Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.Abstract Lava tubes are subsurface volcanic conduits formed during effusive basaltic eruptions and are considered key targets for planetary exploration. Orbital remote sensing on the Moon and Mars has identified numerous collapse pits interpreted as possible surface expressions of underlying lava tube systems. However, the limited resolution of current

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.Abstract The cause of the observed mare basalt asymmetry between the lunar nearside and farside remains a long‐lasting conundrum. In this study, we characterized the petrology and geochemistry of the Chang'e‐6 low‐Ti basalts from the lunar farside, performed petrological modeling of major elements and conducted Monte Carlo simulation of trace elements,

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.Abstract Despite the prevalence of rock glaciers in mountain environments, their ice volumes are poorly constrained. Rock glaciers persist in settings unable to support glaciers. They act as climate resilient water stores and refugia for cold‐adapted species while also posing a hazard to alpine communities. Imaging the entire internal structure of rock

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract We investigate the structure and tectonic environment in the crust and upper mantle beneath the North China Craton (NCC) by conducting a full‐waveform inversion of teleseismic P and its coda waves from densely distributed broadband seismic stations. A high‐resolution model involving P‐ and S‐wave velocities as well as density is constructed by

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract The Hangai Dome in central Mongolia represents one of the most prominent intracontinental uplifts, yet the relative contributions of crustal and mantle dynamics in sustaining its high topography remain unresolved. Here we jointly invert Rayleigh wave dispersion and receiver function data to constrain crustal and uppermost mantle structures ...

New views of the spherical Bouguer gravity anomaly [PDF]
Geophysical Journal International, 2004 SUMMARY This paper presents a number of new concepts concerning the gravity anomaly. First, it identifies a distinct difference between a surface (2-D) gravity anomaly (the difference between actual gravity on one surface and normal gravity on another surface) and a solid (3-D) gravity anomaly defined in the fundamental gravimetric equation. Second, it

International Journal of Climatology, Volume 46, Issue 9, July 2026.Monthly average aerosol optical depth at 320 nm obtained with a Brewer MKIII spectrophotometer for Hobart, Australia (42.8806° S, 147.3250° E) over a 21‐year period. There is a linear trend of 15.4% per decade. There are 9 months when the average aerosol optical depth exceeds twice the monthly standard deviation.
