Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement
Geophysical Monograph Series, Page 27-82., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Can core-surface flow models be used to improve the forecast of the Earth's main magnetic field? [PDF]
, 2008 [1] Geomagnetic main field models used for navigation are updated every 5 years and contain a forecast of the geomagnetic secular variation for the upcoming epoch. Forecasting secular variation is a difficult task.

Geomagnetic Dipole Changes and Upwelling/Downwelling at the Top of the Earth's Core
Frontiers in Earth Science, 2018 The convective state of the top of Earth's outer core is still under debate. Conflicting evidence from seismology and geomagnetism provides arguments for and against a thick stably stratified layer below the core-mantle boundary.

Geomagnetic secular variation [PDF]
Eos, Transactions American Geophysical Union, 1971 This review attempts to reference the works on geomagnetic secular change that have appeared by authors based, even if temporarily, in the United States since 1967. It is thus an extension of the last portion of the paper given for the 1967 ‘Main Geomagnetic Field’ IUGG report [Cain, 1967], excluding the topics of field models and magnetic surveys ...

Free core nutation: new large disturbance and connection evidence with geomagnetic jerks [PDF]
, 2015 Variations in free core nutation (FCN) are connected with various processes in the Earth's fluid core and core-mantle coupling, which are also largely responsible for the geomagnetic field variations, particularly the geomagnetic jerks (GMJs). A previous

Dynamic mode decomposition of the geomagnetic field over the last two decades
Earth and Planetary Physics, 2023 Earth's magnetic field, which is generated in the liquid outer core through the dynamo action, undergoes changes on timescales of a few years to several million years, yet the underlying mechanisms responsible for the field variations remain to be ...

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.
