Tectonic Evolution of the Mariana Trough

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The Mariana Trough is an active back‐arc basin formed by subduction of the Pacific Plate beneath the Philippine Sea Plate and provides an ideal setting for investigating the evolution of back‐arc basins. In this study, we compile bathymetric, magnetic, and gravity data to reconstruct the formation history of the entire basin.

Episodic Change, Quiescence, and Recovery of Earth's Inner Core Surface

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract While a consensus has emerged that the hypothesis of inner core differential rotation cannot provide a consistent explanation for the seismic data, it remains debated whether the seismic data indicate a concurrence of a temporal change of inner core surface with an inner core differential rotation or the temporal change of inner core surface ...

Cambrian Stage 3 Paleomagnetism of the South China Block: Implications for Early Paleozoic Gondwana Reconstructions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The paleogeographic position of the South China Block (SCB) during the early Paleozoic and its affiliation with Gondwana remain debated. We report new high‐quality paleomagnetic data from sandstone‐dominated Cambrian Stage 3 strata correlated with the Yu'anshan–Hongjingshao succession collected along the southwestern margin of the SCB ...

Transition of Glacial Regimes Recorded at IODP Site U1524 in the Ross Sea, Antarctica, Over the Last 800 Thousand Years

Paleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.
Abstract Reconstructing past interactions between the West Antarctic Ice Sheet (WAIS) and changing environmental conditions in the Ross Sea region can help determine long‐term WAIS stability. Existing sedimentary records reveal changes to oceanography, sea ice and ice sheet extent over the glacial‐interglacial cycles of the last ∼800 kyr.

Variation of Global Ionospheric Scintillation and Its Effect on GPS Kinematic PPP‐AR Performance During Geomagnetic Storms in Solar Cycle 25: A Statistical Analysis

Space Weather, Volume 24, Issue 10, October 2026.
Abstract Enhanced small‐scale ionospheric irregularities during geomagnetic storms can disturb Global Navigation Satellite System (GNSS) carrier‐phase tracking and are associated with reduced stability of ambiguity‐fixed precise point positioning (PPP‐AR), but their impact on kinematic positioning remains insufficiently quantified.

Ionospheric Mechanisms Leading to Plasma‐Bubble Zonal Drift Reversal and Deformation During the 12 November 2025 Geomagnetic Storm

Space Weather, Volume 24, Issue 10, October 2026.
Abstract We present a multi‐instrument analysis of the ionospheric response to the intense geomagnetic storm of 12 November 2025 over the American sector, with emphasis on the longitudinally asymmetric deformation, latitudinal expansion, and zonal drift reversal of equatorial plasma bubbles (EPBs).

ScintPi 4.0: A New GNSS‐Based Low‐Cost, Multi‐Constellation, Multi‐Frequency Ionospheric Scintillation and TEC Monitor for Education, Citizen Science, and Research Initiatives

Space Weather, Volume 24, Issue 10, October 2026.
Abstract ScintPi is a series of alternative ionospheric scintillation and total electron content (TEC) monitors. ScintPi monitors have been built by combining single‐board computers (Raspberry Pi) and commercial off‐the‐shelf (COTS) Global Navigation Satellite System (GNSS) receivers.

A Gaussian Process Regression Framework for Slant Ionospheric Delay Interpolation and Uncertainty Quantification With Applications to PPP‐RTK

Space Weather, Volume 24, Issue 10, October 2026.
Abstract Reliable slant ionospheric information is crucial for Precise Point Positioning Real‐time Kinematic (PPP‐RTK), yet its correction in low‐latitude regions remains difficult because of ionospheric variability, observable anomalies, and insufficiently reliable uncertainty characterization.
