Calcium and Multi‐Isotope Constraints on Cation Exchange in Groundwater

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Cation exchange is one of the most important processes in water‐rock interaction in the presence of clay minerals, with a common Ca‐Mg‐Na exchange system. However, systematic verification of Ca isotopes for tracing cation exchange in natural environments is lacking due to overlapping factors, such as dissolution‐precipitation of Ca‐minerals ...

Soil Lead Risks Associated With Urbanization Histories in Springfield MA and Hartford CT, USA

GeoHealth, Volume 10, Issue 6, June 2026.
Abstract Due to legacy leaded products, soil Pb is generally higher in older urban centers triggering substantial implications for environmental equity. By integrating a gridded soil Pb analysis of about 150 samples each in two historically industrial cities (Hartford, CT and Springfield, MA) with block‐level census data, we tested the hypotheses that (

What Observations Would an Energetic Neutral Atom Imager Have Made During the Voyager 2 Flyby of Uranus?

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present large‐scale simulations of energetic neutral atom (ENA) emissions at Uranus from a spacecraft viewpoint. Models of magnetic field, extended hydrogen exosphere, moon‐sourced neutral tori, and proton radiation belt are implemented into a simulator to evaluate the production of ENAs for L $L$ = 1–15.

Reinvestigating the Nightside Ionosphere of Mars With 8 Years of Mars Express and MAVEN Data

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Tailward ion escape in the nightside magnetotail is one of the dominant paths of ion escape from Mars. The Martian nightside ionosphere can serve as a major reservoir for this escape channel, but its global distributions and dependence on the upstream solar wind have not been fully investigated due to observational limitations.

Mastcam‐Z Spectrophotometric Properties of Materials at the Van Zyl Overlook, Jezero Crater

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract During Sols 63–65 of Mars 2020, Mastcam‐Z multispectral (442–1022 nm) images were acquired at Van Zyl Overlook (VZO), spanning phase angles from ∼0° to 150°, to model photometric parameters for seven surface units. These units included rocks, soils, regolith, and rover tracks near the Jezero landing site.
