Geomagnetic secular variation in the Antarctic region during 1960-1975
Antarctic Record, 1982 The annual mean values of the geomagnetic three components (X, Y, Z) at 20 stations located between the South Pole and the 30°S latitude circle during 15 years from 1960 to 1975 are examined to study on the geomagnetic secular variation in the southern ...

Physics-based secular variation candidate models for the IGRF
Earth, Planets and Space, 2021 Each International Geomagnetic Reference Field (IGRF) model released under the auspices of the International Association of Geomagnetism and Aeronomy comprises a secular variation component that describes the evolution of the main magnetic field ...

Geomagnetic Intensity of Hellenistic Pottery and Stamped Rhodian Wine Amphorae From Jerusalem
Archaeometry, EarlyView.ABSTRACT Stamped amphora handles produced on Rhodes during the Hellenistic period are well suited for archaeointensity studies because they often bear the names of annually appointed magistrates (eponyms) and fabricants, allowing dating to narrow time intervals.

An Ensemble Algorithm Based Component for Geomagnetic Data Assimilation
Terrestrial, Atmospheric and Oceanic Sciences, 2015 Geomagnetic data assimilation is one of the most recent developments in geomagnetic studies. It combines geodynamo model outputs and surface geomagnetic observations to provide more accurate estimates of the core dynamic state and provide accurate ...

Geomagnetic Secular Variation Anomalies in the GDR
Journal of geomagnetism and geoelectricity, 1978 For about 25 years, measurements of the magnetic components have been carried out at repeat stations in the territory of the GDR. All measurements at common stations of the magnetic surveys for the epochs 1901, 1935, and 1957 were compared. The results of the investigation indicate secular variation anomalies with amplitudes of about 3–4 nT/year. These
