Monitoring Near‐Surface Changes Using Anthropogenic Seismic Vibrations

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The abundance of anthropogenic seismic noise provides a valuable resource for monitoring dynamic subsurface property changes. We utilize railway and wind turbine‐induced vibrations recorded by a geophone array to estimate surface wave attenuation and velocity in the underlying glacial deposits of Illinois.

Rapid Evolution of Super Equatorial Plasma Bubbles and X‐Pattern EIA Formation During Extreme Storm Conditions on 12 November 2025

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Extreme conditions during storms profoundly alter the evolution of equatorial plasma bubbles (EPBs), yet the key dynamics remains poorly understood. We document the rapid expansion, contraction, and decay of super EPBs in South America during the 12 November 2025 storm with Interplanetary Magnetic Field (IMF) Bz/By magnitude exceeding ∼50 nT ...

Sub‐Wavelength Seabed Stiffness Control of Seismic Amplitude Modulation in Seafloor DAS

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Submarine distributed acoustic sensing cables record seafloor strain with striking spatial variability whose physical origin is not immediately obvious. By explicitly partitioning the recorded wavefield into ocean‐wave, Scholte‐wave, and teleseismic Rayleigh‐wave components, we show that these amplitude variations are not random but encode ...

Thousand‐Kilometer‐Scale Wavelike Undulations in Ionospheric Plasma Bubble Lifetime and Development Over Wide Longitudes

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The irregularities of ionospheric plasma bubbles (EPBs) sequentially generated over wide longitudes are expected to share similar lifetime under normal conditions. In this study, we report a special case where the EPB irregularity lifetime over wide longitudes showed a quasi‐wavelike undulation pattern with wavelength of ∼3,000 km, that is ...

Observation of Mountain Waves and Secondary Gravity Waves in the Mesosphere Lower Thermosphere Above Patagonia

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract We find observational evidence for mountain waves (MWs) and secondary gravity waves (2GWs) in the OH*(3‐1) layer above Tierra del Fuego, Argentina. On the night of 21–22 May 2018, the Advanced Mesospheric Temperature Mapper (AMTM) obtained temperatures at ∼84 ${\sim} 84$ km.

The Impact of Non‐Orographic Gravity Waves on Transport and Mixing: Effects of Oblique Propagation and Coupling to Turbulence

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Gravity waves (GWs) are a fundamental driver of circulation, tracer transport, and mixing in the middle and upper atmosphere, but their treatment in global circulation models remains incomplete. In particular, standard parameterizations typically restrict propagation to the vertical and treat GW–turbulence interactions in only a rudimentary ...
