Imminent Emergence of Permanent Surface Marine Heatwave States Across Global Oceans

Earth's Future, Volume 14, Issue 11, November 2026.
Abstract Marine heatwaves (MHWs) can devastate ocean ecosystems, yet the timing at which anthropogenic changes in MHW characteristics permanently emerge from natural variability at the global scale remains poorly quantified. Here, we present the first global time of emergence analysis of MHW characteristics of the ocean surface using simulations from ...

Extratropical Forcing of Tropical Subsurface Oxygenation Under Future Warming

Global Biogeochemical Cycles, Volume 40, Issue 11, November 2026.
Abstract The global ocean overall is losing oxygen under climate warming, yet most climate models project increasing subsurface (100–1,000 m) oxygen concentrations in the tropical “shadow zones”—poorly ventilated low‐latitude regions of the Indian, eastern Atlantic, and eastern Pacific Oceans.

A Late Cretaceous Aborted Spreading Center in the Northern Arabian Sea Recorded by the Laxmi Basin

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 11, November 2026.
Abstract The Laxmi Basin (LB), a marginal depression, is a prominent geomorphic feature in the northern Arabian Sea. Understanding how the basin formed has important implications for the India–Seychelles breakup and the evolution of the western Indian Ocean.

Co‐Located P and S‐Wave Teleseismic Velocity Tomography of the Alaskan Upper Mantle

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Seismic velocity (V) $(V)$ provides key insights into the structure and thermodynamic state of the Earth's mantle. Leveraging the dense broadband coverage of the Transportable Array (TA) in Alaska, we compiled a data set of 67,671 P $P$‐wave differential travel times and 114,205 multi‐frequency differential travel‐time measurements for S $S ...

Sources and Alterations to Trace Metal Distributions Through the Eastern Canadian Arctic Archipelago and Baffin Bay

Journal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract On its way south to the North Atlantic Ocean, Arctic water of both Atlantic and Pacific origin is modified by sea ice and glacial melt, meteoric water (MW), and continental shelves. In the eastern Canadian Arctic, this modification occurs during transit through Nares Strait, Jones Sound, Barrow Strait, Lancaster Sound, and southward through ...

Variability of Dissolved Oxygen in the Strait of Georgia: Seasonal, Intraseasonal, and Interannual Changes Based on the SalishSeaCast Model

Journal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract Dissolved oxygen (DO) variability in the Salish Sea is driven by circulation, deep‐water renewal (DWR), and biological activity across multiple timescales. Using an updated version of the SalishSeaCast model, we investigate these drivers of DO in its largest basin, the Strait of Georgia, from 2012 to 2020. The model's refined parameterizations

Basin‐Scale Marine Heatwave Types in the Gulf of Mexico: Wind–Humidity Controls on Latent Heat‐Loss Suppression and Ocean‐State Modulation of Vertical Thermal Structure

Journal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract Marine heatwaves (MHWs) in the Gulf of Mexico (GoM) have become more frequent and intense, yet the mechanisms governing basin‐scale events remain incompletely understood. EOF–k‐means clustering of event‐mean sea surface temperature anomalies (SSTA) during 1982–2024 identifies four recurrent, seasonally dependent spatial regimes: two stronger ...

Quiet Time Ionosphere‐Thermosphere Predictability During Sudden Stratospheric Warmings in TIE‐GCM

Space Weather, Volume 24, Issue 11, November 2026.
Abstract We investigate the predictability of the ionosphere‐thermosphere (IT) region during sudden stratospheric warmings (SSWs) by using subseasonal hindcasts in the Community Earth System Model, version 2 with the Whole Atmosphere Community Climate Model (CESM2 [WACCM6]) to force the lower boundary of the TIE‐GCM.

Machine Learning Modeling of Narrow SAID‐Like Spikes in Duskside Subauroral Flows From 11‐Year DMSP Observations

Space Weather, Volume 24, Issue 11, November 2026.
Abstract Subauroral ion drifts (SAID) are narrow, intense westward plasma flows. However, their narrow latitudinal distribution and possible overlap with broader subauroral flows pose significant challenges for accurate modeling. This study proposes a dual‐modal model that takes magnetic latitude, magnetic local time, day of year, solar F10.7 index ...

Dynamic Hydroclimate Fuels Cryptic Sulfur Cycling and Iron and Carbon Impacts in Wetlands

Water Resources Research, Volume 62, Issue 11, November 2026.
Abstract Wetland water quality plays a vital role in controlling emissions of methane, a strong greenhouse gas, and it is regulated by the sequestration of nutrients and toxic metals on iron‐rich soils. However, the stability of these functions under shifting precipitation and temperature regimes remains unknown, because of complex and unconstrained ...
