Geochemical and granulometric fingerprints of 8200 years of westerly wind variability in inner‐fjord lake sediments from Svalbard

Boreas, EarlyView.
The Arctic is warming faster than any other region on Earth. As sea ice diminishes, the surface boundary conditions, such as roughness and air–sea coupling, change and open‐water fetch increases. This may enhance wind forcing on Arctic coasts. Lake sediments can record these changes through the deposition of wind‐blown grains and elements, offering ...

Processes and Patterns of Dolomite Precipitation in Aptian Pre‐Salt Deposits of Santos Basin, Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Aptian pre‐salt lacustrine carbonates represent the most significant oil exploration target along the South Atlantic margin. Dolomitization of the Santos Basin Barra Velha Formation (BVF) is critical for reservoir quality, yet its origin, patterns, and evolution remain poorly understood.

Multi‐Source Hydrogeological Investigation, Water Inflow Prediction, and Water–Mud Inrush Risk Zoning for a Strongly Karstified Limestone Tunnel: A Case Study of the Dongyang Tunnel

Engineering Reports, Volume 8, Issue 10, October 2026.
Multi‐source hydrogeological investigation identified widespread karst cavities and water‐bearing fractured zones along the Dongyang Tunnel. Comparative inflow prediction yielded a conservative design control value of 1557.61 m3/day, supporting section‐specific water–mud inrush zoning and targeted drilling, grouting, controlled drainage, and ...

Hydrochemistry of alluvial aquifer in the Cobra River sub-basin

Revista Brasileira de Engenharia Agrícola e Ambiental
The regional characteristics of waters from alluvial aquifers are different, since they depend on geology and climate. Also, there may be local variation in the quality of the available water when the water source is superficial (rivers and lakes) or is ...

Stable but Transient—Episodic Sensitivity in a Buffered German Karst Headwater Stream

Hydrological Processes, Volume 40, Issue 10, October 2026.
Baseline carbonate chemistry revealed coherent, degassing‐controlled patterns across the stream. Although warm low‐flow and rewetting periods temporarily increased system variability, carbonate buffering persisted (I). In addition, gas transfer and local hydromorphology decoupled CO2 evasion from pCO2 in a spring‐fed karst headwater stream (II ...
