A generalized additive mixed-effect modeling approach for characterizing Sentinel-2 surface reflectances of visible light from Torch Lake in Antrim County, Michigan, 2019-2025
Published: 2025-11-18
Subjects: Applied Statistics, Earth Sciences, Environmental Monitoring, Hydrology, Longitudinal Data Analysis and Time Series, Statistical Methodology, Statistics and Probability
A generalized additive model (GAM) and three generalized additive mixed-effect models (GAMMs) were developed and compared to describe variations of surface reflectances of visible light from Torch Lake in the blue, green, and red bands from Sentinel 2 satellite imagery. All models included fixed effects associated with water-depth intervals, satellite orbits, trend, and smooth effects associated [...]
Lithological heterogeneity controls high-temperature ductile deformation and late melt infiltration in moderately-magmatic OCCs
Published: 2025-11-18
Subjects: Earth Sciences, Geology, Tectonics and Structure
Oceanic core complexes (OCCs) are a fundamental component of slow-to-ultraslow spreading mid-ocean ridges, yet the processes that control OCC formation and evolution are poorly understood especially with respect to their high-temperature lithospheric roots. We present detailed analyses of high-temperature ductile deformation preserved in drill-core from IODP Hole U1601C, on the Atlantis Massif [...]
Changes in Oceanic Carbon Storage due to Anthropogenic Carbon Input over the Past Three Decades
Published: 2025-11-18
Subjects: Climate, Oceanography
While the ocean is known to be an important sink for anthropogenic CO2 emissions, assessing trends in ocean’s uptake and storage of atmospheric CO2 is complicated because changes in the ocean dissolvedinorganic carbon (DIC) concentrations due to natural ocean circulation patterns and flux of anthropogenic CO2 need to be disentangled. In this study, we analyze the interannual and decadal changes [...]
Impact of weather and season on stored water contamination and infant diarrhea in climate-vulnerable, urban Mozambique
Published: 2025-11-18
Subjects: Public Health
Background: Diarrhea remains one of the leading causes of morbidity and mortality for children under the age of five, despite reductions in its overall global burden in recent decades. However, climate change, and its associated meteorological conditions - heavy rainfall, temperature, flooding - has the potential to impede or reverse progress that has been made toward alleviating the burden of [...]
The slip distributions of the 1952 and 2025 Kamchatka earthquakes from tsunami waveforms recorded around the Pacific Ocean
Published: 2025-11-18
Subjects: Earth Sciences, Geophysics and Seismology, Physical Sciences and Mathematics
The July 2025 Kamchatka earthquake (Mw 8.8) generated Pacific-wide tsunamis. Inversion of 40 DART bottom pressure records around the Pacific Ocean revealed a large (~ 9 m) slip at 200 – 400 km southwest of the epicenter, closely matching the USGS finite fault model based on teleseismic data. In this region, a similarly large megathrust earthquake (M ~ 9) occurred in 1952. The tsunami waveforms [...]
Interplay between subsidence and sediment flux in the filling of the North Pyrenean retro-foreland basin during the Eocene (Corbières, France)
Published: 2025-11-19
Subjects: Earth Sciences
External forcings, such as climate and tectonics, influence sedimentary basin fills. In turn, sedimentary archives provide key information on variations in accommodation and sediment flux over time, which record paleoclimate and tectonic conditions. However, the impacts of accommodation and flux on sedimentation must be disentangled before understanding their specific influence on surface [...]
Long-term incubations reveal geochemical controls on wood biomass preservation at the anoxic sediment-water interface
Published: 2025-11-21
Subjects: Life Sciences
Ocean-based carbon dioxide removal (CDR) strategies increasingly consider biomass burial in anoxic marine basins as a pathway for long-term carbon storage. To evaluate its stability and environmental impact, we conducted 14-month bottle incubations testing three configurations of terrestrial wood under anoxic conditions: suspended in the water column, placed on the sediment surface, and buried [...]
Access to Monitoring Data Reduces Methane Intensity at Operational Oil and Gas Facilities
Published: 2025-11-21
Subjects: Environmental Monitoring, Oil, Gas, and Energy
Methane intensity is defined as methane gas emitted to the atmosphere per oil and gas product throughput at various steps in the supply chain. It is the standard metric used by industry stakeholders to assess methane emissions performance. Many studies have assessed the capabilities of methane emission measurement systems, but no studies have quantified the effect on methane intensity of oil and [...]
Climate Change Perceptions and Water Security: Evidence from Low-Income Urban Communities of Dar es Salaam, Tanzania
Published: 2025-11-19
Subjects: Public Health
Background Water scarcity is being exacerbated by climate change, especially in low- and middle-income countries with limited adaptation capacity. Methods Between June and October 2023, we conducted a cross-sectional survey of 364 households in three districts of Dar es Salaam, Tanzania. We used structured questionnaires to evaluate the household's demographic characteristics, knowledge of [...]
Anthropogenic Environmental Change and Sexual and Reproductive Health in Southeast Asia: A Scoping Review
Published: 2025-11-19
Subjects: Public Health
While often neglected, sexual and reproductive health (SRH) is a significant dimension of the health implications of global anthropogenic environmental change, including climate change. However, literature on the topic is scarce and largely neglects low and middle-income countries (LMICs) and regions such as Southeast Asia. We thus aimed to synthesise the literature connecting anthropogenic [...]
Agrivoltaics can reduce heat exposure for farmworkers
Published: 2025-11-20
Subjects: Agriculture
Heat exposure endangers over 850 million farmworkers, with agricultural labor projected to account for 60% of heat-related working-hour losses by 2030. Agrivoltaic systems, which integrate solar panels with agriculture, may reduce this risk by modifying the thermal environment farmworkers operate within, yet their impact on heat exposure remains unquantified. We evaluate wet bulb globe [...]
3-D Elastic Time-Reverse Imaging of a Linear Void Anomaly
Published: 2026-01-28
Subjects: Geophysics and Seismology
Imaging meter-scale subsurface heterogeneities such as void spaces remains a difficult task for most established near-surface seismic methods. One strategy for addressing this challenge is to isolate and use surface waves backscattered from lateral heterogeneities to identify and characterize the sources of scattered energy. Seismic methods associated with this strategy, though, often require [...]
Attention-Based Deep Learning for Runoff Forecasting: Evaluating the Temporal Fusion Transformer Against Traditional Machine Learning Models
Published: 2025-11-21
Subjects: Engineering, Life Sciences
Reliable runoff forecasting is critical for water management and flood preparedness in Nepal’s steep, data-scarce catchments. Traditional models such as SWAT provide process insights but demand extensive calibration and detailed inputs often unavailable in such regions. Recent advances in attentionbased deep learning offer new opportunities to capture temporal dependencies with improved [...]
A systematic review of microplastic pollution in rivers across Asia
Published: 2025-11-21
Subjects: Physical Sciences and Mathematics
Microplastics are widely distributed in the aquatic ecosystem globally. They pose potential risks and harm to the ecosystem and human health. Contamination of river environments by microplastics has raised concern due to its negative effect on the aquatic system. Asian rivers serve the world’s most populous continent, encompassing many developing countries experiencing rapid development and [...]
