Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Geochemical and granulometric fingerprints of 8200 years of westerly wind variability in inner‐fjord lake sediments from Svalbard

Boreas, EarlyView.
The Arctic is warming faster than any other region on Earth. As sea ice diminishes, the surface boundary conditions, such as roughness and air–sea coupling, change and open‐water fetch increases. This may enhance wind forcing on Arctic coasts. Lake sediments can record these changes through the deposition of wind‐blown grains and elements, offering ...

Weathering the Storm: Effects of a Hurricane‐Induced Thermal Disturbance on a Juvenile Atlantic Halibut (Hippoglossus hippoglossus) Hotspot in Nova Scotia, Canada

Fisheries Oceanography, EarlyView.
ABSTRACT Atlantic Halibut has recently become the most valuable groundfish in Atlantic Canada following population recovery, and the benthic habitat characteristics of their aggregation areas have been identified as a key outstanding ecological knowledge gap for the species. In 2022, during a multi‐year acoustic tracking study in a key juvenile hotspot

An analysis of mass balance and fractional particle size distributions of coal and magnetite in a dense-medium cyclone circuit

, 2009
In this study, a complete mass balance of magnetite and coal in the various parts of a dense-medium cyclone (DMC) circuit was determined and fractional size distributions of magnetite and coal were analyzed for the circuit.

Impact of an Environmental Index of Recruitment on the Stock Assessment for Petrale Sole (Eopsetta jordani Lockington, 1878) in the California Current Ecosystem

Fisheries Oceanography, EarlyView.
ABSTRACT Stock assessments provide key scientific input for managing fisheries. Age‐structure information is important for these assessments because it provides the foundation for estimating recruitment, which impacts estimates of future spawning biomass and other assessment parameters that inform management.

Rubble stabilization alone cannot overcome the deleterious effects of soft coral dominance

Restoration Ecology, EarlyView.
Abstract Introduction Without intervention, the material legacies of smashed coral—loose rubble—can persist on reefs for decades and impede coral recruitment. Stabilizing interventions that accelerate rubble binding processes and foster coral growth and survival are commonly tested across narrow methodological, spatial, and temporal scales.

On the Identification and Tracking of Mesoscale Convective Systems Over Southern Africa

Geoscience Data Journal, Volume 14, Issue 1, January 2027.
Automated algorithms used for the detection and tracking of mesoscale convective systems (MCSs) inadvertently track non‐MCSs, such as tropical cyclones and cold fronts. A new approach here, based on quantifying the cold cloud shield compactness of a tracked feature, is used to remove these non‐MCSs from the MCS database over southern Africa.

Using Small Unoccupied Aerial System (sUAS) Multispectral Imagery to Compare Hydrodynamics Around Different Aged Patches of Marsh Vegetation

Ecohydrology, Volume 19, Issue 7, November/December 2026.
ABSTRACT Wetland vegetation influences water and sediment transport by altering flow resistance. Vegetation presence, stem density, leaf and stem morphology, and flexibility, among other characteristics, control the degree to which vegetation impacts transport patterns.

Integrating Meteorological Data for Drought Prediction: A Hybrid Ensemble Machine Learning Approach in Northwestern Bangladesh

Public Health Challenges, Volume 5, Issue 4, December 2026.
This study presents a hybrid weighted average ensemble model (GBM + RF + XGBoost) for 7‐day‐ahead SPEI drought forecasting in Dinajpur, Bangladesh. Among individual models, GBM performed best (RMSE = 0.0059, R2 = 0.9999, NSE = 0.9999), followed by random forest (RMSE = 0.0079) and XGBoost (RMSE = 0.0141).
