  • A Persistent Non-uniformitarian Paleomagnetic Field in the Devonian? 
    van der Boon, Annique; Biggin, Andrew J.; Thallner, Daniele; Hounslow, Mark; Bono, Richard; Nawrocki, Jerzy; Wójcik, K; Paszkowski, Mariusz; Königshof, Peter; de Backer, Tim; Kabanov, Pavel; Gouwy, Sofie; VandenBerg, Richard (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    The Devonian has long been a problematic period for paleomagnetism. Devonian paleomagnetic data are generally difficult to interpret and have complex partial or full overprints– problems that arise in data obtained from ...
  • Analysis of an Updated Paleointensity Database (QPI‐PINT) for 65–200 Ma: Implications for the Long‐Term History of Dipole Moment Through the Mesozoic 
    Kulakov, Evgeniy; Sprain, Courtney; Doubrovine, Pavel; Smirnov, Aleksey V.; Paterson, Greig; Hawkins, Louise; Fairchild, Luke; Piispa, Elisa J.; Biggin, Andrew J. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    The global paleointensity database for 65–200 Ma was analyzed using a modified suite of paleointensity quality criteria (QPI) such that the likely reliability of measurements is assessed objectively and as consistently as ...
  • Possible links between long-term geomagnetic variations and whole-mantle convection processes 
    Biggin, Andrew J.; Steinberger, Bernard; Aubert, Julien; Suttie, Neil; Holme, Richard; Torsvik, Trond Helge; van der Meer, Douwe G.; Van Hinsbergen, Douwe (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2012)
    The Earth's internal magnetic field varies on timescales of months to billions of years. The field is generated by convection in the liquid outer core, which in turn is influenced by the heat flowing from the core into the ...
  • Quantitative estimates of average geomagnetic axial dipole dominance in deep geological time 
    Biggin, Andrew J.; Bono, Richard K.; Meduri, Domenico G.; Sprain, Courtney; Davies, Christopher J.; Holme, Richard; Doubrovine, Pavel V. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    A defining characteristic of the recent geomagnetic field is its dominant axial dipole which provides its navigational utility and dictates the shape of the magnetosphere. Going back through time, much less is known about ...
  • Subduction flux modulates the geomagnetic polarity reversal rate 
    Hounslow, Mark W.; Domeier, Mathew; Biggin, Andrew J. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Ascertaining the cause of variations in the frequency of geomagnetic polarity reversals through the Phanerozoic has remained a primary research question straddling paleomagnetism and geodynamics for decades. Numerical ...
