Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we put the journals that publish science from those Divisions at the top of the Highlights section. During this month, we are featuring Natural Hazards (NH), Biogeosciences (BG), and Soil System Science (SSS). They are represented by the journals Geoscientific Model Development (GMD), SOIL, Natural Hazards and Earth System Sciences (NHESS), Earth Surface Dynamics (ESurf), Biogeosciences (BG), Geoscientific Instrumentation, Methods and Data Systems (GI), Nonlinear Processes in Geophysics (NPG), Solid Earth (SE), Earth System Dynamics (ESD), and Hydrology and Earth System Sciences (HESS)
Geoscientific Model Development
Applications of Machine Learning and Artificial Intelligence in Tropospheric Ozone Research – 20 November 2025
Machine learning is being more widely used across environmental and climate science. This work reviews the use of machine learning in tropospheric ozone research, focusing on three main application areas in which significant progress has been made. Common challenges in using machine learning across the three areas are highlighted, and future directions for the field are indicated.
An increase in CO2 in the atmosphere warms the climate through the greenhouse effect, but also leads to uptake of CO2 by the land and ocean. However, the warming is also expected to suppress carbon uptake. If this suppression were strong enough, it could overwhelm the uptake of carbon, leading to a runaway feedback loop causing severe global warming. We find it is possible that this runaway could be relevant in complex climate models and even at the end of the last ice age.
On 13 June 2023, a freestanding rock pillar on the Matterhorn collapsed after years of weakening. Our study examines this progressive destabilization by analyzing field data and integrating lab experiments into a hydro-mechanical model. We highlight the critical role of water infiltration into frozen rock, intensified by climate warming, as a widespread driver of the rising frequency of rockfalls in high mountain permafrost regions.
Representing soil landscapes from digital soil mapping products – helping the map to speak for itself – 21 October 2025
Soil maps are useful for many applications, e.g., hydrology, agriculture, ecology, and civil engineering. The dominant mapping method is Digital Soil Mapping (DSM), which uses training observations and machine-learning to predict per-pixel. Accuracy is assessed by statistical evaluation at known points, but soils occur in spatial patterns. We present methods for helping the map to “speak for itself” to reveal patterns of the soil landscape.
Uncovering the deep structure of the Koillismaa Layered Intrusion Complex, Finland using a novel 3D seismic survey – 20 November 2025
We acquired and processed novel 3D seismic data to reveal the hidden structure of a deep rock formation in northeastern Finland. This study uncovered a complex, layered system rather than a simple magma channel, and identified a major fault that may influence mineral deposits. Our findings offer new tools and insights for exploring valuable underground resources in hard rock environments.
