Twenty years of geomagnetic field observations at Mario Zucchelli Station (Antarctica)
Annals of Geophysics, 2009 During the 1986-87 austral summer a geomagnetic observatory was installed at Terra Nova Bay. During the first<br />years both geomagnetic field time variation monitoring and absolute measurements were carried out only during<br />summer ...

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.

Croatian geomagnetic field maps for 2008.5 epoch
Annals of Geophysics, 2013 The status of the Croatian Geomagnetic Repeat Stations Network (CGRSN) and Croatian Geomagnetic Network for Field Mapping (CGNFM), completed in 2010, was described. Standard and new survey practices as well as reduction techniques were presented.

Geomagnetic jerks characterization via spectral analysis [PDF]
Solid Earth, 2012 In this study we have applied spectral techniques to analyze geomagnetic field time-series provided by observatories, and compared the results with those obtained from analogous analyses of synthetic data estimated from models. Then, an algorithm is here

The influence of the geomagnetic field and of the uncertainties in the primary spectrum on the development of the muon flux in the atmosphere [PDF]
, 2004 In this paper we study the sensitivity of the flux of atmospheric muons to uncertainties in the primary cosmic ray spectrum and to the treatment of the geomagnetic field in a calculation.

Changes in cosmic ray cut-off rigidities due to secular variations of the geomagnetic field [PDF]
Annales Geophysicae, 1997 An analytical expression is derived for the cutoff rigidity of cosmic rays arriving at a point in an arbitrary direction, when the main geomagnetic field is approximated by that of an eccentric dipole.

Did Open Solar Magnetic Field Increase during the Last 100 Years: A Reanalysis of Geomagnetic Activity [PDF]
, 2004 Long-term geomagnetic activity presented by the aa index has been used to show that the heliospheric magnetic field has more than doubled during the last 100 years. However, serious concern has been raised on the long-term consistency of the aa index and

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.
