Mapping Soil Salinity Prediction Enhanced by Time‐Series Remote Sensing Features
Land Degradation &Development, EarlyView.ABSTRACT Gaining timely knowledge of soil salinity's spatiotemporal dynamics is crucial for accurate mapping. Through temporal span comparisons, this study systematically extracts and utilizes time‐series features (TSFs) derived from Sentinel‐2 and Landsat 8 NDVI and SAVI data (2019–2023) to enhance prediction accuracy. Three datasets were constructed:

Mean annual groundwater recharge depth in transboundary aquifers
, 2017 Mean annual groundwater recharge depth is calculating by dividing the long-term mean groundwater recharge, including man-made components (returnflows, induced recharge, artificial recharge), by surface area of the whole aquifer. Indicator is expressed as mm/yr.

Land Degradation &Development, EarlyView.ABSTRACT Afforestation in the desert–oasis ecotone induces soil desiccation and secondary salinization. However, the seasonal dynamics of soil water–heat–salt interactions across plantations of different stand ages in arid regions remain unclear. Here, we investigated the seasonal patterns and coupled relationships of soil water–heat–salt dynamics in ...

Limnology and Oceanography: Methods, EarlyView.Abstract Greenhouse gas (GHG) emissions from freshwater ecosystems contribute significantly to global carbon budgets, yet they remain poorly constrained due to limited high‐frequency measurements. We tested a low‐cost, high‐frequency GHG measurement system in a long‐term mesocosm experiment in Lemming, Denmark, over a 7‐month period, focusing on CO2 ...

Materials and Corrosion, EarlyView.This study examines corrosion of copper and cast iron as candidate canister materials for high‐level radioactive waste disposal in contact with bentonite suspension. The influence of three electrolyte compositions on corrosion behavior under repository‐relevant conditions is assessed.

Nature of Surface Microcracks on Phosphorus Micro‐Alloyed Copper
Materials and Corrosion, EarlyView.SSRT tests and microscopic characterization methods were used to study the effect of plastic deformation and environment on the formation of surface microcracks on Cu‐OFP. Results show that, while ambient conditions produced thousands of microcracks per mm2, exposure to sulfide water resulted in fewer microcracks with no evidence of crack growth ...

Near Surface Geophysics, EarlyView.Abstract Electrical resistivity tomography (ERT) has been shown to be effective for surveying and monitoring dams, due to the method's sensitivity to moisture content and relevant physical properties (e.g., porosity). Automated ERT systems, capable of time‐lapse monitoring, can be used to detect variations in ground conditions.
