Evolution of the Earth's magnetic field strength in northwestern Argentina during the last two millennia: Towards the improvement of south American geomagnetic paleosecular variation curve

Geomagnetic Field Intensity During the First Millennium BCE From Royal Judean Storage Jars: Constraining the Duration of the Levantine Iron Age Anomaly

“…Among these materials, archaeological artifacts are nearly optimal recorders of the ancient field due to their wide abundance, suitable magnetic properties (Brown et al, 2021), and our ability to date them precisely. Archaeomagnetic intensity (archaeointensity) data published in the past few decades have enabled the construction of regional geomagnetic intensity variation curves (Bonilla-Alba et al, 2021;Cai et al, 2017;Garcia-Ruiz et al, 2022;Genevey et al, 2016Genevey et al, , 2020Genevey et al, , 2021Goguitchaichvili et al, 2023;Herve et al, 2019;Kovacheva et al, 2014;Osete et al, 2020;Rivero-Montero et al, 2021;Schnepp et al, 2020;Tema & Lanos, 2021) and the development of global geomagnetic models (Arneitz et al, 2019;Campuzano et al, 2019;Constable et al, 2016;Korte et al, 2019;Nilsson et al, 2022;Pavon-Carrasco et al, 2014;Schanner et al, 2022) which have significantly improved our understanding of the temporal evolution of the global field and the nature of flow patterns in the outer core. With the understanding that the rate of change in field intensity can exceed 10 μT per century (Gallet et al, 2020(Gallet et al, , 2021Genevey et al, 2021;Kostadinova-Avramova et al, 2021;Osete et al, 2020;Rivero-Montero et al, 2021;Shaar et al, 2011Shaar et al, , 2022, it became clear that the temporal resolution of archaeointensity datasets should be at least one data point per century.…”
