Subsoil Carbon and δ13C Spatial Patterns Reveal Land Use Legacy in a Sandy Subtropical Ecotone in Brazil

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Soil organic carbon (SOC) storage represents one of the most critical ecosystem services provided by soils, yet scientific assessments frequently focus on surface layers, overlooking deeper horizons. In this study, we investigated SOC stocks and spatial patterns of soil δ13C across three contrasting land use and land cover (LULC) types in ...

Microbial Ecology of the Heterogeneous Terrestrial Deep Biosphere Over 4 years in the Deep Mine Microbial Observatory (DeMMO)

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract The deep continental subsurface hosts a large, diverse, and poorly characterized microbiome. The geochemistry and microbiology of deep subsurface sites are closely linked and influenced by geological, hydrological, and anthropogenic factors. The Deep Mine Microbial Observatory (DeMMO; Lead, SD) was established in 2015 to provide stable portals

Basement Geometry and Cover‐Basement Relationships in the Central‐Western Jaca‐Pamplona Basin (Southern Pyrenees): Along‐Strike Variations and Role of Structural Inheritance

open access: yesTectonics, Volume 45, Issue 6, June 2026.
Abstract This study presents a detailed, geometrical characterization of the central‐western domain of the Jaca‐Pamplona Basin based on a combined interpretation of seismic and surface data and the construction of four serial cross‐sections. For the studied portion of the basin, our results highlight that the basement is notably folded and faulted and ...

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

open access: yesJournal 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.
