Trait-based modeling revealed higher microbial diversity leads to greater ecological resilience in response to an ecosystem disturbance
Published: 2022-10-14
Subjects: Biogeochemistry, Earth Sciences, Environmental Microbiology and Microbial Ecology Life Sciences, Microbiology, Oceanography, Oil, Gas, and Energy, Physical Sciences and Mathematics, Sustainability, Terrestrial and Aquatic Ecology
To quantitatively understand the ecological resilience of an ecosystem with specialized habitats, we focused on deep-sea microbial communities and simulated the response of diverse microbes in specialized habitats to a pulse ecosystem disturbance - the Deepwater Horizon Oil Spill in the Gulf of Mexico. Two microbial communities with equivalent metabolic libraries were acclimated to the presence [...]
Inclination and heterogeneity of layered geological sequences influence dike-induced ground deformation
Published: 2022-10-14
Subjects: Physical Sciences and Mathematics
Constraints on the amount and pattern of ground deformation induced by dike emplacement are important for assessing potential eruptions. The vast majority of ground deformation inversions made for volcano monitoring during volcanic unrest assume that dikes are emplaced in either an elastic-half space (a homogeneous crust) or a crust made of horizontal layers with different mechanical properties. [...]
Harnessing hyperspectral imagery to map surface water presence and hyporheic flow properties of headwater stream networks
Published: 2022-10-14
Subjects: Physical Sciences and Mathematics
Growth and contraction of headwater stream networks determine the extent and quality of ecologically critical habitat, and open a window into the storage dynamics of catchments. A fundamental challenge is observation of the process itself: wetted channel extent is highly dynamic in space and time, with the length of wetted channel sometimes varying by orders of magnitude over the course of a [...]
On spatially correlated observations in a particle method for subsidence estimation
Published: 2022-10-13
Subjects: Engineering, Physical Sciences and Mathematics
The particle method is an ensemble-based data assimilation method for state- and parameter estimation in a quasi-static problem. We apply the particle method in two different experiments with models of increasing complexity. The first model, which calculates subsidence for a single observation point due to a single source of strain, considers uncorrelated parameters and observations. In the [...]
Optimising Renewable Generation Configurations of Off-Grid Green Ammonia Production Systems considering Haber-Bosch Flexibility
Published: 2022-10-12
Subjects: Engineering
Green ammonia has received increasing interest for its potential as an energy carrier in the international trade of renewable power. This paper considers Australia’s prospects for green ammonia production from an exporter’s perspective by highlighting Australia’s competitive advantage in renewable resource quality and seasonal complementarity to its potential trade buyers. Although renewable [...]
A Global-Scale Characterization of Streamflow Extremes
Published: 2022-10-12
Subjects: Engineering
The increasing risk of floods across the globe needs focused attention because of the extensive damage to human lives and economy. A comprehensive understanding of its causative factors is of vital importance. Yet catchment characterization studies are generally limited to case studies or regional domains. A comprehensive global characterization is currently unavailable, which requires collecting [...]
Storage Integrity during Underground Hydrogen Storage in Depleted Gas Reservoirs
Published: 2022-10-12
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. [...]
The cryptic stratigraphic record of the syn- to post-rift transition in the offshore Campos Basin, SE Brazil
Published: 2022-10-12
Subjects: Physical Sciences and Mathematics
Rift basins typically comprise three main tectono-stratigraphic stages; pre-, syn-, and post-rift. The syn-rift stage is often characterised by the deposition of asymmetric wedges of growth strata that record differential subsidence caused by active normal faulting. The subsequent post-rift stage is defined by long-wavelength subsidence driven by lithospheric cooling, and is typified by the [...]
The Openscapes Flywheel: A framework for managers to facilitate and scale inclusive Open science practices
Published: 2022-10-10
Subjects: Adult and Continuing Education, Environmental Studies, Remote Sensing
Solutions to large-scale environmental and social challenges require radical collaboration that blends technology and people — and the Open science movement is answering that call by transforming how we work together. While often the focus is on data, publications, code, software developers, and researchers, the transition to Open involves investment across agencies and organizations of all [...]
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 [...]
