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

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 ...

Impact of the South Atlantic Anomaly on radiation exposure at flight altitudes during solar minimum [PDF]
Scientific Reports, 2023 The South Atlantic Anomaly (SAA) is a geographical region over the South Atlantic Ocean where the inner Van Allen radiation belt extends down particularly close to Earth.

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

The CHAOS-7 geomagnetic field model and observed changes in the South Atlantic Anomaly [PDF]
Earth, Planets and Space, 2020 We present the CHAOS-7 model of the time-dependent near-Earth geomagnetic field between 1999 and 2020 based on magnetic field observations collected by the low-Earth orbit satellites Swarm, CryoSat-2, CHAMP, SAC-C and Ørsted, and on annual differences of

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 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 ...
