On the thermo-hydro-mechanical behaviour of Argillaceous hard soils - weak rocks

Saeed Tourchi

Published: 2023-01-31
Subjects: Engineering

Analysis and interpretation of the thermo-hydro-mechanical (THM) behaviour of argillaceous rocks is still among the most challenging of problems in geomechanical engineering. The comprehensive review of this wide variety of this class of materials has shown how different geotechnical parameters play various roles in the assessment of deep geological repository of high- and intermediate-level [...]

Revealing the hillslope response to earthquake legacy effect using time series InSAR

Nitheshnirmal Sadhasivam, Ling Chang, Hakan Tanyas

Published: 2023-01-31
Subjects: Geomorphology, Other Earth Sciences

Strong earthquakes are not only able to change the earth's surface processes by triggering a large population of coseismic landslides but also by influencing hillslope deformation rates in post-seismic periods. An increase in post-seismic hillslope deformation rates could also be linked to a change in post-seismic landslide hazard level and, thus, could be exploited to better assess post-seismic [...]

Size Resolved Aerosol Characterization and In-field Comparative Evaluation of TSI 1 nm SMPS at Lake Michigan Coastal Station

Megan B Christiansen, Charles O. Stanier, Dagen D. Hughes, et al.

Subjects: Atmospheric Sciences

The atmospheric particle size distribution was measured at a rural lakeshore site (Zion, IL 42.468 N, 87.810 W) during the Lake Michigan Ozone Study (LMOS 2017) in May and June 2017. The full aerosol size distribution was continuously measured by two scanning mobility particle sizers and an aerodynamic particle sizer in the range of 1.02 to 8671 nm (electrical mobility diameter). The Zion site, [...]

The nature of the proximal volcaniclastic materials from the 2021 eruption Fukutoku-Oka-no-Ba in the Izu-Bonin arc.

Kenta Yoshida, Yoshihiko Tamura, Tomoki Sato, et al.

Published: 2023-01-31
Subjects: Earth Sciences, Geology, Volcanology

Fukutoku-Oka-no-Ba is a submarine volcano located at 24°17.1′N/141°28.9′E in the Izu–Bonin–Mariana arc, and is one of the most active volcanoes in Japan. This volcano produced an explosive eruption in August 2021 that generated a large amount of volcaniclastic material, some of which drifted westward to Japan and the coastal area of East Asia as a pumice raft. The pumice clasts that drifted for [...]

Surface bacterioplankton community structure crossing the Antarctic Circumpolar Current Fronts

Matteo Selci, Angelina Cordone, Bernardo Barosa, et al.

Published: 2023-01-31
Subjects: Earth Sciences, Environmental Microbiology and Microbial Ecology Life Sciences

The Antarctic Circumpolar Current (ACC) is the major current in the Southern Ocean, isolating the warm stratified subtropical waters from the more homogeneous cold polar waters. The ACC flows from west to east around Antarctica and generates an overturning circulation by fostering deep-cold water upwelling and the formation of new water masses, affecting the Earth's heat balance and the global [...]

Climatic and cave setting influences on drip water fluorescent organic matter over an annual cycle in Northwestern Spain and implications for fluorescent laminations in stalagmites

Laura Endres, Céline Jacquin, Nikita Kaushal, et al.

Published: 2023-01-31
Subjects: Physical Sciences and Mathematics

Speleothem fluorescence may elucidate past vegetation dynamics, while microscale fluorescent laminations can provide annually resolved chronology. However, the origin of speleothem fluorescence and the mechanism responsible for the formation of micrometer scale fluorescent lamination in stalagmites, are not well constrained by monitoring studies. Here, we present results from a year-long monthly [...]

Quantifying Global-Warming Response of the Orographic Precipitation in a Typhoon Environment with Large-Eddy Simulations

Jianan Chen

Published: 2023-01-30
Subjects: Physical Sciences and Mathematics

The intense and moist winds in a tropical cyclone (TC) environment can produce strong mountain waves and substantially enhanced precipitation over complex terrain, yet few studies investigated how the orographic precipitation in a TC environment might respond to global warming. Here, we use large-eddy simulation to estimate the global warming-induced change in the precipitation over and near an [...]

Low Environmental Impact Remediation of Microplastics: Visible-Light Photocatalytic Degradation of PET Microplastics Using Bio-Inspired C,N-TiO2/SiO2 Photocatalysts

Maria Camila Ariza-tarazona, Cristina Siligardi, Hugo Alejandro Carreón-López, et al.

Published: 2023-01-30
Subjects: Engineering

Microplastics (MPs) are plastic particles of ≤5 mm with a ubiquitous presence in aquatic ecosystems. MPs harm marine life and can cause severe health problems for humans. Advanced oxidation processes (AOPs) that involve the in-situ generation of highly oxidant hydroxyl radicals can be an alternative to fight MPs pollution. Of all the AOPs, photocatalysis has been proven a clean technology to [...]

Numerical simulation of meteorite impact on basaltic lavas at Lonar Crater, India

Harshal Pohekar, Raymond Duraiswami, Satadru bhattacharya, et al.

Published: 2023-01-28
Subjects: Applied Mathematics, Astrophysics and Astronomy, Planetary Sciences

Lonar lake is a hypervelocity impact crater formed in a basaltic terrain of Deccan Traps in the state of Maharashtra, India. The crater has an approximate radius of 915 m and an average depth of about 137 m. Here we report the results of our numerical investigations aimed to elucidate the physical characteristics of incoming asteroid. For realistic simulation, we not only consider [...]

EUPollMap: The European atlas of contemporary pollen distribution maps derived from an integrated Kriging interpolation approach

Fabio Oriani, Manuel Chevalier, Grégoire Mariéthoz

Published: 2023-01-28
Subjects: Physical Sciences and Mathematics

Modern and fossil pollen data are widely used in paleoenvironmental research to characterise past environmental changes in a given location. However, their discrete and discontinuous nature can limit the inferences that can be made from them. In contrasts, deriving continuous spatial maps of the pollen presence from point-based datasets would enable more robust regional characterization of such [...]

Climate and health benefits of a transition from gas to electric cooking

Carlos F. Gould, M. Lorena Bejarano, Brandon de la Cuesta, et al.

Subjects: Environmental Public Health, Environmental Studies

Household electrification is thought to be an important part of a carbon neutral future, and could also have additional benefits to adopting households such as improved air quality. However, the effectiveness of specific electrification policies in reducing total emissions and boosting household livelihoods remains a crucial open question in both developed and developing countries. We [...]

Leaving a plastic legacy: current and future scenarios for mismanaged plastic waste in rivers

Bjorn Nyberg, Peter T Harris, Ian Kane, et al.

Published: 2023-01-26
Subjects: Earth Sciences, Environmental Sciences

Mismanaged plastic waste (MPW) entering the riverine environment is concerning, given that most plastic pollution never reaches the oceans, and it has a severe negative impact on terrestrial ecosystems. However, significant knowledge gaps on the storage and remobilization of MPW within different rivers over varying timescales remain. Here we analyze the exposure of river systems to MPW to better [...]

SEDucate: Sedimentary Log Exercises for an Active Learning Environment

Published: 2023-01-26
Subjects: Education

Active learning in education has been shown to improve a students’ learning experience in higher education by focusing on a student-centered learning environment; however, development of realistic activities that replicate the complexity of real-world examples without being too complex for the novice learner is often challenging. Here we present SEDucate, a GIS plugin to build realistic [...]

Land use change as an anthropogenic driver of mercury pollution

Aryeh Feinberg, Martin Jiskra, Pasquale Borrelli, et al.

Published: 2023-01-24
Subjects: Atmospheric Sciences, Biogeochemistry, Earth Sciences, Environmental Sciences

Mercury (Hg) released by anthropogenic activities can bioaccumulate to neurotoxic levels in commonly consumed fish. Global soils are a global long-term storage for atmospheric Hg taken up by vegetation, thereby decreasing the Hg burden to oceans and eventually fish. Anthropogenic activities like deforestation reduce the capacity of the terrestrial Hg sink and enhance the release of Hg from soils [...]
