Spatial and Temporal Variability in Tide‐Induced Icequake Activity at the Astrolabe Coastal Glacier, East Antarctica

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 8, August 2025.
Abstract The grounding zones (GZ) of marine‐terminating glaciers, where ice transitions from grounded to floating, experience strong mechanical changes in response to ocean tides. The spatial and temporal dynamics of these changes remain poorly documented, as they require multi‐scale observations capable of resolving internal ice deformation.

The application of Skylab altimetry to marine geoid determination [PDF]

The author had identified the following significant results. The major results can be divided broadly into two groups. One group is concerned with the effects of errors inherent in the various input data, such as the orbit emphemeris, a priori geoid etc.

Shrub Expansion Can Counteract Carbon Losses From Warming Tundra

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 8, August 2025.
Abstract Arctic warming is causing substantial compositional, structural, and functional changes in tundra vegetation including shrub and tree‐line expansion and densification. However, predicting the carbon trajectories of the changing Arctic is challenging due to interacting feedbacks between vegetation composition and structure, and surface ...

Geodetic analysis of Skylab altimetry preliminary data - SL/2 EREP pass 9 [PDF]

The author has identified the following significant results. The analysis was based on a time series intrinsic relationship between the satellite ephemeris, altimeter measured ranges, and the corresponding a priori values of subsatellite geoidal heights.

Probabilistic Assessment of the Causes of Active Deformation in Greece, Western Anatolia, and the Balkans Using Finite Element Models

Tectonics, Volume 44, Issue 8, August 2025.
Abstract We constrain the contribution of driving and resistive regional forces to the observed surface deformation in the Nubia‐Eurasia plate boundary region. We use a viscoelastic mechanical model with fault zones representing regional active faults. Deformation is driven by velocities of surrounding plates and by lateral variations in gravitational ...

Deciphering Pleistocene Fault Activity in the Eastern Alps: Dating Fault Gouges With Electron Spin Resonance and Optically Stimulated Luminescence

Tectonics, Volume 44, Issue 8, August 2025.
Abstract The Eastern Alps have been influenced by post‐collisional indentation tectonics since the Miocene. Currently, Adria‐Europe convergence, albeit slow, is accommodated and distributed across several faults. The seismogenic potential of some of these faults is unclear. We applied optically stimulated luminescence (OSL) and electron spin resonance (

A Gravity Study of the Crustal Structure Beneath the Young Amagmatic Rukwa‐Tanganyika Rift Zone

Tectonics, Volume 44, Issue 8, August 2025.
Abstract The Rukwa‐Tanganyika Rift Zone (RTRZ), experiencing multiphase rifting, forms the nonvolcanic southern part of the Western Branch of the East African Rift. We investigate the crustal structure beneath the RTRZ to understand how strain migrates beneath multiphase rifts.
