Direct Observations of Strong Jets Transporting Deep and Bottom Water Into the Indian Ocean Through the Fracture Zones of the Southwest Indian Ridge

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract The Indian Ocean plays a crucial role in the abyssal overturning circulation, transforming Antarctic Bottom Water (AABW) into lighter water. In the western Indian Ocean, the only path for AABW to reach the subtropics as part of the global overturning is through the fracture zones of the Southwest Indian Ridge.

Tracing Coupled GCM Equatorial Pacific Climatological Biases via Surface Flux Adjustments

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Global weather and climate forecasts hinge on the ability of coupled general circulation models (CGCMs) to simulate ocean‐atmosphere interactions in the tropical Pacific. Yet most CGCMs develop tropical Pacific biases, such as an overly‐intense equatorial cold tongue (ECT), which limit their simulation skill.

Longitudinal Mean Velocity and Turbulent Kinetic Energy Within an Emergent Canopy in Nonuniform Flows

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Vegetation‐induced drag generates nonuniform water surface profiles through flow disruption, creating complex hydrodynamic conditions characterized by enhanced turbulence and energy dissipation. This study investigates the longitudinal velocity and turbulent kinetic energy (TKE) dynamics in emergent canopies under streamwise varying flow ...

A Novel In Situ Experimental Setup for Studying the Impact of Bedform Celerity on 2D Oxygen Distribution in the Hyporheic Zone of Streams

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Hydrodynamic and morphodynamic forces interacting across the sediment‐water interface control the biogeochemistry in the hyporheic zone. When investigating the redox zonation within streambeds, dissolved oxygen (O2) is considered a key solute to the understanding of river ecosystems.

Flow Structures and Their Controls on Downstream Discharge Regulation for a Combined Confluence and Bifurcation Network Node

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract A deep understanding of flow regulation in river bifurcations is critical for downstream river management and flood control. The deltaic river network frequently contains the H‐shaped network node, where two main channels are linked together via a connecting channel, combining both bifurcation and confluence. However, flow structures and their

A Semi‐Analytical Model for Predicting the Depth‐Averaged Maximum Longitudinal Velocity in Fully Ice‐Covered Confluences

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract At river confluences, the complex hydrodynamics result in significant alterations to flow structures, and the maximum velocity zone serves as one of the primary drivers of pollutant transport and riverbed erosion. This study investigates maximum longitudinal velocity formation in fully ice‐covered confluences, statistically validating the ...

Near‐Bed Flow Turbulence Beneath Ice Cover Under Varying Hydrological Conditions: A 9‐Year Field Measurement‐Based Analysis From a Meander Bend

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Climate change alters hydrological and ice conditions, but how these changes affect turbulence beneath ice cover has been poorly studied. This study presents a multi‐year observational analysis of near‐bed turbulence under ice cover in a subarctic meandering river reach.

Kinetic Structure of an Interplanetary Shock Observed at Two Heliocentric Longitudes

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Collisionless shocks convert bulk flow energy into heat, electromagnetic fields, and non‐thermal particle populations. Recent studies suggest that downstream magnetic oscillations could play an important role in ion‐scale energy dissipation at low‐Mach‐number shocks; however, the specific shock and plasma parameters involved remain poorly ...
