Computer vision-based measurement of stormwater discharge: proof-of-concept
Published: 2025-01-29
Subjects: Civil and Environmental Engineering
Stormwater systems, as infrastructure draining urban water runoff into water bodies, are pivotal in preserving municipal functionality while they play an important hydrological and environmental role. As such, the ability to reliably monitor stormwater outflow in many locations could provide valuable information for water managers. However, in most cases stormwater outlets have not been designed [...]
Large earthquakes are more predictable than smaller ones
Published: 2025-01-29
Subjects: Geophysics and Seismology, Physical Sciences and Mathematics
Large earthquakes have been viewed as highly chaotic events regardless of their magnitude, making their prediction intrinsically challenging. Here, we develop a mathematical tool to incorporate multiscale physics, capable of describing both deterministic and chaotic systems, to model earthquake rupture. Our findings suggest that the chaotic behavior of seismic dynamics, that is, its sensitivity [...]
Implicit-tuning signal quantified through a tri-experiment design in a legacy spectral GCM
Published: 2026-06-14
Subjects: Atmospheric Sciences, Climate, Numerical Analysis and Scientific Computing
We quantify the climate response of the MGO atmospheric general circulation model (MGO-03 T42L25) to two alternative implementations of a structural fix in the vertical-exchange parameterization. A companion parallelization study (under review) identifies an unintended inter-latitude state leakage through SAVE-persistent working arrays in the boundary-layer scheme. Here we contrast the legacy [...]

Removal of Cd (II) and Zn (II) ions from Aqueous Solutions using Carbonized and Functionalized Persea americana Root Stem Powder
Published: 2025-01-30
Subjects: Environmental Sciences
The ability of carbonized and modified avocado (Persea americana) root stem powder (C-PA and M-PA) to remediate Cadmium (Cd (II)) and Zinc (Zn (II)) contamination in aqueous solution was studied by varying the carbonization temperature, particle size of the adsorbent, adsorption temperature, pH of the solution, contact time, adsorbent dose and adsorbate concentration. Scanning electron microscopy [...]
Insights into plume-ridge-transform fault interactions as derived from 3D numerical geodynamic modelling of the Azores Triple Junction
Published: 2025-01-31
Subjects: Geology, Tectonics and Structure
The Azores Archipelago is an igneous province located in the centre of the Atlantic Ocean marked by a large bathymetric plateau with a complex tectonic history. Over the last 10 Myr, this region has been shaped by the interaction between the Azores plume, the Mid-Atlantic Ridge (MAR), and the Gloria Fault zone. This complex interaction was characterised namely by the transition from a [...]
An Irish female pioneer in geology: Mary Katherine Andrews (1852 - 1914)
Published: 2024-12-18
Subjects: Physical Sciences and Mathematics
Mary Katherine Andrews (1852–1914) was a woman of her time, a Victorian then Edwardian lady interested in science. Raised in an academic household in Belfast, she did not have the opportunity to attend university, because women were not accepted when she was young. This did not discourage her in developing her scientific interests, and she became an accomplished amateur geologist. The quality of [...]
Quantifying Changes in Water Loading in the U.S. Southwest via Comparison of GNSS, GRACE, and SWE Datasets
Published: 2025-01-31
Subjects: Geophysics and Seismology, Hydrology
The synthesis of Gravity Recovery and Climate Experiment (GRACE) gravimetry data and Global Navigation Satellite System (GNSS) displacement data provides improved models of surface water hydrology. Much work remains to be done to understand the hydrological signal present in complementary geodetic data in much of the Western U.S., especially the Colorado River basin which comprises a diversity of [...]
Advancing forest disturbance economics – assessing the impacts on timberland returns requires consistent economic approaches
Published: 2025-01-31
Subjects: Forest Sciences
The discussion about economically optimal forest ecosystem management is almost as old as forest science. Continuous cover forestry renounces removing the tree canopy of forest ecosystems. In contrast, clear fell forestry suggests harvesting all trees at once to replace the crop trees with young trees. Assuming occurrence probabilities for stands of different ages, a study by Kärenlampi [...]
Natural Hydrogen Development-Potential and Challenges
Published: 2025-01-31
Subjects: Earth Sciences
Natural hydrogen has recently been identified as a potential source for future energy systems. This paper investigates the technical development potential of natural hydrogen by estimating, for some recent finds and identified prospects, in-place and recoverable hydrogen, well productivity, water production and other byproducts that a future development would have to cater for. Finds are in three [...]
Steady crevasse location in Pâkitsoq, Greenland over one decade: Results from MimiNet, a new deep-learning model for crevasse detection
Published: 2025-07-03
Subjects: Physical Sciences and Mathematics
If crevasse fields deliver meltwater to the bed of the Greenland Ice Sheet, it would affect seasonal ice flow speeds and total mass balance. The best current automated tool to map crevasse fields extends only a few dozen kilometers inland. To address this gap, we develop MimiNet, a neural-network-based tool that identifies surface crevasse fields. We train MimiNet on Sentinel-1 scenes across a [...]
Cross-equatorial northerly surges associated with extratropical cold surges and tropical variability over the Maritime Continent
Published: 2025-01-31
Subjects: Physical Sciences and Mathematics
Cross-equatorial northerly surge (CENS) is characterized by a strengthening of northerly moist monsoon winds over south of the South China Sea in the western Maritime Continent. The CENS typically lasts a few days in boreal winter and is frequently reported as a crucial synoptic forcing of heavy rainfall and flood events over northern Java Island. The occurrence of CENS has been generally [...]
Feasibility of Time-Lapse Surface Seismic for CO2 Monitoring: A Case Study from the Decatur CCS Site, Illinois, United States
Published: 2025-01-31
Subjects: Physical Sciences and Mathematics
We study the feasibility of time-lapse surface seismic to detect and monitor CO2 plume movement over the time at the onshore Decatur CCS site, United States. We develop and test a workflow, integrating results from subsurface characterization, dynamic flow simulation, rock physics, time-lapse fluid saturation logs, and operational information to model surface seismic responses of the [...]
