Evaluating Water Levels From the Surface Water and Ocean Topography (SWOT) Mission in a Hyper‐Tidal Coastal and Estuarine Environment

Earth and Space Science, Volume 12, Issue 7, July 2025.
Abstract The launch of the Surface Water and Ocean Topography (SWOT) satellite in December 2022 started a new era of swath altimetry, introducing an unprecedented global data set of high‐resolution two‐dimensional water level imagery. During its initial calibration and validation phase (cal/val), SWOT conducted daily observations for 3 months providing

Is One Sample Enough? Testing the Importance of Lateral Sedimentary Variability in Cyclostratigraphy

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.
Abstract Cyclostratigraphic studies of sedimentary rocks traditionally sample assuming that one sample per sedimentary horizon is sufficient. But is one sample enough? This is important to address because if two or more measurements per horizon improve data quality, then sampling schemes should strike a balance between sampling resolution ...

Mercury Deposition in South China Across the Ordovician‐Silurian Transition: Implications for Climate Change

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.
Abstract Most of the global climate changes are closely associated with volcanic activity. However, the link between global cooling during the Ordovician‐Silurian (O‐S) transition and volcanism remains unclear due to limited constraints on large volcanic events before, during, and after the peak of the Hirnantian glaciation (PHG). Here, we present high‐

The Ionopause at Mars and Its Correlation With Magnetic Topology and Plasma Pressure

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract We utilize Mars Atmosphere and Volatile Evolution (MAVEN) observations to investigate the ionopause boundary at Mars, the formation process of which is not yet well described. We focus on the eighth deep dip campaign (DD8), which consists of 50 consecutive orbits, and we develop an automated routine to identify ionopause boundaries in electron

Estimating Solar Wind Charge Exchange Generated Soft X‐Rays in the Jovian Magnetosheath

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract Solar Wind Charge eXchange (SWCX) generated soft x‐rays are used extensively to study the interfaces between charged and neutral particles throughout the solar system. This paper outlines the development of a model of Jupiter's magnetosheath using magnetohydrodynamic derived boundary equations and a combination of in situ Juno measurements and

Evaluating Nudging Techniques in Implementing the Lower Atmosphere Variability Induced by Tides and Gravity Waves Into the TIEGCM

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract We implement a nudging module into the Thermosphere Ionosphere Electrodynamics General Circulation Model (TIEGCM) to identify effective techniques for incorporating global‐scale tides and medium‐scale gravity waves (GWs) that induce ionospheric variability.

Diffusive Equilibrium: Modeling Anisotropic Maxwellian and Kappa Field Line Distributions in Io's Plasma Torus Using Multi‐Fluid and Kinetic Approaches

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract Modeling density distributions along Jupiter's magnetic field lines is essential for understanding the Io plasma torus, moon plasma interactions, and plasma throughout the magnetosphere. This study compares multi‐fluid and kinetic approaches to diffusive equilibrium and the effects of different plasma distribution functions and anisotropy.

The Influence of Interior Structure and Thermal State on Impact Melt Generation Upon Large Impacts Onto Terrestrial Planets

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract We investigate the melt production of planetary impacts as a function of planet size (R/REarth $R/{R}_{\text{Earth}}$ = 0.1–1.5), impactor size (L $L$ = 1–1,000 km), and core size ratio (Rcore/R ${R}_{\text{core}}/R$ = 0.2–0.8) using a combination of parameterized convection models and fully dynamical 2D impact simulations.

Scour Pits in the Medusae Fossae Formation and Olympus Mons Region on Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract The Medusae Fossae Formation (MFF) covers a region of Mars located to the southwest of the Olympus Mons shield volcano. The nature of this formation has been under debate for over 30 years. In order to better understand the MFF, we investigated scour pits or V‐shaped depressions carved into many places across the MFF.
