Can a Persistence‐Based Prediction of GRACE Gravity Field Coefficients Reduce Uncertainties at Finer Temporal Scales?

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Enhancing the applicability of Gravity Recovery and Climate Experiment (GRACE) products poses challenges due to the trade‐off between the temporal and the spatial resolution within limits posed by the mission design. If a Kalman filter framework was adopted to characterize the relationship between monthly and finer temporal scales, it could ...

Utilizing NASA's Operation IceBridge Airborne SWE and Precipitation Products to Assess Surface Snow Over Alaskan Glaciers

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Accurately estimating Snow Water Equivalent (SWE) in glacierized regions is critical for glacier modeling and mass balance analysis yet remains challenging due to sparse observations and uncertainties in precipitation products. The objectives are twofold: (a) assess how well three widely used precipitation datasets—Stage IV (a radar–gauge ...

Increasing Frequency of Coastal Erosion Indicated by a Hindcast Model of Storm‐Driven Forcing Calibrated With Beach Stratigraphy

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Beach stratigraphy at North Beach, Sandy Hook, New Jersey is used to calibrate a model of coastal erosion, establish a model‐based erosion threshold, and evaluate how often threshold conditions have been exceeded since 1979 through hindcast analysis.

Teleseismic S‐Wave Coda Autocorrelation and vp/vs ${v}_{p}/{v}_{s}$ Distribution Over the Antarctic Ice Sheet

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Accurate characterization of the compressional to shear (P‐to‐S) wave‐speed ratio (vp/vs ${v}_{p}/{v}_{s}$) within the Antarctic Ice Sheet (AIS) is crucial for understanding its internal structure, mechanical stability, and vulnerability to a changing climate.

Imaging Near‐Surface Bedrock Fracturing and Fluid Pathways Using Seismic Attenuation and Velocity From Viscoacoustic Full‐Waveform Inversion of Refraction Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Seismic attenuation provides sensitivity to fracture density, fluid saturation, and pore geometry that complements velocity, enabling quantitative imaging of fracture architecture and associated fluid‐pathways in near‐surface bedrock. Yet high‐resolution attenuation models remain rare in refraction studies due to amplitude‐fidelity and ...

Multi‐Scale Spatial Variations in Pacific Mantle Seismic Anisotropy: Constraints on Plate Evolution and Asthenospheric Flow

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract We present array‐scale (∼500 × 500 km) anisotropic shear‐velocity models from two Pacific ocean‐bottom seismometer (OBS) arrays of the OBS Research in the Convecting Asthenosphere (ORCA) experiment: Young ORCA (∼43 Ma) and Old ORCA (∼90 Ma). Rayleigh‐wave phase velocities spanning 5–150 s are combined with Love‐wave phase velocities from 5 to ...
