High‐Speed Electron Flows in the Earth Magnetotail

AGU Advances, Volume 6, Issue 2, April 2025.
Abstract High‐speed electron flows (HSEFs) play a crucial role in the energy dissipation and conversion processes within the terrestrial magnetosphere and can drive various types of plasma waves and instabilities, affecting the electron‐scale dynamics.

Deciphering Degassing Mechanisms of He and H2 ${\mathbf{H}}_{\mathbf{2}}$ at the Sedimentary Basin‐Basement Interface by Surface Geophysics and Gas Geochemistry

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract With the increasing importance of the carbon footprint of transport, new sources, closer to consumers, of H2 ${\mathrm{H}}_{2}$ and He are explored. Within this context, we present a combined near‐surface geophysical imaging, soil gas sampling, and bubbling well gas sampling approach to study fluid and gas pathways near a fault system in the ...

Evolution of Force‐Free Magnetic Structure in the Dayside Ionosphere of Mars

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract Magnetic fields measured in the ionosphere of Mars by the magnetometers onboard the Mars Atmosphere and Volatile EvolutioN (MAVEN) and the Mars Global Surveyor (MGS) spacecraft display a wide range of spatial scales, ranging from global to small‐scale.

Topographic Drag at the Core‐Mantle Interface

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract The length of day variations with periods from five to one hundred years are mainly due to core‐mantle interactions. Assuming a differential velocity between the core and the mantle, we investigate the pressure coupling on a core‐mantle boundary (CMB) interface with topography. Including rotation, buoyancy, and magnetic effects in local models

Impacts Into Titan's Methane‐Clathrate Crust as a Source of Atmospheric Methane

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract Titan is the only icy satellite in the solar system with a dense atmosphere. This atmosphere is composed primarily of nitrogen with a few percent methane, which supports an active, methane‐based hydrological cycle on Titan. The presence of methane, however, is intriguing, as its lifetime is likely much shorter than the age of the solar system ...
