Latitudinal dependence of geomagnetically induced currents during geomagnetic storms

Annals of Geophysics, 2019
Major geomagnetic storms drive rapid intensification and variability of magnetospheric and iono- spheric current systems that give rise to large ground-induced currents (GIC). Space weather as- sociated GIC pose a serious threat to the reliability of power-transmission systems and other elec- trically conducting infrastructure such as oil and gas ...

Uncovering Archaeological Treasures at Saruq al‐Hadid, UAE: Insights From Ground Penetrating Radar and Magnetic Data

Archaeological Prospection, EarlyView.
ABSTRACT Saruq al‐Hadid, located at the edge of the Rub Al‐Khali desert near Dubai's southern border with Abu Dhabi, is among the region's richest archaeological sites. Renowned for its historical role in metallurgy, trade and human habitation, the site was occupied from the Umm an‐Nar period through the post–Iron Age. Despite its significance, much of

A 3-Phase Current Transducer based on microfluxgate sensors [PDF]

, 2019
Novel 3-phase DC/AC current transducer for 3-phase current lines is based on 8 integrated fluxgate sensors. Using full information from each sensor rather than gradiometric pairs, we suppress crosstalk between individual phases and external magnetic ...

Composite‐Field Annealing Enables Superior High‐Temperature Noise Stability in Fluxgate Sensors With Co‐Rich Amorphous Microwires

Rare Metals, EarlyView.
ABSTRACT Fluxgate sensors with Co‐rich amorphous microwires, widely used for their low noise in magnetic field measurements, encounter significant challenges in high‐temperature environments such as well drilling and geological exploration. Prolonged thermal aging degrades the performance of Co‐rich amorphous microwires, resulting in increased noise ...
