Limited warming of Middle Miocene arid low-latitude climates: application of clumped isotopes in sabkha environments
Published: 2024-10-10
Subjects: Physical Sciences and Mathematics
Reconstructing past climatic conditions in arid and hot environments is challenging due to a scarcity of climate archives. However, this task is crucial for assessing the sensitivity of these areas to climate change. The lack of reliable proxies currently prevents precise and absolute temperature and moisture reconstructions. Clumped isotopes on sabkha calcite might alleviate this situation. In [...]
The link between water and ferric iron in Earth's lower mantle
Published: 2024-10-10
Subjects: Earth Sciences, Geochemistry, Mineral Physics
As the most massive geochemical reservoir, the lower mantle affects Earth's budget of volatile elements, including hydrogen or H2O. The properties of minerals in Earth's lower mantle are further affected by changes in the electronic configurations of iron cations, i.e., spin transitions. Potential feedback between deep H2O retention and spin transitions in mantle minerals, however, remain [...]
Interseismic deformation fingerprints on the hyperarid coastal landscape in North Chilean subduction
Published: 2024-10-10
Subjects: Earth Sciences, Geology, Geomorphology, Geophysics and Seismology, Tectonics and Structure
Along-strike seismotectonic behavior of subduction megathrusts feeds back into the forearc deformation as elastic and permanent deformation. However, whether and how short-term elastic deformation reflects long-term permanent deformation in the forearc and shapes the coastal region remains unclear. To evaluate the forearc deformation, we analyze the interseismic surface deformation obtained from [...]
Slip-tremor interaction at the very beginning of Episodic Tremor and Slip in Cascadia
Published: 2024-10-10
Subjects: Geophysics and Seismology
In Cascadia, the concomitance of slow slip events (SSE) and tremors during Episodic Tremor and Slip (ETS) episodes is well documented. Brittle tremor patches embedded in the ductile background deforming aseismically is the most common sketch for the fault structure, but whether tremor patches impact the SSE process is under debate. This study focuses on the initiation stage of major Cascadia [...]
Improving an Integrative Framework of Health System Resilience and Climate Change: Lessons from Bangladesh and Haiti
Published: 2024-10-10
Subjects: Public Health
The analysis of health system resilience has progressed significantly, yet there remains a wide diversity in the conceptual frameworks used. The ClimHB conceptual framework, developed in 2019, integrates two influential models: the Levesque model of healthcare access and DFID's resilience framework. Designed to study health system resilience in response to climate-induced events, the ClimHB [...]
Modelling intra-parasequence reservoir heterogeneity with a process-mimicking algorithm: a case study from the Kenilworth Member, Blackhawk Formation
Published: 2024-10-09
Subjects: Physical Sciences and Mathematics
Wave dominated, shallow marine siliciclastic successions form some of the most prolific oil and gas reservoirs worldwide, where individual parasequences comprise the main flow units. Within parasequences, these reservoirs have been traditionally modelled as simple shore-parallel facies belts, given their reputation as simple reservoirs with subtle spatial heterogeneity in petrophysical [...]
ml4xcube: Machine Learning Toolkits for Earth System Data Cubes
Published: 2024-10-09
Subjects: Computer and Systems Architecture, Computer Engineering, Engineering, Geography, Remote Sensing, Social and Behavioral Sciences
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) [...]

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 [...]

Instability in the geological regulation of Earth’s climate
Published: 2024-10-06
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 [...]
