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 [...]
GEOCHEMICAL AND MINERALOGICAL STUDY OF THE CRETACEOUS SEDIMENTS IN KERI KERI, FIKA, GONGILA, AND BIMA SANDSTONE FORMATION BORNU BASIN, NORTH-EASTERN NIGERIA
Published: 2022-10-24
Subjects: Physical Sciences and Mathematics
The mineralogical and geochemical composition of Cretaceous and Tertiary sediments of the Bornu Basin, northeastern Nigeria penetrated by Kanadi Wells, have been studied towards deducing aspects of their derivation and deposition. The sediments comprising the Bima Sandstone Formation, sandy-shale Gongila Formation, and, clayey and shaley Fika Formation are mainly composed of quartz (35-58%) and [...]
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 [...]

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 [...]
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 [...]
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 [...]
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 [...]
Quantitative constraints on flood variability in the rock record.
Published: 2022-10-27
Subjects: Earth Sciences, Physical Sciences and Mathematics
Floods determine river behaviour in time and space. Yet quantitative measures of discharge variability from geological stratigraphy are sparse, even though they are critical to understand landscape sensitivity to past and future environmental change. Here we show how storm-driven river floods in the geologic past can be quantified, using Carboniferous stratigraphy as an exemplar. The geometries [...]
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 [...]
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 [...]
Storage Integrity during Underground Hydrogen Storage in Depleted Gas Reservoirs

Subjects: Engineering
The transition of energy from fossil fuels to renewable energy particularly hydrogen is becoming the centre of decarbonization and roadmap to achieve net-zero carbon emission. To meet the requirement of large-scale hydrogen storage as a key part of hydrogen supply chain, underground hydrogen storage can be the ultimate solution to economically store hydrogen thus meet global energy demand.

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 [...]
