers in Earth Science, 2016 The South Atlantic Anomaly is nowadays one of the most important features of the Earth’s magnetic field. Its extent area at the Earth’s surface is continuously growing since the intensity instrumental measurements are available covering part of the ...

The South Atlantic Anomaly throughout the solar cycle [PDF]
Earth and Planetary Science Letters, 2017 Abstract The Sun–Earth's interaction is characterized by a highly dynamic electromagnetic environment, in which the magnetic field produced in the Earth's core plays an important role. One of the striking characteristics of the present geomagnetic field is denoted the South Atlantic Anomaly (SAA) where the total field intensity is unusually low and ...

The Impact of the South Atlantic Anomaly on the Aurora System
Geophysical Research LettersThe South Atlantic Anomaly (SAA) refers to a region where the strength of the magnetic field is notably weaker compared to a dipole field. While previous studies have primarily focused on its effects on the inner radiation belt, this study investigates ...

Relating the South Atlantic Anomaly and geomagnetic flux patches
Physics of the Earth and Planetary Interiors, 2017 Abstract The South Atlantic Anomaly (SAA) is a region of weak geomagnetic field intensity at the Earth’s surface, which is commonly attributed to reversed flux patches (RFPs) on the core-mantle boundary (CMB). While the SAA is clearly affected by the reversed flux region below the South Atlantic, we show that the relation between the intensity ...
