Performance Investigation of Four Ionospheric Models in Estimating hmF2 in High‐Latitude Regions
Space Weather, Volume 24, Issue 7, July 2026.Abstract As a critical parameter characterizing the vertical structure of the ionosphere, the peak height of the F2 layer (hmF2) plays an essential role in frequency selection and signal propagation in high‐frequency (HF) communication systems. Accurate prediction of hmF2 is particularly important in high‐latitude regions.

Adaptive Acoustic Monitoring for Endangered Cook Inlet Beluga Whales in Complex Soundscapes
Marine Mammal Science, Volume 42, Issue 3, July 2026.ABSTRACT Effective conservation of the endangered Cook Inlet beluga whale (Delphinapterus leucas) requires comprehensive spatiotemporal data, yet monitoring efforts remain spatially biased, underrepresenting important southern habitats. Passive acoustic monitoring (PAM) provides the necessary broad‐scale coverage, but its expansion introduces ...

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Low frequency sound can travel great distances in planetary atmospheres. When these waves reflect off the air/ground interface, energy may be absorbed or transferred to mechanical waves in the subsurface. This study describes the direct and reflected acoustic wave generated by the re‐entry of the OSIRIS‐REx Sample Return Capsule captured on a ...

Thermal Structure Beneath the Himalayan Orogen Revealed by Pn‐Wave Receiver Function Imaging
Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract The Himalayan orogen formed through convergence between the Indian and Eurasian plates, and parts of the subducting Indian crust were impeded by the Lhasa terrane and accreted into the orogen. However, whether the Indian lower crust was stripped from the downgoing plate and incorporated into the orogen, and by what mechanism, remain debated ...

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract The large‐scale traveling ionospheric disturbances (LSTIDs) over the Asian‐Pacific sector during the 10–11 May 2024 superstorm are investigated using ionosonde observation and simulation from a whole geospace model—Multiscale Atmosphere Geospace Environment (MAGE), which fully couples multiple magnetosphere, ionosphere and thermosphere models.
