Holocene palaeoenvironmental reconstruction of sea level, coastal and vegetation changes along the southern Solway Firth, United Kingdom

Journal of Quaternary Science, Volume 41, Issue 3, Page 419-432, April 2026.
ABSTRACT Holocene relative sea level (RSL) changes were reconstructed from four sites along the less‐studied southern Solway Firth. A multiproxy approach, including lithostratigraphical and biostratigraphical analyses, combined with radiocarbon dating, produced ten sea level index points (SLIPs).

Dataset of Quiet Space Weather Periods for Ionospheric Studies

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract The ionosphere is a dynamic environment regularly affected from above and from below. This study identifies periods within the years 2000–2023 when the impact from above, driven by space weather, was minimal. The quiet space weather periods have wide usage for two types of ionospheric studies. At first, studies of isolated space weather events

The Development of a Low Power GNSS System, as Part of a Drone Assisted Environmental Sensor Network for a Glacial Environment

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract We show the development of an innovative Internet of Things Real Time Kinematic Global Navigation Satellite System, to study the short‐term changes in surface velocity of two adjacent Icelandic glaciers, in order to understand the response of glaciers to climate change.

Assessing Structure Collapse and Vegetation Loss After the 2025 Eaton Fire Using Optical Remote Sensing

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract On 7–8 January, 2025, the Eaton fire destroyed >9,000 structures and >40 km2 of forest in the northeastern region of the Los Angeles metropolitan area, California. Building damage was primarily assessed through ground investigations, a process that took several weeks due to hazardous conditions and the difficulty of accessing burnt areas. This

Tracking Deep Magma Migration Through Diffuse CO2 Degassing: Insights From Piton de la Fournaise Volcano (2013–2023)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract Volcano monitoring requires identifying and distinguishing physico‐chemical processes at various depths within magma plumbing systems and their links to volcanic activity. Long‐term monitoring of deep magma reservoirs, extending down to tens of kilometers, is crucial even though signals from these depths are often altered or attenuated before ...

Imprint of the Quasi‐Biennial Oscillation on the Ionosphere and Thermosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The Quasi‐Biennial Oscillation (QBO) is a dominant mode of stratospheric variability and is known to modulate the variability of the ionosphere‐thermosphere (IT) system. However, the extent of its influence on the ionosphere‐thermosphere system remains uncertain due to weak signals and confounding with similar periodicities in solar flux.

Global Ionospheric TEC Variability: Long‐Term Spectral–Wavelet Analysis and Geomagnetic Storm Event Case Studies

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract This study investigates global ionospheric variability using Global Total Electron Content (GTEC), defined as the spatial average of daily averaged Global Ionospheric Maps derived from the International GNSS Service. The analysis spans from 2010 to 2024, covering Solar Cycle 24 and the rising phase of Solar Cycle 25, and incorporates ...

Holocene Normal Faulting in the Southern Rocky Mountain Trench; Orogenic Collapse Modulated by Glacial Unloading?

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Southern Rocky Mountain Trench (SRMT) is a conspicuous valley in the eastern Canadian Cordillera. It lies above a sharp change in lithospheric strength and thickness and is occupied by a normal fault thought to have last been active in the Eocene.

A Hybrid Probabilistic Framework for Mixed Discrete–Continuous Subsurface Parameter Estimation From Multi‐Physics Geophysical Data: A Case Study for Quantifying the Geofluid Mapping in the Crust and Upper Mantle

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Joint estimation of discrete (e.g., lithology or geofluid type) and continuous (e.g., porosity, pore geometry, related connectivity) subsurface parameters represents a challenging inverse problem due to strong parameter trade‐offs, effective non‐uniqueness, and multi‐modal posterior structures.

Cost-Efficient Multi-GNSS Station with Real-Time Transmission for Geodynamics Applications

Remote Sensing
GNSS is a standard tool for monitoring and studying the Earth’s dynamic environment. However, the development of dense GNSS measurements remains limited in many experiments by the cost of high-class geodetic equipment to achieve the high precision ...
