In this context, <em>Shewanella oneidensis</em> MR-1 was chosen as a model microorganism to investigate the feasibility of using inexpensive and abundant talc as a magnesium source for the microbial mineralization of struvite. The results showed that talc was able to provide magnesium ions for strain MR-1 to induce struvite mineralization, producing prismatic struvite with a purity of up to 78.42 mass%. With increasing ball-milling times from 0 to 90 min, the struvite purity gradually increased from 15.08 mass% to 51.36 mass%, and Mg transformation efficiency of talc increased from 3.95 % to 20.68 %. These findings indicate that mechanical activation can significantly improve the reactivity of talc in the microbial mineralization process. With increasing talc additions from 0.2 g/L to 2.0 g/L, the struvite purity gradually decreased from 78.42 mass% to 41.68 mass%, and Mg transformation efficiency of talc ranged from 17.54 % to 28.02 %. These findings revealed that excess talc could not be effectively converted into struvite and that excess talc also reduced struvite purity. Dissolution experiments revealed that organic matter such as amino acids in the culture medium and ammonium ions produced by strain MR-1, promoted the dissolution of magnesium ions in talc. This study deepens the understanding of microbial-mineral interactions and provides an economically feasible pathway for the removal and recovery of organic nitrogen and organophosphorus in eutrophic waters.</div></div>","PeriodicalId":245,"journal":{"name":"Applied Clay Science","volume":"276 ","pages":"Article 107927"},"PeriodicalIF":5.3,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144534184","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}

But the instrumental record is short and provides a limited dynamic range with which to test assumptions about H₂ cycling. Here, we compare twentieth century H₂ levels reconstructed from polar firn air to the output from a historical run of the Geophysical Fluid Dynamics Laboratory Atmospheric Model 4.1 (GFDL-AM4.1). Simulated H₂ exhibits reasonable agreement with the reconstruction. The twentieth century increase in H₂ levels is consistent with rising atmospheric methane levels and changing emissions from fossil fuel combustion. However, the model fails to capture the reconstructed reversal in the interpolar H₂ gradient between 1960 and 1990. We invert an 8-box model of the atmosphere to show that the reversal in the interpolar difference requires a large increase (decrease) in the simulated NH (SH) net source of H₂ peaking circa 1980. Revisions to our estimates of historical biomass burning emissions, photochemical production, and/or anthropogenic emissions could help resolve the discrepancy. Our optimization also implies a 15% increase in the strength of the soil sink in the NH mid to high-latitudes from 1970 to 2000, which is qualitatively consistent with expectations based on changing soil moisture and temperature. We also show that smaller adjustments to the H₂ budget would be needed to explain the reversal in the interpolar gradient if the H₂ deposition lifetime were shorter than commonly accepted. A shorter lifetime may be supported by recently identified geological sources of H₂.</p>","PeriodicalId":15986,"journal":{"name":"Journal of Geophysical Research: Atmospheres","volume":"130 13","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144536964","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}

During its initial calibration and validation phase (cal/val), SWOT conducted daily observations for 3 months providing unparalleled insights into the high variability of water levels at daily and kilometer scales, far surpassing capabilities of past and current altimeters. Here, this novel data set is evaluated in the hyper-tidal coastal-estuarine environment of the Bristol Channel-Severn Estuary. SWOT total water levels (TWLs) are assessed against data from a network of in-situ water level gauges (WLGs) and compared to the performance of the CryoSat-2 satellite altimeter. In this region, CryoSat-2 water levels agree well with WLG data, with a Root Mean Square Difference (RMSD) of 0.17 m. Comparisons of SWOT Level 3 low rate 2 km (L3) total water level with WLG data reveal constant offsets that scale with water elevation, attributed to the spatial difference between the measurements. Once corrected, L3 TWLs achieve RMSDs ranging from 0.059 to 0.150 m against individual gauges. Overall, the scaled L3 data exhibit an RMSD of 0.137 m, a regression slope of 0.99 and offset +0.044 m, demonstrating that SWOT delivers high-quality water level data in these dynamic and challenging environments. SWOT's altimetry images reveal complex, changing spatial patterns across the Land-Ocean Aquatic Continuum. These daily measurements resolve fast-changing processes, such as river discharge events, sandbank movements and storm surges — phenomena missed by the 21-day cycle of the SWOT science phase.</p>","PeriodicalId":54286,"journal":{"name":"Earth and Space Science","volume":"12 7","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1029/2024EA004104","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144537012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This relationship maintains a quasi-constant floor of ∼2.8 nT in SW B carried to the heliosphere by the SSW during the last ∼60 years, in contrast to the contributions of CMEs and HSSs to SW B that exhibit the 11-year variation of the large-scale (LS) dynamo. We propose the SSW is not a by-product of the LS-dynamo, as currently thought, but rather results from a small-scale dynamo that continually replenishes intranetwork flux that undergoes flux cancellation reconnection, to supply a fixed amount of open flux to the heliosphere.

Yet, the underlying dynamic mechanisms remains unclear. Here in this study, causality analysis was first conducted based on satellite and reanalysis data, which suggested that local winds rather than the upstream Kuroshio transport or the surface cooling play a primary role. Numerical model experiments further confirmed this point. In winter, the downwelling-favorable northerly wind reduces the sea level in the middle shelf through Ekman pumping; whereas, the high sea level at the shelf break, due to the northward-flowing Kuroshio, slightly increases. The enhanced shoreward barotropic gradient force then pushes Kuroshio to the shelf once it loses the support of the island. Consequently, a horizontal difference in temperature, thus density, is formed by the intrusive warm water, which is further amplified by the differential air-sea heat flux. The resultant baroclinic effect regulates the path of intrusive water, forming an anticyclonic loop. In summer, the absence of these two effects results in a much weaker upper-layer Kuroshio intrusion. In autumn and spring, the differential cooling effects are negligible, and the barotropic effect of episodic northerly winds alone can induce a weak intrusion, but the anticyclonic loop is absent. In short, local winds directly trigger the upper-layer Kuroshio intrusion northeast of the Taiwan Island; other effects, such as differential cooling, are secondary.</p>","PeriodicalId":54340,"journal":{"name":"Journal of Geophysical Research-Oceans","volume":"130 7","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144536849","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}
