Active hazardous slow faults drive drainage evolution in the Atacama Desert

This is a preprint of manuscript soon to be sumbitted to a peer-review journal. The Atacama Desert of the Central Andean forearc is the driest non-polar region on Earth, where extremely low erosion rates preserve geomorphic markers over Myr timescales. Between 19°S and 20°S, subt...

Atlas of geochemical, petrophysical and mechanical rock properties of the crystalline basement in Germany – first release

Abstract. A comprehensive and statistically robust understanding of rock characteristics is essential for reservoir characterization of the deep subsurface to accurately plan exploration campaigns, parameterize predictive 3D geological models, interpret geophysical data, and exec...

Investigation of glacier mass balance based on multi-source observation in the Karakoram over the past 25 years

The “Karakoram Anomaly” — the atypical stability of glaciers in a warming climate—has introduced considerable uncertainty into projections of regional water resources. However, the resilience of this anomaly under sustained climate forcing remains poorly quantified. In this study...

TIP-INN: A thermodynamics-informed machine learning framework for the mechanical behavior of rocks

Abstract Modeling the mechanical deformation of geological materials across relevant thermodynamic conditions and dynamic processes remains a fundamental challenge in Earth sciences. Conventional rheological models rely on isolated disciplinary approaches and hard-coded iterative...

Integrating smartrock and seismic monitoring to investigate bedload transport dynamics during rapid increase of stages in ephemeral streams

Abstract. Bedload transport dynamics during rapid increases of stage remain poorly constrained, particularly in ephemeral streams where such conditions are common. We combined two cutting-edge monitoring techniques – smartrocks and seismic measurements – to investigate bedload tr...

Gaps in mind: Political and spatial cleavages in local onshore wind attitudes in Germany

Public support for wind energy in Germany is high, yet local opposition can impede project delivery. This study examines which socio-demographic characteristics predict acceptance of onshore wind energy and whether effects differ between urban and rural residents in North Rhine-W...

Conditional updates of neural network weights for increased out of training performance

This study proposes a method to enhance neural network performance when training data and application data are not very similar, e.g., out of distribution problems, as well as pattern and regime shifts. In contrast to previous approaches to out of distribution problems, which alt...

Caysichite-(Y) Ca4(Y,REE)4(Si8O20)(CO3)6·8H2O: Endmember Composition and Structure Established from New Occurrences Across Different Geologic Settings

Abstract The heavy rare earth element silicate-carbonate mineral caysichite-(Y) [Ca4(Y,REE)4(Si8O20)(CO3)6·8H2O] was discovered in the alkaline granite of the Golden Horn Batholith, near Washington Pass, Okanogan County, Washington, USA, as sub-millimeter euhedral orthorhombic pa...

Multi-GNSS clock combination for PPP with an epoch-wise clock alignment and variance component estimation

Abstract Applications of Global Navigation Satellite Systems (GNSS) for positioning, navigation, and timing rely on precise orbit and satellite clock corrections provided by multiple Analysis Centers (ACs) of the International GNSS Service (IGS). To address modeling errors and da...

Uncertainties of GRACE/GRACE-FO Satellite Gravimetry Data and Thereof Derived Products

Abstract Inter-satellite ranging by space gravimetry missions, such as from the Gravity Recovery And Climate Experiment (GRACE) mission and its successor mission GRACE Follow-On, has been established to observe mass variations in the Earth system from space globally. A complex pr...

Multi-time scale analysis of loess landform evolution for Dongzhi tableland, southwestern Loess Plateau, China

Study region Dongzhi tableland, southwestern Loess Plateau, eastern Gansu Province, China. Study focus The loess tableland has shrunk greatly over the past thousand years, and this trend is expected to continue. Predictions of loess tableland evolution can support the design and...

Typhoon‐Driven Near‐Surface Groundwater Dynamics Revealed by Ambient Noise in the Mountain Watershed

Abstract Near‐surface groundwater dynamics (NSGD) regulate water residence time and downstream water resources in mountain watersheds, yet whether a single extreme rainfall event can reorganize near‐surface storage remains unclear. Here, we examine typhoon‐driven NSGD using ambie...

Early Eocene Compressional Deformation in the Northeastern Tibetan Plateau Recorded by Magnetic Fabrics of the Longzhong Basin

Abstract Intracontinental deformation records how early Eocene India–Asia collisional stress propagated into continental interiors. How rapidly compression reached the far field, and whether coeval Paleo‐Pacific slab dynamics contributed, remain debated. The Longzhong Basin, ∼1,9...

Psychotherapy remission prediction models show limited cross-clinic generalizability in routine outpatient care

Abstract Clinical prediction models for psychotherapy outcomes have the potential to assist therapists in planning a patient’s individual treatment, but their clinical utility depends on maintaining predictive performance across settings. We assessed prediction of post-treatment...

Generation and Preservation of Submarine Terraces: Insights From Records Imprinted on the Topography of Dokdo Volcano

Abstract Marine terraces archive sea‐level and tectonic history, yet their relationship to individual highstands remains contentious. While most studies focus on subaerial terraces in uplifting settings, submerged terraces in subsiding settings are less explored. We develop a 1‐D...

Aseismic Slip Along the Evaporite‐Rich Strike‐Slip Katouna‐Stamna Fault in Greece

Abstract Aseismic slip has been observed on many active faults globally, but its controlling mechanisms remain unclear. This study focuses on the NW‐striking, left‐lateral Katouna‐Stamna Fault in Western Greece. We use InSAR surface deformation measurements to confirm the presenc...

Growth rate of the preserved Antarctic continent reveals the anatomy of a late developer

Abstract Ice covers 99.5% of Antarctica. Consequently, its interior geology can only be inferred through subglacial topography and remotely sensed geophysical signatures. We present U-Pb dates, trace elements, and O-Hf isotope data from detrital zircons recovered from scientific...

Station-Based Evaluation of AI Weather Models for Near-Surface Temperature, Pressure, and Wind Forecasts over Eastern Coastal China

Accurate prediction of near-surface meteorological variables is important for weather services and coastal risk management. However, the station-level performance of global artificial intelligence (AI) weather models remains insufficiently characterized in complex coastal environ...

Obtaining Scintrex CG6 Gravimeter Scale Factors with an Uncertainty Below $${1\cdot 10}^{-5}$$ in the Zugspitze Gravimeter Calibration System

Abstract Transportable spring gravimeters have many applications besides exploration geophysics and potential field determination, such as time-lapse measurements in hydrology and volcanology. For maximum accuracy, the time-dependent scale factor of each gravimeter must be determ...

Static friction-coefficient increase in chelating-agent-treated granite saw-cut fractures associated with selective mineral dissolution and void formation

Induced seismicity remains a critical challenge for enhanced geothermal systems (EGS), motivating stimulation strategies that enhance permeability while maintaining fracture stability. Chemical stimulation has been widely studied as a complement to hydraulic stimulation, yet its...
