Quantitative analysis of channel characteristics of distributive fluvial systems

Sedimentology, Volume 73, Issue 5, Page 1606-1630, August 2026.
ABSTRACT Distributive fluvial systems (DFSs) are characterised by a radial distributive channel pattern in planform and dominate modern‐day sedimentary basins. Where aggradation occurs, such as in sedimentary basins, there is increased preservation potential, and therefore, DFSs are hypothesised to constitute a significant portion of the continental ...

On the Tropical Nature of an Intense Mediterranean Cyclone in the Ocean‐Atmosphere System

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The Mediterranean basin hosts a large number of cyclones every year. Among them, some rare cases named medicanes present similarities with tropical cyclones but their dynamical characteristics are debated. The ocean‐atmosphere dynamics of Medicane Ianos (2020) are studied here through km‐scale fully coupled ocean‐wave‐atmosphere simulations ...

Tsunami Traveling Ionospheric Disturbances Triggered by the 29 July 2025 Mw 8.8 Kamchatka Earthquake Observed in Japan and Taiwan

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The 29 July 2025 Mw 8.8 Kamchatka earthquake generated notable seismic and tsunami waves. The total electron content (TEC) derived by more than 1,400 ground‐based global navigation satellite system (GNSS) receiving stations in Japan and Taiwan is employed to examine the spatiotemporal evolution of seismic‐ and tsunami‐traveling ionospheric ...

The 2025 Mw 7.6 Aomori Megathrust Earthquake in Northeast Japan: Failure of a Structurally and Rheologically Bounded Asperity Beneath a Cold Mantle Wedge

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract To explore mechanisms of rupture segmentation, we invert coseismic GNSS offsets for the 2025 Mw 7.6 Aomori, Japan earthquake. Our preferred curved‐fault solution images a compact thrust rupture at 25–50 km depth with peak slip ∼2.5 m near 35 km.

Significant Rural Contributions to Severe Coastal Urban Flooding Through Flow Connectivity

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Coastal cities are increasingly threatened by hurricane‐induced compound flooding. However, the relative contributions of rainfall‐surge interactions and other flood drivers, such as runoff from surrounding rural and local impervious areas, in shaping urban flooding remain unclear.

Rapid Morphological Changes in the Intertidal Zone of the Ganges‐Brahmaputra Delta Revealed by SWOT Altimetry Mission

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Intertidal zones of the Ganges‐Brahmaputra (GB) delta are among the most active coastal environments worldwide, and quantifying their morphological evolution remains challenging due to rapid change and scarce in situ observations. This study presents a satellite‐based direct quantification of intertidal sediment volume change in the Meghna ...

Three Decades of Glacial Changes on the Western Antarctic Peninsula Revealed by Historical Aerial and High‐Resolution Satellite Imagery

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The Antarctic Peninsula has been climate‐sensitive since the mid‐20th century, but long‐term glacier mass balance data are scarce. This study uses historical aerial and high‐resolution satellite imagery to estimate mass changes on the western Antarctic Peninsula (66°S $66{}^{\circ}\mathrm{S}$–68°S $68{}^{\circ}\mathrm{S}$) from 1989 to 2020 ...

Assessing Dynamical Contributions to SWOT Sea Surface Height in an Internal Tide Hotspot

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission has revealed high‐frequency sea surface height anomaly (SSHA) variability associated with internal gravity waves, yet comparison with in situ observations remains limited. Here, we analyze a mooring array beneath the swaths of SWOT Cal/Val south of New Caledonia, an internal tide (IT ...

Mesoscale Eddies Reorganize Subsurface Oxygen Minimum Layer in the Subtropical North Atlantic

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Mesoscale eddies play a key role in regulating oceanic physical and biogeochemical environments. However, their influence on vertical oxygen distribution remains poorly constrained by observations. Using 32 years (1993–2024) of in situ oxygen observations from the Bermuda Atlantic Time‐series Study site combined with satellite‐tracked eddies ...

Two Decades of Ross and Weddell Gyre Variability From Observations

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The Weddell and Ross Gyres influence climate‐relevant processes including poleward heat transport, nutrient upwelling and carbon sequestration. However, long‐term tracking of changes to their circulation is limited by the sparsity of observations characteristic of the region.
