Contrasting sensitivity of weathering proxies to Quaternary climate and sea-level fluctuations on the southern slope of the South China Sea
<p>Tropical marginal seas host important sedimentary archives that may be exploited to reveal past changes in continental erosion, chemical weathering, and ocean dynamics. However, these records can be challenging to interpret due to the complex interactions between climate and particulate transport across ocean margins. For the southern South China Sea over the last 90 kyr, we observe a contrasting temporal relationship between the deposition of clay minerals and magnetic minerals, which were associated with two different hydrodynamic modes. Fine-grained clay minerals can be carried in suspension by ocean currents, leading to a rapid response to regional climate-driven inputs. In contrast, changes in magnetic mineralogy were linked to glacial-interglacial sea-level variability, from which we infer a control by bedload transport and resuspension. Overall, this study indicates that the transfer pathways and mechanisms imparted by varying hydrodynamic conditions exert a substantial influence on the distribution of terrigenous material in continental margin sediments.</p>

Stable Water Isotopes in Fresh Snow Along 2 Slopes in the canton of Grisons/Graubünden, Switzerland: the "Chruez", Praettigau and Eastward ascent to the Vilan Peak
<p>This bachelor thesis concerned itself with the composition of <span class="math-tex">\(\delta\)</span>2H (or deuterium), <span class="math-tex">\(\delta\)</span>18O and <span class="math-tex">\(\delta\)</span>17O in fresh snow. Stable water isotopes have been proven to be useful tracers for hydrological processes, such as air mass sources of regional precipitation or the residence time of snowmelt in a catchment (Beria et al., 2018). Whereas different isotopic compositions of precipitation in the form of rain is well documented for different environments in networks such as the NISOT (The Swiss National Network for the Observation of Isotopes in the Water Cycle), the same knowledge about snow is more limited due to the influences of different isotope fractionation processes and lack of onsite snow accumulation and melt observation (Cooper, 1998; Michelon et al., 2018). The aim of this thesis was therefore to analyse and characterize the spatial variability of <span class="math-tex">\(\delta\)</span>2H, <span class="math-tex">\(\delta\)</span>18O and <span class="math-tex">\(\delta\)</span>17O in freshly fallen snow. This was done by sampling fresh snow on six different snowfall events in the month of March over an elevation gradient of 1000m along the southside slope of the mountain Chruez. 2H throughout four sampling days had <span class="math-tex">\(\delta\)</span>-values ranging from −50‰ to −70‰, with two days being more depleted in 2H, showing <span class="math-tex">\(\delta\)</span>-values from −80‰ down to −160‰. <span class="math-tex">\(\delta\)</span>18O showed the same pattern where of six, four days showed similar -values ranging from −8‰ to −12‰ and two days with a stronger depletion of the isotope with <span class="math-tex">\(\delta\)</span>-values ranging from −14‰ to −20‰. It is known that the enrichment of <span class="math-tex">\(\delta\)</span>17O in a water molecule is about half of <span class="math-tex">\(\delta\)</span>18O, which was also seen in the results of this thesis (Nyamgerel et.al, 2021).</p> <p>In this thesis, two out of six sampling days were examined with statistically significant positive altitude gradients of 0.19‰/100m and 0.64‰/100m for <span class="math-tex">\(\delta\)</span>18O. Additionally, on one of the six sampling days, a statistically significant negative altitude gradient of −0.15‰/100m was observed. The altitude gradients for <span class="math-tex">\(\delta\)</span>17O were about half of <span class="math-tex">\(\delta\)</span>18O. Two statistically significant positive and one negative altitude gradients for <span class="math-tex">\(\delta\)</span>2H were observed during the same days with lapse rates of 1.7‰/100m, 5.5‰/100m and −1.25‰/100m. Having both positive and negative altitude gradients was attributed to the varying amounts of solar radiation and wind direction during different sampling days. However, further research must be done in order to make a valid statement, since additional factors such as water vapor pressure, turbulent fluxes in the air and relative humidity strongly affect fractionation of stable water isotopes.</p> <p>The aim of this work is to characterize and analyze the elevation effect of water isotopologues in fresh snow at Vilan. By analyzing fresh snow, the influence of fractionation processes, after the precipitation event can be minimized and helps the understanding of snow-melt water transformation. For this purpose, a total of five fresh snow events in March and April 2021 were analyzed. Samples were taken from the eastern slope of Vilan between 1100 m a.s.l. and 2300 m a.s.l. and were collected at 100-meter elevation intervals. The altitude effect was determined with a linear regression. The analysis shows that the altitude has only a small effect on the d-values of the new snow, because for the <span class="math-tex">\(\delta\)</span>18O only one snow event shows a statistically significant altitude effect. For the <span class="math-tex">\(\delta\)</span>2H, it is their two. The statistically significant new snow events show an elevation gradient of + 0.155 ‰ <span class="math-tex">\(\delta\)</span>18O/100 m and + 1.211 ‰ <span class="math-tex">\(\delta\)</span>2H/100 m and + 0.677 ‰ <span class="math-tex">\(\delta\)</span>2H/100 m, respectively. The observed positive gradients can be explained by four effects. First, a lee effect is likely due to the prevailing weather conditions. Second, the top snow layer accumulates heavy isotopologues with increasing time (time effect). Third, an inverse height effect can be observed when water vapor of different origins mixes. Fourth, the amount of precipitation (quantity effect) can have an impact on isotopic composition. The work shows that further research in the analysis of water isotopes in fresh snow is necessary to better identify and quantify possible influencing parameters.</p> <p> </p> <p> </p>
Rapid Repair of Cracks on the Embankment Slopes Using Bio-Cement
<p>This research explored the feasibility of using Microbially Induced Carbonate Precipitation (MICP) to improve fine-grained soil mechanical properties, seal the soil cracks, and assess the improvement of MICP on slope stability. The conducted research tasks include (1) direct shear tests to investigate the mechanical behavior and biogeochemical reactions of low-plasticity silt treated by MICP, (2) cyclic wetting-drying tests to assess the feasibility of using MICP to seal and waterproof the soil cracks, and (3) SLOPE/W modeling of a slope treated by MICP. Direct shear tests were used to evaluate the shear responses of the low-plasticity silt under different overburden pressures (12, 25, and 35 kPa) and different bio-cement treatments. A series of cyclic wetting-drying tests were used to assess the effectiveness of MICP treatment on healing soil cracks. Crack lengths, area, width, and area percentage were measured and compared before and after the MICP treatment. SLOPE/W analysis was performed to assess the factor of safety of a slope under MICP treatment. The direct shear tests results show that the peak shear strengths increased by an average of 30% from the untreated to the MICP-treated soil samples. The wetting-drying cycle tests results show that MICP treatment can heal desiccation cracks, reducing crack length, crack width, and crack area. The results of the SLOPE/W modeling show that the MICP treatment had a positive effect on the improvement of slope stability, but more field tests are needed for optimizing the treatment solutions and procedures and assessing the long-term effect and ecological impacts.</p>
