A multisource geomagnetic field model incorporating ocean circulation-induced magnetic field

Earth and Planetary Physics
The movement of global ocean circulation in the Earth’s main magnetic field generates a measurable induced magnetic field (about 2 nT at geomagnetic satellite altitudes).

Multi‐command wearable magnetic human‐machine interface enabled by low‐noise sensing and time‐series deep learning

InfoScience, EarlyView.
This study integrates a wrist‐worn sensing platform based on a low‐noise planar Hall magnetoresistive sensor with time‐series deep learning to enable long‐range, single‐sensor, multi‐command gesture recognition with high accuracy. Further evaluations show reliable generalization across different days, previously unseen users, wearing‐position ...

The model of the geomagnetic non-dipole field.

Journal of geomagnetism and geoelectricity, 1983
Yukutake's model separates the geomagnetic field into drifting and standing parts, not only fits well to the observed field for the past several hundred years, but also emphasizig the regularities of the westward drift of the geomagnetic non-dipole field. However, there are still some problems to be reinvestigated:a) In Yukutake's model the geomagnetic

White light reduces flight height of birds in low‐density migration corridor

The Journal of Wildlife Management, EarlyView.
We conducted an experiment to better understand the effects of artificial light at night treatments of varying spectral power distributions on in‐flight migratory bird behavior as measured by a portable radar. Broad‐spectrum white light emissions reduced avian flight height as compared to dark periods and more than other light treatments.

Response of the American equatorial ionization anomaly to 2016 Arctic sudden stratospheric warming events

Frontiers in Astronomy and Space Sciences, 2022
Apart from the rapid ionospheric response to geomagnetic forcing originating from the Sun during extreme space weather events, forcing from the lower atmosphere below still exerts a significant influence on the ionosphere during quiet-time conditions ...

FLSea: Underwater Visual–Inertial and Stereovision Forward‐Looking Data Sets

Journal of Field Robotics, EarlyView.
ABSTRACT Visibility underwater is challenging and degrades as the distance between the subject and the camera increases. That is why forward‐looking underwater computer vision tasks are difficult. We have collected underwater forward‐looking stereovision and visual–inertial image sets using two underwater imaging platforms, a stereo camera rig, and an ...

On the Regional Variability of dB/dt and Its Significance to GIC

Space Weather, 2020
Faraday's law of induction is responsible for setting up a geoelectric field due to the variations in the geomagnetic field caused by ionospheric currents. This drives geomagnetically induced currents (GICs) which flow in large ground‐based technological

The Swarm Initial Field Model for the 2014 geomagnetic field [PDF]

Geophysical Research Letters, 2015
AbstractData from the first year of ESA's Swarm constellation mission are used to derive the Swarm Initial Field Model (SIFM), a new model of the Earth's magnetic field and its time variation. In addition to the conventional magnetic field observations provided by each of the three Swarm satellites, explicit advantage is taken of the constellation ...

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.

Sudden commencement event of 17 April 2002: Aspects of the geomagnetic response at low latitudes [PDF]

, 2005
An analysis of a sudden commencement (SC) manifestation reveals a significant contribution of the polar current system which influences the long-term behavior of the H component at low-latitude ground stations located in the subsolar sector. A transition
