Mantle avalanches in a Venus-like stagnant lid planet

Madeleine Kerr, Dave Stegman

Published: 2024-06-28
Subjects: Planetary Geophysics and Seismology, Planetary Mineral Physics, Planetary Sciences

Stagnant lid planets are characterized by a globe-encircling, conducting lid that is thick and strong, which leads to reduced global surface heat flows. Consequently, the mantles of such planets can have warmer interiors than Earth, and interestingly, a pyrolitic mantle composition under warmer conditions is predicted to have a distinctly different mantle transition zone compared to the [...]

Subjects: Earth Sciences

This work discusses the feasibility of multiple linear regression in predicting water/CO2 relative permeability using training and testing datasets from two nearby wells, separately, of the Lower Cretaceous Lakota Sandstone, Jurassic Hulett Sandstone, and Pennsylvanian Minnelusa Formation at the Dry Fork Station site. The outcome is promising as the predicted and measured relative permeability [...]

Thermo-Hydro-Mechanical Modeling of Geothermal Energy Systems in Deep Mines: Uncertainty Quantification and Design Optimization

Le Zhang, Anne-Catherine Dieudonné, Alexandros Daniilidis, et al.

Published: 2024-06-28
Subjects: Earth Sciences

Exploiting geothermal energy using existing deep mining systems streamlines the development of geothermal systems while addressing the cooling needs of deep mines. However, the combined effects of low-temperature and high-pressure injection during geothermal operations adversely impact the stability of deep mine drifts. This makes it crucial to reliably assess the stability of the drifts and [...]

Dynamic Rupture Modeling in a Complex Fault Zone with Distributed and Localized Damage

Md Shumon Mia, Chunhui Zhao, Ahmed Elbanna, et al.

Published: 2024-06-28
Subjects: Physical Sciences and Mathematics

Active fault zones have complex structural and geometric features that are expected to affect earthquake nucleation, rupture propagation with shear and volumetric deformation, and arrest. Earthquakes, in turn, dynamically activate co-seismic off-fault damage that may be both distributed and localized, affecting fault zone geometry and rheology, and further influencing post-seismic deformation and [...]

Win, lose, or draw: evaluating dynamic thermal niches of northeast Pacific groundfish

Eric Ward, Sean C. Anderson, Lewis Barnett, et al.

Published: 2024-06-27
Subjects: Marine Biology

Understanding the dynamic relationship between marine species and their changing environments is critical for ecosystem based management, particularly as coastal ecosystems experience rapid change (e.g., general warming, marine heat waves). In this paper, we present a novel statistical approach to robustly estimate and track the thermal niches of 30 marine fishes along the west coast of North [...]

Regional differences in soil stable isotopes and vibrational features at depth in three California Grasslands

Leila Maria Wahab, Stephany Chacon, Sora Kim, et al.

Published: 2024-06-27
Subjects: Life Sciences

There are major gaps in our understanding of how Mediterranean ecosystems will respond to anticipated changes in precipitation. In particular, limited data exists on the response of deep soil carbon dynamics to changes in climate. In this study we wanted to examine carbon and nitrogen dynamics between topsoils and subsoils along a precipitation gradient of California grasslands. We focused on [...]

Increasing precipitation will offset the impact of warming air temperatures on glacier volume loss in the monsoon-influenced Himalaya until 2100 CE

Ann Rowan, Anya M Schlich-Davies, Andrew N Ross, et al.

Published: 2024-06-27
Subjects: Glaciology

Himalayan glaciers are projected to shrink by over 50% this century due to rising air temperatures. However, the impact of future precipitation change on glacier evolution remains uncertain. Here we explore these precipitation effects by simulating the future evolution of Khumbu Glacier in the monsoon-influenced Himalaya until 2300 CE. Khumbu Glacier is committed by historical warming to volume [...]

Regionally Developed Giant Sand Injection Complexes in the Northern North Sea

Oluwatobi Olobayo, Mads Huuse, Christopher Aiden-Lee Jackson

Published: 2024-06-26
Subjects: Education

The Northern North Sea (NNS) is an archetype Giant Injected Sand Province (GISP). Previous studies have documented individual stratigraphically-bound injectite complexes in the North Sea and beyond. Despite two decades of continuous studies, there are still speculations in terms of parent sand identification, visible pathways, fluid source, overpressure generation mechanisms and triggers. This [...]

State-dependency of dynamic and thermodynamic contributions to effective precipitation changes

Laura Braschoss, Nils Weitzel, Jean-Philippe Baudouin, et al.

Published: 2024-06-26
Subjects: Climate, Oceanography and Atmospheric Sciences and Meteorology

Reliable projections of the future hydrological cycle are needed for designing adaptation and mitigation measures under global warming. However, uncertainties in the projected sign and magnitude of effective precipitation changes (precipitation minus evaporation, P-E) remain high. Here, we examine the state-dependency of circulation, temperature, and relative humidity contributions to P-E changes [...]

Lidar-based snow monitoring: cable car deployment in the Austrian Alps

Berin Dikic, Thomas Goelles, Christoph Gaisberbger, et al.

Published: 2024-06-26
Subjects: Environmental Monitoring, Fresh Water Studies, Water Resource Management

Traditional methods for surveying the spatial and temporal distribution of snow are often time-consuming, costly, and potentially hazardous. To address these challenges, we propose a novel approach utilizing a newly developed sensor system based on cost-effective industrial lidar sensors. This system is designed to be mounted on cable cars, enabling continuous envi- ronmental scanning during [...]

A space-time simulator for hourly wind and solar energy fields

Yash Vijay Amonkar, David J Farnham, Upmanu Lall

Published: 2024-06-26
Subjects: Engineering

Spatially distributed renewable energy generation poses unique risks to power systems since the aggregate amount of energy produced in any hour depends on the spatial correlation structure of the sources. Moreover, the spatial correlation structure can vary with the time of day and season and depend on the state of the large-scale climate. These features pose a challenge for resource adequacy [...]

Radiometric dating (40Ar/39Ar and 14C), compositions, and erupted volumes of volcanoes of the Valle de Santiago area (Michoacán-Guanajuato Volcanic Field, México)

Subjects: Glaciology

The conditions under which ice fractures and calves icebergs from Antarctic ice shelves are poorly understood due largely to a lack of relevant observations. Though previous studies have estimated the stresses at which ice fractures in the laboratory and through sparse observations, there remains significant uncertainty in the applicability of these results to naturally deforming glacier ice on [...]

Subjects: Earth Sciences, Geochemistry, Geology, Other Earth Sciences, Volcanology

Identifying the storage depths of melt-dominated magma bodies prior to eruption is critical for understanding magma transport, eruption hazards, and magma body longevity. Rhyolite-MELTS has been used effectively to calculate pre-eruptive storage pressures for silicic magma bodies in the upper crust (~100-350 MPa), but its precision and accuracy in very low-pressure systems (<100 MPa) has not [...]
