Fish welfare in a changing world: New developments and current challenges

Journal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Change of earth environment due to the decreasing geomagnetic field -The necessity of observation in Brazilian geomagnetic anomaly region-

Antarctic Record, 1996
According to recent research on rock magnetism, the geomagnetic field intensity of our planet has been monotonically decreasing for one thousand years and it will disappear after another 1000years if the present decreasing rate continues.

Shark preferences: Only subtle effects of electromagnetic field exposure and substrate type on small‐spotted catshark (Scyliorhinus canicula) behaviour

Journal of Fish Biology, EarlyView.
Abstract Offshore wind energy plays a crucial role in the transition to low‐carbon power generation. The expansion of offshore wind farms (OWFs) introduces anthropogenic electromagnetic fields (EMFs) from subsea power cables. Elasmobranchs, including sharks and rays, are sensitive to natural electric and magnetic fields used for navigation and prey ...

Geophysical update of the diameter of the Zhamanshin impact structure, Kazakhstan

Meteoritics &Planetary Science, EarlyView.
Abstract The rim of the 0.9‐Ma‐old Zhamanshin impact crater in Kazakhstan is considered to be almost completely exposed via a series of hills surrounding a central flat area, indicating an apparent diameter of 14 km. This would make Zhamanshin the second largest impact crater of the Quaternary period. However, the overall geometry of these hills is not

Models and predictions of Earth’s magnetic field based on geomagnetic observatory data

Earth, Planets and Space
Observations of the geomagnetic field taken at Earth’s surface are processed to construct a set of continuous models of the geomagnetic field and its secular variation from 1956 to 2033.

Metrology for Quantum Hardware Standardization—Charting a Pathway: A Strategic Review

IEEJ Transactions on Electrical and Electronic Engineering, Volume 21, Issue 9, Page 1282-1296, September 2026.
Advances in quantum mechanics have long underpinned metrology by enabling practical realizations of units through quantum effects. With the 2019 SI revision, traceability is anchored in defined fundamental constants, reinforcing the quantum‐mechanical basis of modern standards. In parallel, quantum technologies are transitioning from laboratory science

Integrated Multi‐Physics Characterisation of the Northern Kiruna Mining District With Machine‐Learning‐Assisted Interpretation

Geophysical Prospecting, Volume 74, Issue 7, September 2026.
ABSTRACT Integrated earth modelling aims to combine all available geoscientific information to derive one common earth model. However, combining multiple parameters in a meaningful way remains challenging. In this study, we aim to improve mineral exploration workflows through the integration of new magnetotelluric data with other geophysical and ...

Controls on Solar Wind Entry Identified Through Wind–ACE Heavy‐Ion Diagnostics

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Solar wind (SW) entry into the magnetosphere occurs through several mechanisms, but their dependence on the properties of different ion species is unknown. We compare measurements from Wind‐STICS (magnetosphere) with ACE‐SWICS (L1) to test for any preferential entry between He2+ and SW heavy ions.

Shannon information of the geomagnetic field for the past 7000 years [PDF]

Nonlinear Processes in Geophysics, 2010
The present behaviour of the geomagnetic field as expressed by the International Geomagnetic Reference Field (IGRF) deserves special attention when compared with that shown over the past few thousands of years by two paleomagnetic/archeomagnetic models ...

Twenty years of geomagnetic field observations at Mario Zucchelli Station (Antarctica)

Annals of Geophysics, 2009
During the 1986-87 austral summer a geomagnetic observatory was installed at Terra Nova Bay. During the first<br />years both geomagnetic field time variation monitoring and absolute measurements were carried out only during<br />summer ...
