Bayesian reconstruction of sea-level and hydroclimates from coastal landform inversion
Published: 2024-02-10
Subjects: Earth Sciences, Geology, Geomorphology, Tectonics and Structure
Quantifying Quaternary sea-level changes and hydroclimatic conditions is an important challenge given their intricate relation with paleo-climate, ice-sheets and geodynamics. The world’s coastlines provide an enormous geomorphologic archive, from which forward landscape evolution modelling studies have shown their potential to unravel paleo sea-levels, albeit at the cost of assumptions to [...]
From nutrients to fish: Impacts of mesoscale processes in a global CESM-FEISTY eddying ocean model framework
Published: 2024-02-09
Subjects: Life Sciences
The ocean sustains ecosystems that are essential for human livelihood and habitability of the planet. The ocean holds an enormous amount of carbon, and serves as a critical source of nutrition for human societies worldwide. Climate variability and change impacts marine biogeochemistry and ecosystems. Thus, having state-of-the-art simulations of the ocean, which include marine biogeochemistry and [...]
A new calibration of the OPAM thermobarometer for anhydrous and hydrous mafic systems
Published: 2024-02-09
Subjects: Earth Sciences
Melt-based thermobarometers are essential tools to recover pre-eruptive magma storage conditions through their application to bulk rock and liquid chemistry. In active volcanic systems, thermobarometric results can be combined with independent geophysical data during or after an eruption to validate conceptual models. In this contribution, we revisit the thermobarometer for melts equilibrated [...]
Magma solidification effects during sill emplacement: insights from laboratory experiments
Published: 2024-02-09
Subjects: Physical Sciences and Mathematics
Igneous sills and interconnected sill complexes transport magma both vertically through the Earth’s crust and laterally over potentially long distances. Although cooling and solidification of magma are acknowledged to play a major role in the propagation and emplacement of sills, their contributions to sill formation remain poorly understood. Here, the effects of solidification on sill [...]
DAS to Discharge: Using Distributed Acoustic Sensing (DAS) to infer glacier runoff
Published: 2024-02-08
Subjects: Earth Sciences, Geophysics and Seismology, Glaciology, Physical Sciences and Mathematics
Observations of glacier melt and runoff are of fundamental interest in the study of glaciers and their interactions with their environment. Considerable recent interest has developed around distributed acoustic sensing (DAS), a sensing technique which utilizes Rayleigh backscatter in fiber optic cables to measure the seismo-acoustic wavefield in high spatial and temporal resolution. Here, we [...]
WITHDRAWN: The potential of terrestrial and aquatic molluscs for the temporal analysis of Deckenschotter deposits and younger Quaternary sediments from the Swiss Plateau
Published: 2024-02-08

Azimuthal Variation in the Spectra of the 2019 Ridgecrest Earthquake Clusters and its Application to Understanding Fault Zone Structure
Published: 2024-02-08
Subjects: Physical Sciences and Mathematics
We first show through dynamic rupture models that FDZs can amplify high-frequency waves along directions close to fault strike and the amplified frequency band may be used to estimate the width and velocity contrast of the FDZ. Then, we identify this high-frequency amplification in the spectra of M1.5–3 earthquakes from the 2019 Ridgecrest earthquake sequence. We cluster the earthquakes by [...]
An aminostratigraphy for the Quaternary of the Swiss Plateau
Published: 2024-02-08
Subjects: Analytical Chemistry, Earth Sciences, Geochemistry, Other Earth Sciences, Stratigraphy
Here we develop an amino acid chronology to help establish a dated sequence for the important Early Pleistocene Höhere and Tiefere Deckenschotter lithostratigraphic units, as well as other Quaternary deposits from the Swiss Plateau. Age discrimination is possible between the Quaternary sites from the Swiss Plateau in six different biominerals: Bithynia opercula, shell fragments from Fruticola, [...]
Collaborative systems thinking analysis for enhancing climate smart agricultural (CSA) technology adoption in Africa
Published: 2024-02-08
Subjects: Agriculture
Agricultural technology adoption is a critical driver of sustainable development, particularly in developing regions where agriculture plays a pivotal role in food security and livelihoods. This study combines network analysis, including causal loop diagrams (CLD), with centrality metrics, to uncover key leverage points within the system where targeted interventions can yield significant impacts [...]
Impacts of global warming on hurricane-driven insurance losses in the United States
Published: 2024-02-08
Subjects: Climate, Oceanography and Atmospheric Sciences and Meteorology
North Atlantic hurricanes are a major driver of property losses in the United States and a critical peril for the insurance industry on a global scale. Despite the growing scientific consensus around the potential impacts of global warming on North Atlantic hurricanes, the implications for the insurance industry are still largely unquantified. We address this question by drawing on 70 years of [...]
Aggregates versus pores? A survey among soil scientists about their perspectives on soil structure
Published: 2024-02-08
Subjects: Soil Science
Despite mostly uniform definitions of soil structure, two perspectives on it have been juxtaposed in the past: the “aggregate perspective” and the “pore perspective”. The debate as represented in the literature appears to be polarised. To test whether this is also the case in the wider soil science community, an online survey was conducted asking about soil [...]
Nitrogen Availability and Denitrification in Urban Agriculture and Regreened Vacant Lots
Published: 2024-02-08
Subjects: Environmental Sciences
Many cities demolish abandoned homes and create regreened vacant lots (RVLs), and an increasingly popular, high-intensity use of RVLs is as urban agriculture (UA) sites. UA may potentially result in higher nitrogen (N) runoff to aquatic ecosystems, but this potential has not been quantified. We examined the role that varying land reuse intensity plays in determining potential for N export via [...]
Climate and Air Quality Impact of Using Ammonia as an Alternative Shipping Fuel
Published: 2024-02-07
Subjects: Atmospheric Sciences, Oil, Gas, and Energy
As carbon-free fuel, ammonia has been proposed as an alternative fuel to facilitate maritime decarbonization. Deployment of ammonia-powered ships is proposed as soon as 2024. However, emissions of NOx, NH3 and N2O resulting from ammonia combustion could cause impacts on air quality and climate. In this study, we assess whether and under what conditions switching to ammonia fuel might affect [...]
Physicochemical Factors and Urban Land-Use Characteristics Associated with Resistance to Precipitation in Estuaries Vary Across Scales
Published: 2024-02-07
Subjects: Physical Sciences and Mathematics
Urban estuaries are subject to frequent stressors, including nutrient loading and hydrological flashiness, which worsen water quality and disrupt ecosystem function. Land use changes associated with urbanization, as well as atypical precipitation conditions can exacerbate stress on estuarine health. However, generalizable patterns and parameters involved in estuarine responses to urbanization and [...]
Roman Ports in the Mediterranean: Geomorphology, Environment and Resilience
Published: 2024-02-05
Subjects: Social and Behavioral Sciences
Classical ports in the Mediterranean Sea existed not only in a social, economic and technical contexts but also in a geomorphological context. This geomorphological context, which includes both the harbour landform and the catchment (if any) is a function of the geomorphology of coasts and catchments (including neotectonics) and marine factors (bathymetry, low amplitude tides, surges, tsunamis [...]
