Earthquake Swarm in Santorini - Greece: Recurrence Quantification Analysis and Investigation of Causal Relationship with Tidal Forces
Published: 2025-05-07
Subjects: Physical Sciences and Mathematics
In early 2025, an unusual earthquake swarm initiated in the sea area of the small uninhabited islet Anydros between Santorini and Amorgos islands in Greece. The unusual nature of this seismic activity and its subsequent seismic follow-up, motivated us to study its dynamical and statistical features. Namely, we investigated for a potential causal relationship between a simple model of [...]
The first seismo-volcanological observatory on Montserrat
Published: 2024-07-27
Subjects: Physical Sciences and Mathematics
The first seismo-volcanological observatory in the anglophone Caribbean was established on Montserrat in 1936, in response to a volcano-seismic crisis that began in in 1933. Staff at Montserrat’s agricultural office began routinely observing earthquake shocks in 1934. In 1936, following a scientific expedition dispatched by the Royal Society, an observatory was established at the Grove Botanical [...]
Climate Change and Ocean Acidification: Are We Just Treating The Symptoms?
Published: 2022-01-15
Subjects: Life Sciences
The human caused rise in atmospheric greenhouse gases has been seen as the driver of both climate change and ocean acidification. However recent peer reviewed papers show that, while GHG emissions are part of the problem, the primary driver of both climate change and ocean acidification is human caused ecological degradation. Curbing greenhouse gas emissions, to date, has been an abject failure [...]
VITAL-PATHS-FOOD: New Transformative Change Pathways for Tackling Climate, Human Development, and Biodiversity Loss and Incorporating Plural Perspectives on Justice and the Value of Nature.
Published: 2026-10-12
Subjects: Environmental Studies, Nature and Society Relations
The IPBES Transformative Change Assessment (2025) gives a central role to equity, justice, and the value of nature in facilitating sustainable transformations, by acting as a powerful deep leverage point that aligns sustainability transformations with the values and worldviews different communities hold. Scenarios and modelling studies offer a tool for examining ways of acting on these leverage [...]
Comparative Analysis of Microbial Community Composition in Tropical Aquatic Ecosystems
Published: 2025-05-06
Subjects: Microbiology
Aquatic ecosystems provide vital ecological services to global health through facilitating biogeochemical cycles, providing water for drinking & industrial usage, supporting fisheries, and preserving biodiversity. Critical elements such as climate change and growing anthropogenic pressures are causing changes in microbial communities, leading to far-reaching consequences for human health. [...]
The Role of Climate Services for Health: Theoretical Case Studies on Heat-Health Warning Systems in India
Published: 2025-05-06
Subjects: Public Health
Extreme heat is a growing public health concern across South Asia, with urban populations particularly vulnerable due to high population density, infrastructure gaps, and compounding socioeconomic risks. In this study, we assess the potential health benefits of Heat–Health Warning Systems (HHWS) as a Climate Service for Health (CSH) in urban India and explore their role in enhancing public health [...]
Characterizing compound physical and biogeochemical extremes in the California Current Large Marine Ecosystem
Published: 2025-05-06
Subjects: Oceanography and Atmospheric Sciences and Meteorology
Discrete environmental stressors, such as prolonged periods of extreme temperature or low oxygen, threaten the functioning of marine ecosystems. While considerable attention has been given to studying extremes occurring in isolation, our understanding of such events co-occurring in the water column–referred to as multi-stressor events or compound extremes–is still limited, despite their [...]
Gravity–topography regression across Antarctica: implications for isostatic regimes and subglacial crustal structure
Published: 2026-06-03
Subjects: Geophysics and Seismology
We investigate the relationship between Bouguer disturbance and equivalent topography across Antarctica using satellite gravity data, under the assumption that a linear relationship is expected at long wavelengths for Airy-type isostatic compensation. Equivalent topography ensures consistency across continental, marine, and ice-covered domains by expressing bathymetry and ice loads as [...]
Quantifying potential carbon dioxide removal via enhanced weathering using porewater from a field trial in Scotland
Published: 2025-04-08
Subjects: Engineering
Enhanced weathering (EW) is cited as a promising carbon dioxide removal (CDR) strategy, and is being rapidly commercialized. Rigorous monitoring, reporting and verification (MRV) are essential to ensure carbon claims are accurate and carbon credits are not mis-sold. MRV protocols incorporate multiple approaches, including soil and porewater sampling. This paper calculates potential CDR from [...]
Assessing the carbon footprint of a large international research program: study case of the BRIDGES kick-off meeting
Published: 2026-09-23
Subjects: Environmental Sciences
There is a rising concern in the academic community about the environmental impact of research activities. Carbon footprints are typically evaluated at the laboratory or institutional level, but there are lacking an evaluations at the level where research is actually performed, i.e. at the level of research projects. In this work, we focus on the french BRIDGES international research program as a [...]
Solution of the Bloch Equation Based on Spectral Diagonalization and Matrix Exponential Integration: Modeling of SSFP for SNMR
Published: 2025-05-10
Subjects: Earth Sciences, Geophysics and Seismology, Hydrology, Soil Science
We present a spectral-diagonalization-based matrix exponential integration (SD-MEI) algorithm for efficient and stable solutions of fully coupled Bloch equations in surface nuclear magnetic resonance (SNMR). Conventional explicit numerical methods exhibit cumulative discretization errors and escalating computational costs due to step-size dependence and finite precision limitations. SD-MEI [...]
Long-term trends and drivers of water color in Missouri reservoirs
Published: 2025-08-11
Subjects: Life Sciences, Terrestrial and Aquatic Ecology
Contrasting water quality trends are occurring within and across North America, with waterbodies experiencing increasing phytoplankton blooms, increasing dissolved organic matter, or both, while others are becoming clearer and bluer; dramatically changing water color. To assess the spatial and temporal variability in water color, we quantified trends in satellite-derived dominant wavelength (λd) [...]
Reframing natural organic matter research through compositional data analysis
Published: 2025-10-13
Subjects: Life Sciences
Compositional data (CoDa) are prevalent in environmental research. They represent parts of a whole, such as percentages, proportions, and relative or absolute abundance. They are arrays of positive data that convey relevant information in the ratios between their components. Standard statistical techniques developed for real random observations often yield spurious results and are therefore [...]

WASHed in stereotypes: A rigorous review of water-gender narratives in LMICs
Published: 2025-05-08
Subjects: Civil and Environmental Engineering
Over the past few decades, water programs have positioned women as primary beneficiaries, aiming to empower them through improved access and participation. In doing so, several gendered narratives have emerged, widely circulated but seldom interrogated, that continue to shape water, sanitation, and hygiene (WASH) policy and practice. Despite a growing body of literature on WASH and gender, there [...]
