Stratospheric Aerosol From Above: Laser‐Ablation Mass Spectrometer Samples Polar Vortex Air for the First Time

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract The JGR paper by Lawler et al. (2025, https://doi.org/10.1029/2025jd043530) marks a significant and historic first, the PALMS single‐particle chemical analysis sampling deep stratospheric Arctic vortex air for the first time. The analysis finds ∼90% of sulfate aerosol particles in the deepest stratosphere air (100–130 ppb N2O) are meteoric ...

Revealing the Hydrothermal System of La Soufrière Volcano (Guadeloupe) Through Nodal Ambient Noise Tomography

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract La Soufri'ere de Guadeloupe is an active volcano of the Lesser Antilles Volcanic Arc. Its last eruption halted in 1977, yet hydrothermal activity has increased over recent years, raising summit instability hazards. The link between hydrothermal fluids and detachment landslide surfaces is well established and exacerbated by inflation ...

Offshore Freshened Groundwater Distribution Is Controlled by Along‐ and Cross‐Shore Topographic Variability

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Offshore Freshened Groundwater (OFG) reservoirs are regarded as a potentially significant resource stored in continental shelves. While the role of subsurface geological conditions in controlling OFG has been widely recognized, the influence of the topography of the hosting continental shelf on OFG evolution remains poorly understood.

Hydropeaking Catalyzes Redox Reactions in Impacted Aquifers: A First Field Evidence

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Hydropeaking indicates the sudden and frequent fluctuation of river stage caused by the operation of hydropower plants. This river alteration affects numerous physical, chemical, biological, and ecohydrological processes in surface water bodies.

Volatile Conduits Beneath Vulcano Island (Italy) Revealed by High‐Resolution Nodal Local Earthquake Tomography During Volcanic Unrest

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Understanding shallow magmatic and hydrothermal systems at active volcanoes is essential for interpreting unrest and forecasting eruptions. We present the first high‐resolution three‐dimensional Vp $Vp$, Vs $Vs$, and Vp/Vs $Vp/Vs$ models of Vulcano Island, Aeolian Islands, Italy, derived from a dense nodal seismic network.

Deer Antler δ18O Records Desalination in Israel's Water Supply

Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale Stable oxygen isotope ratios (δ¹⁸O) in mammalian tissues are widely used to reconstruct past climates, seasonal patterns, and animal origins. These analyses assume that animals drink local rainwater—an assumption now challenged by large‐scale anthropogenic water management.
