  • On improving the selection ... On improving the selection of Thellier-type paleointensity data
    Paterson, Greig A.; Tauxe, Lisa; Biggin, Andrew J. ... Geochemistry, geophysics, geosystems : G3, April 2014, Letnik: 15, Številka: 4
    Journal Article
    Recenzirano
    Odprti dostop

    The selection of paleointensity data is a challenging, but essential step for establishing data reliability. There is, however, no consensus as to how best to quantify paleointensity data and which ...

  • Quantitative estimates of a... Quantitative estimates of average geomagnetic axial dipole dominance in deep geological time
    Biggin, Andrew J; Bono, Richard K; Meduri, Domenico G ... Nature communications, 11/2020, Letnik: 11, Številka: 1
    Journal Article
    Recenzirano
    Odprti dostop

    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, ...

  • Solving the mystery of the ... Solving the mystery of the 1960 Hawaiian lava flow: implications for estimating Earth's magnetic field
    Grappone, J Michael; Biggin, Andrew J; Hill, Mimi J Geophysical journal international, 09/2019, Letnik: 218, Številka: 3
    Journal Article
    Recenzirano
    Odprti dostop

    SUMMARY Studying historic lava flows provides a rare comparison between direct measurements of the Earth's magnetic field and the field information recorded in the rock record. Connecting direct and ...

  • Latitude Dependence of Geom... Latitude Dependence of Geomagnetic Paleosecular Variation and its Relation to the Frequency of Magnetic Reversals: Observations From the Cretaceous and Jurassic
    Doubrovine, Pavel V.; Veikkolainen, Toni; Pesonen, Lauri J. ... Geochemistry, geophysics, geosystems : G3, March 2019, 2019-03-00, 20190301, Letnik: 20, Številka: 3
    Journal Article
    Recenzirano
    Odprti dostop

    Nearly three decades ago paleomagnetists suggested that there existed a clear link between latitude dependence of geomagnetic paleosecular variation (PSV) and reversal frequency. Here we compare the ...

  • First palaeointensity data ... First palaeointensity data from the cryogenian and their potential implications for inner core nucleation age
    Lloyd, Simon J; Biggin, Andrew J; Halls, Henry ... Geophysical journal international, 07/2021, Letnik: 226, Številka: 1
    Journal Article
    Recenzirano
    Odprti dostop

    SUMMARY The timing of inner core nucleation is a hugely significant event in Earth's evolution and has been the subject of intense debate. Some of the most recent theoretical estimates for the age of ...

  • New Paleointensity Data Sug... New Paleointensity Data Suggest Possible Phanerozoic‐Type Paleomagnetic Variations in the Precambrian
    Lloyd, Simon J.; Biggin, Andrew J.; Li, Zheng‐Xiang Geochemistry, geophysics, geosystems : G3, October 2021, 2021-10-00, 20211001, 2021-10-01, Letnik: 22, Številka: 10
    Journal Article
    Recenzirano
    Odprti dostop

    The state of the geomagnetic field throughout the Precambrian era is largely unknown. Approximately 8% of global paleointensity records account for ∼4 billion years of Earth history. Despite this ...
