A data-driven framework for landslide size space-time modelling
Published: 2022-10-10
Subjects: Applied Statistics, Geomorphology, Multivariate Analysis, Statistical Models
Landslide susceptibility assessment using data-driven models has predominantly focused on predicting where landslides may occur and not on how large they might be. The spatio-temporal evaluation of landslide susceptibility has only recently been addressed, as a basis for predicting where and when landslides might occur. The present study combines these new developments by proposing a data-driven [...]
Skilful forecasts of summer rainfall in the Yangtze River Basin from November
Published: 2022-10-10
Subjects: Atmospheric Sciences, Climate
Variability in the East Asian Summer Monsoon (EASM) brings the risk of heavy flooding or drought to the Yangtze River Basin, with potentially devastating impacts. Early forecasts of the likelihood of enhanced or reduced monsoon rainfall can enable better management of water and hydropower resources by decision-makers, supporting livelihoods and major economic and population centres across Eastern [...]
Seismicity modulation due to hydrological loading in a stable continental region: a case study from the Jektvik swarm sequence in Northern Norway
Published: 2022-10-10
Subjects: Geophysics and Seismology
Seismic swarms have been observed for more than 40 years along the coast of Nordland, Northern Norway. However, the detailed spatio-temporal evolution and mechanisms of these swarms have not yet been resolved due to the historically sparse seismic station coverage. An increased number of seismic stations now allows us to study a nearly decade-long swarm sequence in the Jektvik area during the [...]

Escalating wildfires in Siberia driven by multiple climate feedbacks under a warming Arctic
Published: 2022-10-08
Subjects: Earth Sciences
Wildfire in Siberia is of paramount importance in the carbon cycle and climate change as it is a major disturbance in the pan-Arctic ecosystems. In recent decades, the Siberian wildfire regime has been changing; however, less is known about the key climatic drivers and the underlying feedback over these vulnerable fire-prone landscapes. Here, based on ground-based and satellite observations and [...]
FIELD LEVEL VARIATION INFLUENCED OUTCOMES MORE THAN N-FERTILISER, FYM, COVER CROPS OR THEIR LEGACY EFFECTS FOLLOWING CONVERSION TO A NO-TILL ARABLE SYSTEM
Published: 2022-10-08
Subjects: Agriculture, Biogeochemistry, Earth Sciences, Environmental Chemistry, Other Earth Sciences, Other Environmental Sciences, Soil Science
Crop establishment in no-till arable systems benefits from favourable soil conditions. Combined with the incorporation of crop residues and manures, no-till can influence soil organic carbon (SOC) and organic matter (SOM) dynamics, crop productivity and nutrient cycling. These processes are shaped by spatial and temporal factors and associated microbial processes. There is a lack of diachronic [...]
Distributed Acoustic Sensing in a Greenlandic Outlet Glacier: Developing Machine Learning Approaches to Benefit Cryoseismic Data Analysis
Published: 2022-10-08
Subjects: Geophysics and Seismology, Glaciology, Other Computer Sciences
The recognition of Distributed Acoustic Sensing (DAS) as a valuable tool for glaciological seismic applications is growing. However, besides the logistical challenges of installing fibre-optic cable, the volume of DAS data that can be collected in a field campaign poses computational challenges. In this paper, we show the potential of active-source DAS to image and characterise subglacial [...]
Characterising the internal structural complexity of the Southern North Sea Zechstein Supergroup Evaporites
Published: 2022-10-08
Subjects: Earth Sciences, Geology, Tectonics and Structure
The internal complexity present within layered evaporite sequences is often an overlooked feature in sedimentary basins, with attention frequently concentrating on the external geometries that salt bodies form. Through the availability of large areas of 3D seismic data and new seismic imaging techniques the opportunity to view the internal structures that form within layered evaporites allows for [...]
Rapid quench piston cylinder apparatus: an improved design for the recovery of volatile-rich geological glasses from experiments at 0.5 - 2.5 GPa
Published: 2022-10-08
Subjects: Earth Sciences
The accurate and precise determination of the compositions of silicate glasses formed from melts containing the volatile components H2O and CO2 recovered from high-pressure, high-temperature experiments is essential to our understanding of geodynamic processes taking place within the planet. Silicate melts are often difficult to analyse chemically because the formation of quench crystals and [...]
Coupled otolith and foraminifera oxygen and carbon stable isotopes evidence paleoceanographic changes and fish metabolic responses
Published: 2022-10-06
Subjects: Earth Sciences
Capturing the mechanisms leading to the local extirpation of a species in deep-time is a challenge. Combining stable oxygen and carbon isotopic analyses on benthic and planktonic foraminifera and the otoliths of pelagic and benthic fish species, we reveal here the paleoceanographic regime shifts changes that took place in the Eastern Mediterranean from 7.2 to 6.5 Ma, in the precursor phase to the [...]
Deterministic icehouse and greenhouse climates throughout Earth history
Published: 2022-10-06
Subjects: Climate, Geochemistry
Some theories posit that icehouse (with polar ice sheets) and greenhouse (ice-free) states throughout Earth history are not deterministic, but bistable—both states may occur for the same level of radiative forcing. If correct, then the climate state that persists for millions of years can depend on which state already existed, giving the system a `memory’ effect. However, on these timescales the [...]
Client-side Web-based Model Coupling using Basic Model Interface for Hydrology and Water Resources
Published: 2022-10-06
Subjects: Civil and Environmental Engineering, Computational Engineering, Other Engineering
A recent trend in hydroinformatics has been the growing number of data, models, and cyber tools which are web accessible, each aiming to improve common research tasks in hydrology through web technologies. Coupling web-based models and tools holds great promise for an integrated environment that can facilitate community participation, collaboration, and scientific replication. There are many [...]
Effect of mineral heterogeneity on fracture dissolution in carbonate-rich caprocks during subsurface CO2 injection
Published: 2022-10-03
Subjects: Environmental Sciences
Chemical interactions between CO2, brine, and caprock-forming minerals might lead to dissolution of the fractures present in the caprock of CO2 storage sites. One factor that can affect the chemically induced fracture alterations is mineral heterogeneity in the caprock. In this study, we investigate the effect of mineral heterogeneity on fracture dissolution of four carbonate-rich caprock [...]

Published: 2022-10-03
Subjects: Other Earth Sciences
We present a mobile dataset of ultrafine particles (UFPs) in Lancaster, UK, with measurements taken by car and bike over 5 days in May 2022. UFPs are a constituent of air pollution and comprise of particulate matter (PM) less than 0.1μm in diameter. UFPs are unregulated and less measured than larger constituents of PM, despite being harmful to health and an important part of the atmospheric and [...]
Bayesian inference on the initiation phase of the 2014 Iquique, Chile, earthquake
Published: 2022-10-03
Subjects: Earth Sciences, Geophysics and Seismology, Physical Sciences and Mathematics
We investigate the initiation phase of the 2014 Mw8.1 Iquique earthquake in northern Chile. In particular, we focus on the month preceding the mainshock, a time period known to exhibit an intensification of the seismic and aseismic activity in the region. The goal is to estimate the time-evolution and partitioning of seismic and aseismic slip during the preparatory phase of the mainshock. To do [...]
