The mineralogical phase changes, observed seismically as semi-discontinuous features, act as a semi-permeable barrier to thermochemical flux between the upper and lower mantle. They partly control global mantle circulation patterns. However, understanding regional-scale convection processes relies on high-quality seismic measurements with improvements in observational approaches in terms of coverage and resolution. Here, we perform a comprehensive analysis of the MTZ discontinuities using new large global data sets of ScS reverberations. The data sets are compiled and processed using data-driven and machine learning methodologies, highlighting the prospective capacity of automated approaches for rapid data analysis. Our maps reveal significant topography variations in the 410 and 660 km discontinuity depths, and hence MTZ thickness, and provide complementary spatial geometry to existing MTZ maps. These results are consistent with first order correlation of MTZ thickness with seismic wavespeed, and further indicate additional smaller scale lateral variation in topography across all regions of data coverage. We integrate our observations with mineralogical modeling to derive new thermal and compositional models of the MTZ. Our models display a correlation between locations of recent subduction and basalt accumulation, and between hotspots and regions of high temperature. Both temperature and composition are dominated by short-length scale patterns in their variability, indicating ubiquitous and persistent heterogeneities within the MTZ. Together, these observations evidence widespread and long-term stagnation of material at and within the MTZ.</p>","PeriodicalId":15864,"journal":{"name":"Journal of Geophysical Research: Solid Earth","volume":"130 10","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145261598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The specific focus is on how the driving process affects the lateral and vertical deformations of the surrounding soft soil, as well as the interaction with neighboring columns. Different column configurations, spacing, and installation sequences were investigated. After evaluation and quantification of the deformation patterns, a methodology is proposed to study the extent of displacements caused by the tube's driving. Results showed that an increase in the spacing between columns reduced the influence of the tube's driving.

Increasing the number of GECs from three to four elements further reduced the displacements magnitude in the region adjacent to the first column installed.</div></div>","PeriodicalId":55096,"journal":{"name":"Geotextiles and Geomembranes","volume":"54 1","pages":"Pages 67-84"},"PeriodicalIF":6.2,"publicationDate":"2025-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145267358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To study this, we created a new magnetic local time dependent high-latitude Pc5 ULF wave index using magnetic field measurements from high latitude magnetometers obtained from SuperMAG. Our findings indicate that the impact angle of an IP shock does not determine the location of the peak Pc5 power. However, we find that frontal shocks drive stronger wave power than inclined shocks. Shock speed and dynamic pressure ratio correlate moderately with the peak Pc5 power. During 61% of the studied foreshock transients, we observe a clear Pc5 response, that is, the wave power increased significantly. The distribution of Pc5 power is consistent with the propagation direction of the transients. The results suggest that the size of the foreshock transient and the solar wind speed may affect the observed Pc5 wave response.

A broad diversity of IMF and local time dependence of aurora occurrence is observed across Mars' crustal magnetic fields. The polarity of a given crustal field determines whether its field lines preferentially magnetically connect to dayside ionospheric or nightside magnetotail electron sources in the post-dusk or pre-dawn sectors. We thus establish a “source preference metric”, that is, the excess likelihood of aurora when likely magnetically connected to the nightside versus dayside. A wide range of source preferences are observed across the crustal field features, with some showing higher occurrence for night sources, day sources, or neither, often differently when in the post-dusk or pre-dawn sectors. A generally stronger nightside source preference is found for radially inward crustal fields in the predawn sector, and for weaker outward crustal fields in the post-dusk sector.

Therefore, this study presents a more effective method for estimating secondary dune density by utilizing Google Earth images and the YOLOv8s algorithm. This study utilizes Google Earth images from the hinterland of the Taklimakan Desert to construct a secondary dune identification dataset.

The research results indicate that the model achieved an average precision (AP50) of 63.58 % for secondary dune identification, outperforming other baseline algorithms. Furthermore, the dune identification model successfully identified a total of 18,208 secondary dunes within the verification area. The model demonstrated a higher predictive capability for secondary dune densities in the Taklimakan Desert hinterland, with a coefficient of determination (<em>R²</em>) of 0.89 between estimated and observed values. The mean absolute error (<em>MAE</em>) was 20.94 km⁻², and the root mean square error (<em>RMSE</em>) was 25.04 km⁻².

As viable options for the large‐scale removal of nitrates from groundwater remain elusive, greater emphasis has been placed on stakeholder‐based integrative approaches, yet few have been developed, and fewer evaluated for their effectiveness. The Central Valley in California is one of the most important intensive agricultural regions globally, where such a stakeholder‐based process (CV‐SALTS) has been initiated, and which is poised to serve as a model for controlling nitrate contamination elsewhere. Based on the Groundwater Ambient Monitoring and Assessment Program data for the 2000–2023 period, we develop a new data sufficiency metric, quantify the uncertainties associated with establishing nitrate concentrations and their changes in space and time, the impact of Confined Animal Feeding Operations (CAFOs), seasonal variability and drought on nitrate levels, and how they are addressed through CV‐SALTS policies. Our findings suggest that there remain substantial uncertainties associated with where nitrate concentrations are above safe levels, but that they predominantly intersect with environmental justice communities. Severe drought conditions and the proximity of CAFOS significantly elevated nitrate concentrations, but had previously not been sufficiently monitored or considered. A new data sufficiency metric based on nitrate variability, maximum contaminant level exceedance, and observation density can support stakeholder processes in prioritizing areas for additional monitoring and risk reduction.
