Geospatial digital mapping of soil organic carbon using machine learning and geostatistical methods in different land uses
Published 2025-02-01“…Abstract Improper management of soil resources leads to the destruction of soil organic carbon (SOC) stock and, as a result, the reduction of soil quality, as well as accelerating the process of climate change through the release of SOC into the atmosphere. This study was conducted to evaluate potential of different simulation models to map the spatial variability of SOC as affected by land use in a study area in Qarasu watershed in Kermanshah province, west of Iran. …”

Geophysical flows over topography, a playground for laboratory experiments
Published 2025-01-01“…Physicists face major challenges in modelling multi-scale phenomena that are observed in geophysical flows (e.g. in the Earth’s oceans and atmosphere, or liquid planetary cores). In particular, complexities arise because geophysical fluids are rotating and subject to density variations, but also because the fluid boundaries have complex geometries (e.g. the ocean floor) with wavelengths ranging from metres to thousands of kilometres. …”
