Rock Physics of the Critical Zone: Models, Inversion, and Interpretation

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Rock physics models link geophysical measurements with subsurface petrophysical properties, such as porosity, mineral composition, and fluid saturation. While originally developed for hydrocarbon exploration, these models are increasingly applied in the near surface for quantitative interpretation of geophysical data.

Protracted High‐Grade Metamorphism and Slow Cooling in the Adirondacks Recalibrate Neoproterozoic Global Paleogeography

Tectonics, Volume 45, Issue 6, June 2026.
Abstract The assembly and breakup of the supercontinent Rodinia set the stage for Earth system evolution through the Neoproterozoic Era. Laurentia, the central craton in Rodinia, lacks well‐dated paleomagnetic poles between ca. 990 Ma and 780 Ma. In this study, we develop new U‐Pb petrochronology and thermochronology data sets from zircon, garnet ...

RS‐FloodXDepth: Enhancing Remote Sensing‐Derived Flood Extent and Estimating Flood Depth Using a Hydrologically Guided Region‐Growing Method and High‐Resolution DEMs

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Remote sensing imagery is widely utilized for mapping flood extents. However, sensor limitations and environmental conditions often reduce mapping capability. Factors such as obscuring clouds, terrain shadows, and dense tree canopies frequently lead to significant information gaps and omission errors, particularly in forests and urban areas ...

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.

Improved Constraints on Andean Glaciations From the Lake Titicaca Continental Drilling Record

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract Long sedimentary records from tropical lakes provide crucial archives for reconstructing the timing and extent of tropical alpine glaciations, yet robust chronologies beyond the radiocarbon limit (ca. 50 ka) remain scarce. Here, we refine the ca. 350 kyr chronology for Lake Titicaca (Peru‐Bolivia) using radiocarbon dating, optically stimulated

Hotspots on cold mountains: Hot flowers as pollinator refuges in mountain ecosystems

Functional Ecology, Volume 40, Issue 6, Page 1850-1861, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mountain environments constrain the activity of ectothermic insects. Yet, fine‐scale thermal refuges can buffer these thermal constraints, helping insects remain active in cold conditions.

Fats, Fire and Bronze Age Funerary Rites: Organic Residue Analysis of Wide Horizontal Rim Vessels From Burial Contexts in Northwest Portugal

Archaeometry, Volume 68, Issue 3, Page 298-310, June 2026.
ABSTRACT This study presents the first GC‐MS–based analyses of wide horizontal rim vessels with well‐defined funerary contexts, from Middle Bronze Age Portugal (Quinta do Amorim 2 and Pego). Organic residues from two vessels revealed ruminant fats and plant oils, alongside molecular markers of heat exposure.
