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.

Does the magnetosphere behave differently on weekends? [PDF]
Annales Geophysicae, 2002 Global geomagnetic activity has been suggested to be enhanced during weekends above the weekly average after 1930. Before the 1930s, weekends and weekdays were found to be equally active.

Earth, Planets and Space, 2022 Cosmogenic radionuclide records (e.g., 10Be and 14C) contain information on past geomagnetic dipole moment and solar activity changes. Disentangling these signals is challenging, but can be achieved by using independent reconstructions of the geomagnetic

Solar wind and geomagnetism: toward a standard classification of geomagnetic activity from 1868 to 2009 [PDF]
Annales Geophysicae, 2012 We examined solar activity with a large series of geomagnetic data from 1868 to 2009. We have revisited the geomagnetic activity classification scheme of Legrand and Simon (1989) and improve their scheme by lowering the minimum Aa index value for ...

Dynamics of Electron Flux in the Slot Region and Geomagnetic Activity
Space Weather, 2021 The slot region between the radiation belts in the magnetosphere is statistically less populated by the energetic electrons, which makes it attractive in the design considerations of the satellite missions.

Long-term trends of foE and geomagnetic activity variations [PDF]
Annales Geophysicae, 2003 A relationship between foE trends and geomagnetic activity long-term variations has been revealed for the first time. By analogy with earlier obtained results on the foF2 trends it is possible to speak about the geomagnetic control of the foE ...

Multiscale variation model and activity level estimation algorithm of the Earth's magnetic field based on wavelet packets [PDF]
Annales Geophysicae, 2018 We suggest a wavelet-based multiscale mathematical model of geomagnetic field variations. The model is particularly capable of reflecting the characteristic variation and local perturbations in the geomagnetic field during the periods of increased ...

EARTHQUAKES AND GEOMAGNETIC DISTURBANCES
Solar-Terrestrial Physics, 2020 The article addresses the problem of the connection of earthquakes with geomagnetic phenomena. We have carried out an experimental study using a method based, firstly, on the separation of periods of geomagnetic activity into extremely quiet and ...
