Rapidly changing climate conditions and the increase in extreme events are posing severe challenges to human life and infrastructure, requiring sophisticated analytical capabilities for hazard prediction and disaster risk management. Earth System Data Cubes (ESDCs) have become an essential tool in Earth System Sciences (ESS) by organizing large-scale, multivariate environmental datasets into a [...]
A New Neural Network Retrieval of Liquid Water Path Optimized for Mixed-Phase Cold Air Outbreaks Using Radiometer and Radar Observations
Published: 2024-10-09
Subjects: Physical Sciences and Mathematics
Cold-air outbreaks over high latitude oceans typically include mixed-phase clouds and precipitation, in particular liquid clouds that support snow and graupel through ice growth processes. The partitioning of the total water into the liquid and ice phases impacts both weather and climate prediction, but accurate measurements on the phase partitioning remain difficult to acquire, especially [...]
From bench to beach: Assessing the reliability of community-based qPCR monitoring for recreational water quality
Published: 2024-10-09
Subjects: Public Health
Quantitative polymerase chain reaction (qPCR) is increasingly used in recreational water quality monitoring, yet the temporal variability of indicator concentrations as well as the breadth of locations and biological hazards to be monitored continues to present a challenge. Participatory approaches such as community-based monitoring (CBM) are valued in environmental research but the potential for [...]
BUSINESS SUSTAINABILITY PRACTICES IN MICRO AND SMALL ENTERPRISES: A SYSTEMATIC REVIEW
Published: 2024-10-08
Subjects: Environmental Studies
Micro and small enterprises (MSEs) are essential for economic and social development globally, as they represent a significant proportion of employment and production. Nonetheless, these enterprises confront substantial difficulties in incorporating sustainable practices, largely attributable to their limited financial resources and capacity, difficulties in accessing relevant information, [...]
Structural weaknesses in ice mélange revealed by high resolution ICEYE SAR imagery
Published: 2024-10-08
Subjects: Glaciology, Physical Sciences and Mathematics
The mixture of icebergs and sea ice in tidewater glacier fjords, known as ice mélange, is postulated to impact iceberg calving directly through physical buttressing and indirectly through freshwater fluxes altering fjord circulation. In this contribution, we assess the textural characteristics of ice mélange in summer and winter at the terminus of Helheim Glacier in Greenland using high [...]
Virtual laser scanning of dynamic scenes (VLS-4D): Current approaches and future perspectives in remote sensing
Published: 2024-10-07
Subjects: Computer Sciences, Earth Sciences, Environmental Sciences, Geographic Information Sciences, Geography, Numerical Analysis and Scientific Computing, Physical and Environmental Geography, Remote Sensing
Virtual laser scanning (VLS) has proven to be a useful tool for survey planning, method development and training data generation in a variety of areas of Earth and environmental sciences. Until recently, most applications have used static representations of the real or a fictive environment, neglecting the inherent dynamics of our world, that also affect Light Detection and Ranging (LiDAR) [...]
Efficiency and heat transport processes of low-temperature aquifer thermal energy storage systems: new insights from global sensitivity analyses
Published: 2024-10-07
Subjects: Geology, Natural Resources and Conservation, Oil, Gas, and Energy, Sustainability
Aquifer Thermal Energy Storage (ATES) has great potential to mitigate CO2 emissions associated with the heating and cooling of buildings and offers wide applicability. Thick productive aquifer layers have been targeted first, as these are the most promising areas for ATES. Regardless, there is currently an increasing trend to target more complex aquifers such as low-transmissivity and alluvial [...]
Practical guidelines for DFIT interpretation using the ‘compliance method’ procedure from URTeC-2019-123
Published: 2024-10-05
Subjects: Mining Engineering
This article provides practical tips for interpreting Diagnostic Fracture Injection Tests (DFITs) using the ‘compliance method’ procedure initially developed by McClure et al. (2016) and refined in the paper URTeC-2019-123, which summarized results from a joint industry study (McClure et al., 2019). The results from McClure et al. (2016) demonstrated that common practices for stress estimation [...]
Instability in the geological regulation of Earth’s climate
Published: 2024-10-05
Subjects: Biogeochemistry
Negative feedback between climate and atmospheric CO2, as mediated via weathering of silicate minerals, is thought to provide the dominant regulation of Earth’s climate on geological timescales. In contrast, we show here that faster feedbacks involving organic matter are critical and create unexpected instability in the system. Specifically, using an Earth system model, we show how organic carbon [...]
How can Light Pollution over the City of Mumbai be Assessed and Reversed?
Published: 2024-10-05
Subjects: Earth Sciences, Environmental Sciences, Physics
Light pollution, which adversely affects entire ecosystems, is a lesser-known but completely reversible form of pollution. The financial capital of India, Mumbai has been experiencing a steady rise in light pollution levels. This research article aims to answer the question “How can light pollution over the city of Mumbai be assessed and reversed?” It uses satellite data to map radiance levels [...]
Questioning Dark Oxygen Production in the Deep-sea Ferromanganese Nodule Field
Published: 2024-10-04
Subjects: Earth Sciences, Geochemistry, Geology, Oceanography
Previous studies have concluded that the natural process where oxygen is consumed as decomposition of organic matter that supplied from shallow waters occurs on the deep-sea floor. Sweetman et al.1 presented the surprising observation that deep-sea ferromanganese nodules generate oxygen, which they labelled as dark oxygen production. The authors claimed that oxygen was generated through the [...]
Coseismic slip and afterslip of the 2024 Hyuganada earthquake modulated by subducted seamount
Published: 2024-10-04
Subjects: Geophysics and Seismology
Subducted rough topography complicates seismic and aseismic slip behavior. The 2024 M 7.1 Hyuganada earthquake occurred along the megathrust with ridge subduction. We inferred coseismic slip and afterslip using geodetic displacements to observationally illustrate the role of subducted seamounts in modulating seismic and aseismic slip processes. The inferred mainshock was confined in the down-dip [...]
