Pore‐Scale Transition Behavior of Digital Carbonate Rock Dissolution During CO2 Geo‐Sequestration

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract Carbon dioxide‐rich brine formation during geological carbon sequestration induces calcite dissolution, governed by the physicochemical coupling of fluid flow, reactive transport, and pore structure evolution. Unveiling the mechanisms that control this dissolution, particularly under varying flow and structural conditions, is essential for ...

A ModEx Framework for Watershed Subsurface Investigation With Limited Geophysical Data Using Machine Learning and Hydrologic Modeling

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Subsurface heterogeneity influences watershed hydrology strongly but remains difficult to characterize at catchment scales with sparse and costly field data. Geophysical surveys such as electromagnetic induction (EMI) provide local spatial subsurface images yet scaling them to watershed scales and converting EMI‐derived resistivity into ...

Prediction method of coalbed methane enrichment area based on multi parameter fusion

open access: yesMeitan kexue jishu
Coalbed methane (CBM) is a kind of gas reservoir which mainly exists in coal reservoirs in adsorption state. The prediction of coalbed methane enrichment area by seismic exploration is an important method to reduce the exploration risk and improve the ...

Novelda Stone: widely used within the Spanish architectural heritage

open access: yesMateriales de Construccion, 2002
Novelda Stone is a calcareous rock, of the biocalcarenite type. It is extracted from the «Vinalopó Medio» area (Alicante, eastern Spain). Novelda stone is known as construction material from the 13th century.

Capturing soil moisture and salinity changes in flooded coastal forests using electrical resistivity and induced polarization

open access: yesVadose Zone Journal, Volume 25, Issue 1, January/February 2026.
Abstract Geophysical methods provide high‐resolution spatial measurements of physical quantities sensitive to changes in soil moisture and salinity and can be used to monitor soil hydrological responses to flooding. However, extracting quantitative hydrological information from geophysical data remains challenging.
