Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.Abstract How much of Io's SO2 ${\text{SO}}_{2}$ atmosphere is driven by volcanic outgassing or sublimation of SO2 ${\text{SO}}_{2}$ surface frost is a question with a considerable history. We develop a time dependent surface temperature model including thermal inertia and the exact celestial geometry to model the radiation driven global structure and ...

Influences of Non‐Oberbeck–Boussinesq Effects on Tracer Transport in Icy Ocean Worlds
Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.Abstract The subsurface oceans on icy satellites are potentially habitable. To understand their habitability, we need to know how tracers with various lifetimes distribute. Convection is the main vehicle for tracer transport, and we expect convection on icy satellites to differ from regular rotating convection, because as pressure increases, water's ...

Modeling the Time‐Variability of the Ionospheric Electric Potential (TiVIE)
Space Weather, Volume 23, Issue 7, July 2025.Abstract We present a statistical model of the ionospheric electric potential derived from line‐of‐sight plasma velocity measurements from the Super Dual Auroral Radar Network. Electric potential patterns are produced using an established technique that models the ionospheric electric potential as a spherical harmonic expansion.

Earth and Space Science, Volume 12, Issue 7, July 2025.Abstract Alpine peatlands are one of the carbon reservoirs, provide vital ecosystem services, and support endangered biodiversity. However, they are globally understudied, including those in the Italian Alps, which host thousands of small sites averaging under 1 ha.

Earth and Space Science, Volume 12, Issue 7, July 2025.Abstract Africa currently accounts for 18% of the world's population yet produces less than 2% of global research. This study examines the barriers faced by African researchers in geoscience and adjacent fields to research productivity and publication, as well as explores how these scientists view collaboration with international partners.

Earth and Space Science, Volume 12, Issue 7, July 2025.Abstract Geologic and geodetic observations provide constraints on tectonic and earthquake cycle kinematics. Block models offer one approach to integrating the effects of plate rotations, elastic strain accumulation, applied basal displacements, internal block strain, and idealized pressure sources.

Mantle Flow and Anisotropy in Subduction Zones: Modeling and Clustering of Olivine Textures
Geochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.Abstract The mantle near Earth's subduction zones endures intense deformation that generates anisotropic rock textures. These textures can be observed seismically and modeled geodynamically, but the complexity of this deformation makes analyses of these textures difficult.

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.Abstract Tectonic carbon degassing is an important contributor to the global carbon cycle. South Eastern Europe is an active extensional tectonic region. This is the result of intense geodynamic events related to the closure of the Tethys Ocean, whose remnants include an ophiolite orogenic belt and the Vardar megasuture.

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.Abstract Studies of exhumed subduction shear zones indicate that metamorphism and metasomatism of the oceanic lithosphere influence the composition, structure, and rheology of megathrust faults, particularly deep along the plate boundary (>30 km). However, less is known about the effects that fluid‐mediated chemical reactions have on the rheological ...
