Abstract Climatic changes have played an important role in societal reorganizations. Particularly, the late 16th and early 17th century coincided with severely cold condition, extremely weak summer monsoon widespread population decline China. Here we present new speleothem oxygen isotope records across North South China, which concert historical documents, allow us to characterize “Late Ming Weak Monsoon Periods” (LMWMP) at unprecedented annual temporal resolution. Our analysis suggests that...
Anthropogenic activities and climate change have increased the stress on world’s estuaries over past decades. Limited knowledge exists about how estuarine receding responds to human interference, particularly geomorphic dynamics of channels sandbars. Here, we evaluate topographic evolution upper Yangtze River Estuary (YRE), largest branch reach with frequently shifting sandbars, from 1994 2019. Our results show that a net channel erosion 9.59 × 108 m3 occurred in YRE, equivalent an annual...
Using 137Cs and 210Pb dating multi-proxy evidence from a 41-cm sediment core Bosten Lake in China, the responses of grain size to environmental changes were reconstructed over past 150 years. After end Little Ice Age, climate region became warmer drier, lake water level decreased. The results indicated that lowest storage periods occurred at approximately 1920-1930 AD. Decreases Siberian High intensity vapour transport Indian Ocean during this period led reduction supply, which resulted...
Submarine groundwater discharge (SGD), including both land-based fresh that enters the ocean from coastal aquifers as well recirculated seawater is continuously recharged and discharged on seabed, has been considered an important component of global water biogenic element (e.g., nitrogen, phosphorus, silicon carbon) sources a significant pathway for material exchange at land-sea interface ecosystems. Some researchers reported SGD associated nutrient additions to waters have caused unwanted...
<p>A short (50-cm-long) sediment core from Ebinur Lake in arid central Asia has been analyzed for various environmental proxies, including organic matter content, δ<sup>13</sup>C matter, magnetic susceptibility, heavy metal contents, and stable isotopic compositions of bulk carbonate (δ<sup>18</sup>O δ<sup>13</sup>C). The results reveal that the evolutionary stages inferred indicators have an asynchronous nature. If asynchrony periodic changes...
Karst water quality degradation has been a challenge for domestic and industrial supplies worldwide. To reveal the possible factors response karst degradation, Baotu spring system is studied as an representative example. In this study, hydrogeochemical investigation mathematical, statistical, geochemical modeling was conducted together to identify major hydrochemical processes involved in process. It found that normally fresh, neutral-to-slightly alkaline, with calcium magnesium predominant...
Objective: To explore the characteristics of college students' equity sensitivity, relationship between temperament, family social class and sensitivity. Method: 264 students which from different type universities were assessed with Equity Sensitivity Scale, The Formal Characteristics Behaviour Temperament Inventory (FCB-TI), Family Social Economic Status Questionnaire. Results Conclusion: sensitivity had significantly gender differences grade differences, in first was higher than that...
Fluorescent substances are used as good tracers in dissolved organic matter (DOM) to identify the source of DOM and its geochemical behavior a hydrological system. However, there few studies on karst aquifer Many parameters systems affect spectral information. A typical watershed Northern China was selected this research. Excitation-emission matrices (EEMs), parallel factor analysis (PARAFAC), hydrochemical data were applied reveal relationship between composition transformation fluorescent...
Spreading of the AgCuTi filler metal over a pure molybdenum substrate under high‐purity argon atmosphere was studied at elevated temperatures, within range 1283 ~ 1373 K. Real‐time in situ observations and quantitative measurements assisted by hot‐stage microscopy were used to analyze kinetics triple‐line movement. The state interface between resolidified alloy neighborhood triple line considered. empirical data indicate that wetting on features similar trend kinetics. equivalent radius...
The significance of CO2 emissions at the water–air interface from inland water bodies in global carbon cycle has been recognized and is being studied more more. Although it important to accurately assess emission flux a catchment, little research carried out investigate spatio-temporal variations view continuum. Here, we systematically compared differences control factors degassing across spring–river–lake continuum discharge area Baotuquan Spring July 2017, which typical temperate karst...
Existing seawalls along the eastern coast of China are increasingly becoming focus upgrade operations. Concerns arise regarding settling and stability built on soft clayey seabed during Pore water pressure (PWP) horizontal displacement accumulations induced by combined tide wave loadings observed in in-situ measurements underneath seawall. The measurement results show clear correlations between oscillations excess PWP variations tidal height. To reproduce quasi-static interaction behaviors...
Sustainability issues involving materials processing and manufacturing are still very poorly investigated. This is true in particular for non-energy parts of such systems. Thermodynamics approaches attract an increasing attention due to general applicability a clear potential include both quantity quality aspects resources utilization, process assessments metrics selection. One the main arguments justifying development thermodynamic sustainability that irreversibility does indicate level...
The identification of rock structure has a significant impact on the mechanical properties and seepage characteristics reservoir. In order to truly, accurately intuitively characterize pore rocks, thick limestone core samples in Baotu Spring basin were scanned by CT three-dimensional digital was constructed, finally display quantitative characterization realized. research shows that types this mass are mainly intergranular pores, dissolution pores few with an average radius 15.71 μm...
