Evidence for a geomagnetic jerk in 1990 across Europe
Annals of Geophysics, 1995 The analysis of geomagnetic data from magnetic observatories demonstrated the existence of very rapid changes, or jerks, in the secular variation, especially the occurrence of the well known geomagnetic jerks of 1969 and 1978.

After some 350 years – zero declination again in Paris [PDF]
History of Geo- and Space Sciences, 2016 The main part of the geomagnetic field – produced by a dynamo process in the Earth's outer core – changes its direction and strength in time, over timescales from months to centuries, even millennia.

Dependence of the velocity changes of secular variations on the position of observatory and time
Геофизический журнал, 2021 According to the data of world observatories net secular variations of geomagnetic fields from internal and outer sources have been studied. Averaged 3-year data have been used for this purpose.

Geomagnetic secular variation 1995–2000 [PDF]
Journal of Geophysical Research: Solid Earth, 2003 A study was done to determine the difficulty of obtaining a field model for 1995 using magnetic observations taken since that epoch. Ørsted vector data taken from 1999 to 2001 in conjunction with scalar data from all surface ship surveys and secular variation data from magnetic observatories taken since 1995 were utilized.

Centennial to millennial geomagnetic secular variation [PDF]
Geophysical Journal International, 2006 SUMMARY A time-varying spherical harmonic model of the palaeomagnetic field for 0‐7 ka is used to investigate large-scale global geomagnetic secular variation on centennial to millennial scales. We study dipole moment evolution over the past 7 kyr, and estimate its rate of change using the Gauss coefficients of degree 1 (dipole coefficients) from the ...
