Shaking‐Induced Small Seismic Velocity Changes as Revealed From Seismic Interferometry Analysis of Distributed Acoustic Sensing Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Understanding the spatio‐temporal variations in the physical properties of the Earth's crust is crucial for comprehending the dynamic processes linked to earthquakes. Conventional seismometer‐based analyses have limitations in spatio‐temporal resolution due to the sparse station distribution.

The Role of Time‐ and Spatially Varying Wind in Coastal Circulation Based on High‐Resolution Oceanic and Atmospheric Simulations

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Wind forcing plays a central role in oceanic circulation, including circulation in small bays where complex coastal orography modulates local winds both in time and space. However, their role in the circulation of such bays remains unclear because local winds are difficult to observe directly over the sea. Here, we used oceanic and atmospheric

Tropical Bee Assemblage Diversity Decreases With Elevation While Body Size Increases

Biotropica, Volume 58, Issue 4, July 2026.
Photos of bee specimens collected in the Colombian Andes across a nearly 3000 m elevational cline. They are arranged to illustrate both the decline in richness with elevation and the increase in community average body size with elevation. ABSTRACT Elevation gradients are powerful drivers of changes in species composition, richness, and functional ...

InSAR Digital Surface Model Refinement by Block Adjustment with Horizontal Constraints [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Interferometric Synthetic Aperture Radar (InSAR) technology is an important method to generate digital surface model (DSM). The past studies on space-borne derived DSM most focused on the elevation correction, due to the relative low resolution of DSM ...
