Explaining land subsidence variation along the north coast of Java for Semarang and Pekalongan, Indonesia
Published: 2024-03-31
Subjects: Physical Sciences and Mathematics
This study investigates the significant land subsidence in the cities of Semarang and Pekalongan on the north coast of Java. High land subsidence rates of several cm up to dm per year have being reported, directly contributing to relative sea-level rise. This research uses PS-InSAR data to analyze the spatial and temporal variations in subsidence and identify its causes, which are expected to be [...]
Global environmental plastics dispersal under OECD policy scenarios towards 2060
Published: 2024-03-30
Subjects: Physical Sciences and Mathematics
Plastics occupy a central role in the global economy, yet cause significant damage to ecosystems and human health. Recent studies and OECD reports have provided comprehensive roadmaps to reduce the environmental impacts of plastics, based on coordinated global action to reduce plastic consumption and improve waste management and recycling. Leakage of mismanaged plastic waste to aquatic [...]
Assessing effects of agriculture value added, industry value added and imports value added percentage to GDP on CO2 emissions in Bangladesh: An ARDL and NARDL approach.
Published: 2024-03-28
Subjects: Environmental Sciences
The study aims to evaluate the impact of Bangladesh's agricultural and industrial sectors on CO2 emissions using advanced modeling techniques, namely autoregressive distributed lag (ARDL) and nonlinear autoregressive distributed lag (NARDL) models. Time-series data ranging from 1990 to 2022 are analyzed to ensure data stationarity, employing the augmented Dickey-Fuller (ADF) test. Subsequently, [...]
Numerical and physical instability of subglacial water flow
Published: 2024-03-28
Subjects: Physical Sciences and Mathematics
The sliding speed of glaciers depends strongly on the water pressure at the ice-sediment interface, which is controlled by the efficiency of water transport through a subglacial hydrological system. The least efficient component of the system is a `distributed' uniform sheet flow everywhere beneath the ice, whereas the `channelised' drainage through large, thermally eroded conduits is more [...]
Can spinodal decomposition occur during decompression-induced vesiculation of magma?
Published: 2024-03-28
Subjects: Physical Sciences and Mathematics
Volcanic eruptions are driven by decompression-induced vesiculation of supersaturated volatile components in magma. The initial phase of this phenomenon has long been described as a phase of nucleation and growth. Recently, it was proposed that spinodal decomposition (an energetically spontaneous phase separation that does not require the formation of a distinct interface) may occur during [...]
Forecasting Urban Water Escherichia coli Contamination Using Machine Learning Models
Published: 2024-03-26
Subjects: Microbiology
The state of Indiana ranks first in the nation for water recreation impairments due to contaminated waterways. According to U.S. Environmental Protection Agency, 73% of rivers and streams and 23% of lakes and reservoirs have recreational use impairments like swimming, fishing and boating. Increased density of urban population and agricultural activities are some of the key contributors to run-off [...]
The Equator Project Research School and Mentoring Network: evaluated interventions to improve equity in geoscience research
Published: 2024-03-26
Subjects: Education, Physical Sciences and Mathematics
There is a well-documented racial and ethnic diversity crisis in Geography, Earth and Environmental Sciences (GEES) subjects in the Global North that leads to inequities in who does environmental research. The Equator project set out to increase participation and retention of UK-domiciled Black, Asian and minority ethnic students in GEES research by developing evidence-based, ring-fenced, fully [...]
A consistent terminology to communicate ground-related uncertainty
Published: 2024-03-26
Subjects: Civil and Environmental Engineering, Earth Sciences, Environmental Sciences, Risk Analysis, Social and Behavioral Sciences, Statistics and Probability
Engineering geology is highly affected by uncertainty related to the geology, geotechnical parameters, models used and methods. While the technical aspects of ground-related uncertainty are increasingly investigated, the terminology to communicate uncertainty (i.e. phrases such as “it is very likely that”) has not yet been unified and experts use it however they see fit. The problem [...]
Navigating uncertainty and sensitivity analysis of future tropical cyclone risk estimates
Published: 2024-03-22
Subjects: Climate, Environmental Indicators and Impact Assessment
Future tropical cyclone risks will evolve depending on climate change and socio-economic development, entailing significant uncertainties. An uncertainty and sensitivity analysis of future tropical cyclone risks is thus vital for robust decision-making and model improvement. However, the outcomes of such uncertainty and sensitivity analyses are tied to the chosen model setup, warranting caution [...]
Relational representation: speaking with and not about Nature
Published: 2024-03-21
Subjects: Environmental Studies
The transnational movement to recognise the rights of Nature continues to fuel experimentation by a growing number of jurisdictions in legal form, content, powers, and governance arrangements. In this paper, we focus on the mechanisms through which Nature is represented in various ways. There is enormous diversity in representational arrangements, but there is no clarity on precisely who should [...]
Grüneisen parameter formalism in the study of the Earth's core formation: a sensitivity study
Published: 2024-03-21
Subjects: Condensed Matter Physics, Earth Sciences, Geochemistry, Geology, Mineral Physics, Other Earth Sciences, Planetary Geophysics and Seismology, Planetary Mineral Physics, Planetary Sciences
The Grüneisen parameter is an important parameter for the thermal state and evolution of the core, but its uncertainties and their implications are sometimes overlooked . Several formalisms using different parameters values have been used in different studies, making comparison between studies difficult. In this paper, we use previously published datasets to test the sensitivity of modeling the [...]
An inventory of phreatomagmatic volcanoes in the Trans-Mexican Volcanic Belt
Published: 2024-03-20
Subjects: Physical Sciences and Mathematics
The formation of phreatomagmatic volcanoes (PVs) usually involves small volumes of magma but also very violent eruptive activity. Along the Trans-Mexican Volcanic Belt (TMVB) the basic conditions that favor water-magma interaction are provided by the presence of frequent small-volume monogenetic volcanism and several inter-montane lacustrine basins. The TMVB is a Plio-Quaternary continental [...]
Sink of eddy energy by submesoscale sea surface temperature variability in a coupled regional model
Published: 2024-03-20
Subjects: Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics
Air-sea interaction impacts ocean energetics via modifications to the exchange of momentum and buoyancy. Prior work at the submesoscale has largely focused on mechanisms related to the eddy kinetic energy (EKE), such as the current feedback on stress, which generates negative wind work, or variations in sea surface temperature (SST) that modify surface winds. However, less is known about the [...]
Tracing Andean Origins: A Machine Learning Framework for Lead Isotopes
Published: 2024-03-19
Subjects: Physical Sciences and Mathematics
This study uses machine learning techniques to facilitate the geolocation of Andean lead isotopes, a novel approach in this geographical context. Two predictive models for latitude and longitude were developed based on the compilation of a database of the lead isotope ratios 206Pb/204Pb, 207Pb/204Pb, and 208Pb/204Pb from multiple Andean provinces. These models were cross-validated using [...]
