Composition and Provenance of Victoria Group Sandstones in Southern North Victoria Land, Antarctica

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
Three distinct source areas contributed to sandstones of the Victoria Group within the Transantarctic Basin in southern North Victoria Land. During the Permian, quartzose sandstones were derived from erosion of the local Ross Orogen, likely from an uplifted swell in the area of today's Ross Sea, the Ross High.

Characterization of refractory aerosol particles collected in the tropical upper troposphere–lower stratosphere (UTLS) within the Asian tropopause aerosol layer (ATAL) [PDF]

open access: yesAtmospheric Chemistry and Physics
Aerosol particles with diameters larger than 40 nm were collected during the flight campaign StratoClim 2017 within the Asian tropopause aerosol layer (ATAL) of the 2017 monsoon anticyclone above the Indian subcontinent.

Imaging the Alpine Collision With Seismic Radial Anisotropy

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The Alpine region and the adjacent Northern Apennines (NA) and Northern Dinarides record the complex tectonic evolution associated with the collision between the Eurasian and Adriatic plates. We combine Rayleigh and Love surface waves from ambient noise and earthquake data recorded at over 3,300 seismic stations to construct a high‐resolution ...

Faults as Volumetric Weak Zones in Reservoir-Scale Hydro-Mechanical Finite Element Models—A Comparison Based on Grid Geometry, Mesh Resolution and Fault Dip

open access: yesEnergies, 2020
An appropriate representation of faults is fundamental for hydro-mechanical reservoir models to obtain robust quantitative insights into the spatial distribution of stress, strain and pore pressure.

Implications of Thermal Weakening and Magma Compressibility for Volcano Monitoring

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Magmatic intrusion and volcanic deformation are traditionally approximated with an inflating cavity in an elastic halfspace. Various analytical models predict surface displacement as a function of pressure or volume change, depth, and elastic crustal properties.

Refining point-cloud neighborhood construction for improved classificationGithubZenodoZenodo

open access: yesScience of Remote Sensing
3D point clouds enable us to capture the structure of our environment in high detail. In the context of urban areas, point clouds allow us to segment single objects, detect changes, and generate detailed maps of highly complex scenes.
