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.

Production of definitive data from Indonesian geomagnetic observatories [PDF]
Geoscientific Instrumentation, Methods and Data Systems, 2021 Measurement of the geomagnetic field in Indonesia is undertaken by the Meteorological, Climatological, and Geophysical Agency (BMKG). Routine activities at each observatory include the determination of declination, inclination, and total field using ...

Modelling of geomagnetic induction in pipelines [PDF]
Annales Geophysicae, 2002 Geomagnetic field variations induce telluric currents in pipelines, which modify the electrochemical conditions at the pipe/soil interface, possibly contributing to corrosion of the pipeline steel.

A gaussian model for simulated geomagnetic field reversals [PDF]
Physics of the Earth and Planetary Interiors, 2016 Field reversals are the most spectacular changes in the geomagnetic field but remain little understood. Paleomagnetic data primarily constrain the reversal rate and provide few additional clues. Reversals and excursions are characterized by a low in dipole moment that can last for some 10kyr.

Geomagnetic data from the GOCE satellite mission
Earth, Planets and Space, 2022 The Gravity field and steady-state Ocean Circulation Explorer (GOCE) is part of ESA’s Earth Explorer Program. The satellite carries magnetometers that control the activity of magnetorquers for navigation of the satellite, but are not dedicated as science

Regional Geomagnetic Field Model for Croatia at 2009.5 [PDF]
Acta Geophysica, 2016 Geomagnetic data of north, east and vertical components at Croatian repeat stations and ground survey sites, as well as European geomagnetic observatories and repeat stations, were used to obtain a regional geomagnetic model over Croatia at 2009.5 epoch.

Can the comprehensive model phase 4 (CM4) predict the geomagnetic diurnal field for days away from quiet time? [PDF]
Annales Geophysicae, 2016 The most recent comprehensive model (CM4) of the geomagnetic field (Sabaka et al., 2004) has been used in conjunction with geomagnetic ground observatory station data to analyse and study the geomagnetic diurnal variation field for days away from ...

Modeling and Predicting the Short‐Term Evolution of the Geomagnetic Field [PDF]
Journal of Geophysical Research: Solid Earth, 2018 AbstractWe propose a reduced dynamical system describing the coupled evolution of fluid flow and magnetic field at the top of the Earth's core between the years 1900 and 2014. The flow evolution is modeled with a first‐order autoregressive process, while the magnetic field obeys the classical frozen flux equation.

Fast computation of the geoelectric field using the method of elementary current systems and planar Earth models [PDF]
Annales Geophysicae, 2004 The method of spherical elementary current systems provides an accurate modelling of the horizontal component of the geomagnetic variation field. The interpolated magnetic field is used as input to calculate the horizontal geoelectric field.
