Eddy Kinetic Energy Variability From 30 Years of Altimetry in the Mediterranean Sea

Ocean Science
Abstract. Mesoscale activity plays a central role in ocean variability, substantially influencing the mixing of biogeophysical tracers, such as heat and carbon, and driving changes in ecosystems. Eddy Kinetic Energy (EKE), a metric used for studying the intensity of mesoscale processes, has recently been shown to increase in regions of intense EKE ...

Baroclinic Submesoscale Eddies in the Ross Ice Shelf Cavity Alter Heat Pathways to the Ice Base

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The influence of baroclinic submesoscale eddies on basal melting beneath Ross Ice Shelf remains poorly understood. We analyzed a 4.5‐year mooring record from the central cavity and identified seven eddy‐like events from variability in density, velocity, and thermohaline structure, with horizontal scales (∼11 km) characteristic of submesoscale ...

Oceanic Spatio‐Temporal Patterns of Vertical Velocities in the Cape Basin and Agulhas Current Retroflection From Two Years of SWOT Altimetry

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The Surface Water and Ocean Topography (SWOT) satellite provides a groundbreaking view of sea surface height (SSH) across a 120‐km‐wide swath (20‐km nadir gap), opening new opportunities to reconstruct vertical velocities (w) $(w)$. Vertical motions play a central role in redistributing properties, influencing climate and ecosystems. Using the

Understanding Drought‐Induced Soil Moisture Feedback on Atmospheric Circulation: Observations and Simulation Experiments of the 2020 Western U.S. Drought

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract This study examines the large‐scale atmospheric response to reduced evapotranspiration during droughts in the Western U.S., using an observation‐based regression method and numerical experiments with a global climate model. We found that Western U.S.

GNSS Zenith Wet Delay as a Boundary Layer Diagnostic: Regime‐Dependent Turbulence Signatures From Large Eddy Simulation and Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Global Navigation Satellite Systems (GNSS) provide continuous measurements of zenith wet delay (ZWD), reflecting column‐integrated atmospheric water vapor. While the slowly varying ZWD is routinely assimilated in numerical weather prediction, the rapid fluctuations on timescales of seconds to minutes that arise from boundary‐layer turbulence ...

Thermal and Photocatalytic Conversion of CO2 to Ethanol: Advances in Catalyst Design, Challenges, and Opportunities

ChemSusChem, Volume 19, Issue 12, 26 June 2026.
This review examines thermo‐ and photocatalytic routes for converting CO2 to ethanol and analyzes how metal alloying, promoters, supports, surface structure, and semiconductor design govern catalyst activity, selectivity, and stability. It integrates mechanistic insights from experimental and theoretical studies and identifies the main challenges and ...

Gold(I)‐Mediated Reactivity of Allenes With Mesoionic Nucleophiles: A Computational Exploration

European Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.
The regioselective gold(I)‐mediated reactivity of allenes with mesoionic nucleophiles has been evaluated through computational analysis of the mechanisms involved. Instead of typical (3 + 2) pathways, sydnones and münchnones favour the formal (3 + 3) cyclizations affording substituted dihydropyridines.

Multimethod Microstructural Diagnostics of Polymer Electrolyte Membrane Water Electrolysis Cell Components Uncovering Diverging Degradation Pathways After Short‐Term Testing

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
This study probes why polymer electrolyte membrane electrolyzers lose efficiency under different operating profiles. Using electrical tests, microscopy, and spectroscopy, Ti‐PTL passivation is established as the dominant cause for increased Ohmic resistance in samples aged under constant and triangular current profiles for 88 h.
