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

Water 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

A Formation Inversion Algorithm Based on Collaborative Fuzzy Gradient Neural Dynamics for Natural Gamma Logging While Drilling

CAAI Transactions on Intelligence Technology, Volume 11, Issue 2, Page 498-513, April 2026.
ABSTRACT A formation inversion algorithm with real‐time performance and accuracy is crucial for natural gamma logging while drilling (LWD). However, traditional inversion algorithms are often limited by high computational resource consumption and insufficient accuracy.

Diversity, Distribution and Postglacial History of Native Pinus sylvestris Forests in the Iberian Peninsula

Journal of Biogeography, Volume 53, Issue 4, April 2026.
ABSTRACT Aim Pinus sylvestris is the most widely distributed Pinus species in the world, highlighting its ecological, economic and socio‐cultural importance. The Iberian Peninsula marks its south‐western distribution limit, whose extent has been significantly reduced since the Mid‐Holocene. In this study, we investigated the current diversity of native

The emerging use of magnetic resonance imaging to study river bed dynamics [PDF]

, 2015
The characterization of surface and sub-surface sedimentology has long been of interest to gravel-bed river researchers. The determination of surface structure is important as it exerts control over bed roughness, near-bed hydraulics and particle ...

Depositional Facies, Sequence Stratigraphy, and Diagenesis of Lower Cretaceous Carbonate Reservoir, Southern Iraq: Implications for Petroleum Exploration

Journal of Petroleum Geology, Volume 49, Issue 2, Page 312-345, April 2026.
ABSTRACT The Lower Cretaceous Yamama Formation of southern Iraq represents a key carbonate reservoir within Iraq and the Middle East, yet its complex depositional facies architecture and diagenetic alterations present challenges for predicting reservoir quality.

Growth and reworking of freshwater microbially‐mediated carbonates in wind‐stressed lake margins (Lago Sarmiento, Southern Patagonia)

Sedimentology, Volume 73, Issue 3, Page 706-741, April 2026.
ABSTRACT Understanding the biotic and abiotic influences on the deposition and diagenesis of recent microbial carbonates is crucial for addressing the environmental and ecological significance of ancient organosedimentary structures. This study investigates these factors and their expression in the microstructure of Holocene tufa thrombolites from a ...

Pre-impoundment Limnological Study of the Strawberry River in Northeastern Arkansas [PDF]

, 1971
A study of pre-impoundment limnological characteristics of the Strawberry River was made from August, 1967 to June, 1968. Two collecting stations were established, one upstream which would not be inundated and a lower station which would be inundated ...
