Head and Whisker Behaviours Observed During Foraging in Northern Elephant Seals (Mirounga angustirostris)

Ecology and Evolution, Volume 16, Issue 5, May 2026.
We observed a range of behaviours during foraging, including forward swimming, vertical diving, swooping, dabbing, sweeping and rotations. Head dabbing was also sometimes accompanied by the seal producing infrasounds, the bouts of which coincided with rhythmic whisker protractions. ABSTRACT Pinnipeds use their whiskers to detect and follow hydrodynamic

UAS‐Based Observations of Infrasound Directionality at Stromboli Volcano, Italy

Geophysical Research Letters, 2023
Infrasound (low frequency sound waves) can be used to monitor and characterize volcanic eruptions. However, infrasound sensors are usually placed on the ground, thus providing a limited sampling of the acoustic radiation pattern that can bias source size

Effects of Discharge and Morphology on Fluvial Sound

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Toward developing acoustic monitoring for stream gauging applications, we show the dependence of stream sounds on discharge and morphology in field and lab studies. Currently, there is need for innovative, non‐invasive, and low‐cost methods of surface freshwater discharge monitoring, and recording aerial fluvial sounds could be used ...

An Analysis of Dense Seismoacoustic Signals from an Accidental Chemical Explosion in South Korea on 4 March 2020

The Seismic Record
On 4 March 2020, an accidental explosion occurred at a chemical plant in South Korea, generating both seismic and infrasound signals, which were recorded by multiple sensors at distances as great as 400 km across the southern Korean Peninsula.

An Easy Method to Sample Headspace Pheromones in the Field

Ethology, Volume 132, Issue 5, Page 365-371, May 2026.
Females of the orb‐web spider Argiope bruennichi produces a pheromone to attract males for mating. Most of our knowledge about the pheromone and its strategical use by the females is known from the laboratory. While we have confidence in the validity of these results, we wanted to make sure and measure pheromones in the field.

Reconstructing surface eruptive sequence of 2018 small phreatic eruption of Iwo-yama volcano, Kirishima Volcanic Complex, Japan, by infrasound cross-correlation analysis

Earth, Planets and Space, 2021
The Iwo-yama volcano of the Kirishima Volcanic Complex in Japan had a small phreatic eruption in April 2018, which newly formed multiple vents. The activity was recorded by two infrasound sensors and two monitoring cameras, which had been installed ...

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

The Anatomical Record, Volume 309, Issue 4, Page 912-929, April 2026.
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

OH Airglow for Ionospheric Seismology Applications—From Instrumental Noise Characterization to Rayleigh Waves Detection Threshold

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Airglow layers are powerful tracers of upper‐atmosphere dynamics because of their sensitivity to a broad spectrum of atmospheric wave phenomena. Seismic activity, and in particular Rayleigh waves, constitutes a forcing mechanism capable of generating infrasonic waves in the atmosphere.

Characterization and Localization of Chemical Explosions and Lightning Flashes by a Flotilla of Stratospheric Balloons

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract On 3 August 2021, a flotilla of four Heliotrope solar hot air balloons was launched from central New Mexico (USA). The balloons, equipped with microbarometers, flew from sunrise to sunset at altitudes between 17 and 22 km. During the flight, eight chemical explosions ranging from 45 to 136 kg TNT equivalent and a thunderstorm occurred in the ...

Listening to the Atmosphere: Using Infrasound Observations to Infer Atmospheric Conditions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract The stratosphere and mesosphere are important regions for the prediction of weather at the Earth's surface for medium‐ and long‐range forecasts. The availability of observations in these layers is lower than that of the troposphere, especially for the dynamics. While seeking new observational sources is important, there are existing infrasound
