High-resolution geodetic velocities reveal role of weak faults in deformation of Tibetan Plateau
Published: 2023-04-20
Subjects: Physical Sciences and Mathematics
Understanding the key mechanisms that control the tectonic deformation of the continents remains a fundamental challenge in geodynamics. We present a high-resolution geodetic velocity field of the Tibetan Plateau, which shows that a few major strike-slip fault systems separate regions of more uniformly distributed deformation. We suggest that focused strain on major fault systems is enabled by [...]
Comparative analysis of mass balance estimates since 1959 at Mittivakkat Gletsjer (SE Greenland)
Published: 2026-03-26
Subjects: Physical Sciences and Mathematics
Mittivakkat Gletsjer (MIT) has the longest glaciological surface mass balance (SMB) record of any peripheral glacier in Greenland. In this study, we utilize the glaciological SMB record, calibrate SMB from the Regional Atmospheric Climate Model (RACMO), and calculate geodetic mass balance (MB) to provide a multi-methodic assessment of trends in SMB. Glaciological SMB and modelled SMB correlate [...]
The rapid progress of climate change requires effective concepts for protecting people indoors
Published: 2025-06-30
Subjects: Life Sciences, Medicine and Health Sciences
According to the latest forecasts from the United Nations, it is highly likely that we will miss by a wide margin the 1.5 °C climate target set in the Paris Agreement in 2015. Rather, this planet has to prepare for a global temperature increase of 2.6 - 3.1 °C by 2100 and associated frequently occurring extreme weather events. It is therefore high time to design and technically equip the [...]
mineralML: Leveraging Machine Learning for Probabilistic Mineral Classification
Published: 2026-03-27
Subjects: Earth Sciences, Geochemistry, Geology, Physical Sciences and Mathematics, Probability, Statistical Methodology, Statistics and Probability, Volcanology
Characterizing phase assemblages in igneous rocks and the chemical variability within these phases is the fundamental basis of many petrological investigations. We present mineralML (mineral classification using Machine Learning), an open-source Python package that classifies common igneous minerals based on oxide chemical data, with prediction scores. mineralML employs a two-stage neural [...]
Quantifying the intensity of crystallographic preferred orientation (CPO): some practical considerations and recommended practices
Published: 2025-08-16
Subjects: Earth Sciences, Geology, Mineral Physics, Physical Sciences and Mathematics, Tectonics and Structure
Crystallographic preferred orientations (CPOs) commonly develop during the crystal-plastic deformation of rocks and minerals, and are widely used to infer strain intensity and geometry, reconstruct deformation conditions, and estimate mechanical anisotropy. Although CPO intensity is often quantified using scalar metrics that reduce the full orientation distribution to a single value, these [...]
Spectral seismic interferometry: Efficient monitoring of unbiased seismic velocity changes at high temporal resolution
Published: 2026-03-26
Subjects: Physical Sciences and Mathematics
Ambient noise based monitoring of subsurface velocity changes does not require the explicit retrieval of Green's functions by correlation. Velocity variations can directly be observed from the fluctuations in the spectrograms of ambient noise time series or their cross-spectra. This approach is more resource efficient than the conventional Green's function based monitoring and ideally suited for [...]
crstools 1.0.0: an R package for cartographic analyses
Published: 2026-03-11
Subjects: Earth Sciences, Ecology and Evolutionary Biology, Life Sciences, Physical Sciences and Mathematics
Spatial analyses are central to ecological studies, underpinning applications ranging from species distribution modelling to conservation planning and macroecological inference. However, most of these require translating processes occurring on a spherical surface into a planar map, inevitably introducing distortion biases. Projection choice can therefore influence both visual interpretation and [...]
Melt sustains pre-monsoon flow while groundwater drives the monsoon in the Nepal Himalayas
Published: 2026-03-15
Subjects: Physical Sciences and Mathematics
Himalayan water-security assessments often focus on glacier retreat, yet groundwater may supply much of river flow. We combine seismic observations from the Hi-CLIMB transect across Nepal (2002–2004) with gauged discharge, satellite precipitation, and glacier-cover inventories to resolve when streamflow is sustained by melt versus groundwater. Relative seismic velocity changes track hillslope [...]
Closure of Constraints in the Earth System: Biogeochemical Cycles and Planetary-Scale Biological Organisation
Published: 2026-04-06
Subjects: Earth Sciences, Life Sciences, Systems Biology
The concept of closure of constraints has been developed as a characterization of the distinctive causal regime at work in biological systems. Its extension to ecological systems has been attempted but faces persistent difficulties regarding the individuation of ecosystems and the scope of functional ascription. Meanwhile, the question of the biological character of the Earth system (variously [...]
Knowledge for ambitious, integrated, value-explicit and just collective actions towards global biodiversity targets
Published: 2026-04-16
Subjects: Biodiversity, Nature and Society Relations
Parties to the Convention on Biological Diversity (CBD) agreed upon goals and targets for biodiversity in the Kunming-Montreal Global Biodiversity Framework (GBF). The success of the GBF depends on the collective actions of the Parties, i.e. member states, to the CBD. Essential challenges in this context include ensuring that efforts across Parties are sufficient to collectively meet global [...]
Nearly three decades of laser altimetry reveal strong regional contrasts and glacier-driven ice losses in Greenland
Published: 2026-03-27
Subjects: Earth Sciences, Physical Sciences and Mathematics
The Greenland Ice Sheet, a major contributor to sea-level rise, loses mass through complex processes that are not fully understood. Laser altimetry provides direct and accurate measurements of ice sheet surface elevation. Here, we present the first continuous, laser altimetry-based annual reconstruction of Greenland Ice Sheet mass change from 1994 to 2020 at 1 km horizontal resolution. Our novel [...]
Open ocean biogeochemical impacts of extreme terrestrial precipitation
Published: 2025-09-24
Subjects: Oceanography and Atmospheric Sciences and Meteorology
Extreme events reshape ocean ecosystems with significant implications for nutrient and carbon cycling. Here, we demonstrate that flooding on land can be a significant driver of biogeochemical variability in the open ocean, even in relatively dry climates. Using satellite observations, in situ measurements, and Lagrangian particle tracking, we present evidence that freshwater discharge from [...]
Poor environmental conditions, food and water insecurity, neighborhood perceptions, and self-reported physical and mental health in four disadvantaged urban communities in Salvador, Brazil: a cross-sectional study.
Published: 2026-04-02
Subjects: Public Health
Emerging evidence suggests an association between environmental conditions and mental well-being. While the physical health impacts of environmental exposures such as contaminated drinking water or open sewers are well-documented with respect to the spread of infectious diseases, the mental health implications of these poor environmental conditions and exposures are less well understood, [...]
Carbon mineralization in CO2-seawater-basalt systems: Reactive transport dynamics and vesicular pore architecture controls
Published: 2026-03-06
Subjects: Earth Sciences, Environmental Sciences
Carbon mineralization in basaltic rocks offers a promising pathway for rapid, permanent CO2 storage, yet the fundamental controls on reactive transport, precipitation patterns, and permeability evolution under seawater conditions remain poorly constrained. This study integrates flow-through column experiments at 80°C with CO2-acidified seawater, geochemical modeling, and multi-scale pore imaging [...]
The Use of an Alum-Based Coagulant “Bucochem” for the Cleaning of Natural Water from Styrene/Divinylbenzene Microplastics
Published: 2026-03-27
Subjects: Other Life Sciences
The efficiency of an alum-based coagulant BUCOCHEM in removing styrene/divinylbenzene microplastic particles sized between 400 and 500 µm from water has been investigated. It was found that the coagulant promotes better sedimentation and compaction of the plastic particles, ensuring the formation of a dense, more stable, and more easily removable sediment layer. 0.1 wt % of the coagulant leads to [...]
