Fault Friction, Plate Rheology, and Mantle Torques From a Global Dynamic Model of Neotectonics

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Improvements in software, parallel computing, global data sets, and laboratory flow‐laws help to develop the global Earth5 thin‐shell finite‐element model of Bird et al. (2008, https://doi.org/10.1029/2007jb005460) into a benchmark study. All experiments confirm that modeled faults (other than megathrusts) have low effective friction of 0.085 ±

Testing the Limits of Provenance Analysis From Basaltic Fluvial Sediment Near Sandvatn, Iceland, as a Mars Analog

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Detrital sediments that accumulate downstream and are preserved in sedimentary rocks can allow characterization of geologic formations that are inaccessible for spatial or temporal reasons. However, mixing, sorting, and alteration of sediment during transport may complicate reconstruction of protolith characteristics.

Monitoring Groundwater Pumping Using Time‐Lapse Tomography From Ambient Seismic Noise

open access: yesWater Resources Research, Volume 62, Issue 4, April 2026.
Abstract Management of water resources will be of critical importance as the effects of climate change accelerate. This implies the need to monitor water resources with high spatial and temporal resolution. One way to meet this need could be passive seismic methods using ambient seismic noise. In this study, we present a novel approach using time‐lapse

Seismic Stratigraphy of the Peruvian Forearc Drifts from 3° to 7°S: Identification and Influence of Lower Layers of the Humboldt Current System

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract The seafloor morphology and subsurface geometry of a late Neogene contourite drift located along the Peru margin is documented for the first time using multibeam bathymetry, two‐dimensional and three‐dimensional seismic data. Along the margin several submarine canyons incise the shelf and slope.

Cultivation‐Based Detection of a Novel High‐GC Nitrospira Derived From the Argentinian Copahue Volcano Area

open access: yesEnvironmental Microbiology, Volume 28, Issue 4, April 2026.
In this cultivation‐based study, two novel moderately thermophilic Nitrospira enrichments were obtained from the geothermal field Las Máquinas in the Neuquén Province, Argentina. Both nitrite oxidizers, belonging to lineage V or the novel taxonomic lineage VIII, contain quorum‐sensing genes and a high genome GC content of 60.6% and 69.4%.

Impact of Fire and Heat Stress on Soil Microorganisms: A Review of Community Changes, Molecular Responses and Plant‐Beneficial Roles

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This work reviewed the direct and indirect effects of fires on microbial communities and the resilience strategies microbes use to withstand high temperatures . ABSTRACT Fire, whether occurring on the surface or underground, significantly influences soil microbial dynamics by reshaping community composition, functional diversity and overall soil and ...
