First Direct Observations of Dilute Antarctic Turbidity Currents Associated With Dense Water Overflows

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Turbidity currents are increasingly recognised as a key mechanism for transporting sediment into the deep ocean, yet their structure, behavior, and long‐term impact in Antarctic submarine canyons remain poorly understood owing to a lack of direct observations.

Impact of an aerosolized or intramuscular adenovirus type 5-vectored COVID-19 vaccine on Fc-mediated immune effector functions in a hybrid immunity population

Frontiers in Immunology
BackgroundBeyond the role of neutralizing antibodies in protecting against SARS-CoV-2, Fc-mediated antibodies functions may offer additional immune defense.

Near‐Surface Ocean Current and Its Response to Wind Forcing

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Ocean currents near the air‐sea interface are critical for understanding boundary layer processes and advancing coupled models. The near‐surface currents mediate air–sea fluxes and govern the transport of buoyant materials, yet the uppermost meter of the ocean remains sparsely observed and poorly represented in models.

On the Performance of a Horizontally Mounted ADCP in an Energetic Tidal Environment for Floating Tidal Turbine Applications

Sensors
Incident flow measurement is key in the tidal industry for conducting power performance assessments. This paper explores the use of a horizontally mounted Nortek Signature 500 Acoustic Doppler Current Profiler (ADCP) as a means for incident flow ...

Acoustic Detection of Underwater Air Bubbles Generated by Breaking Waves in an Antarctic Polynya

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract The Southern Ocean is a significant sink for anthropogenic CO2 in the atmosphere. The pelagic regions north of sea ice areas primarily absorb atmospheric CO2 via biological productivity and air‐sea gas exchange. The latter is enhanced by the bubbles generated by breaking waves.

Variation of Movable Bed Roughness in the Lower Yellow River Owing to Upstream Damming

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Significant changes in flow‐sediment dynamics and channel evolution have occurred in the Lower Yellow River owing to upstream damming. Notably, the post‐dam stage has witnessed an unexpected increase in movable bed roughness and more frequent dune development, driven by reduced sediment load, coarsened bed material, and altered hydraulic ...

Error Analysis and Correction of ADCP Attitude Dynamics under Platform Swing Conditions

Journal of Marine Science and Engineering
The Acoustic Doppler Current Profiler (ADCP) on a platform generates rotational linear velocity due to dynamic factors in attitude changes, leading to measurement errors in vessel and water flow velocities.

A Hysteresis‐Based Framework for Evaluating and Selecting Streamflow Monitoring Approaches Under Unsteady Gradually Varied Flow Conditions

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Streamflow estimates derived from stage–discharge rating curves (HQRC) inadequately represent the spatiotemporal complexity of unsteady gradually varied flows (UGVF) and are commonly reported without uncertainty, encouraging their treatment as deterministic.

Dune Evanescence at Flood Stage in Lowland Sand‐Bed Rivers: A 2D Modeling Approach With Dynamic Resistance

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Bedforms in lowland sand‐bed rivers, which contribute substantially to total flow resistance, are known to adapt to changing flow conditions. While the growth of subaqueous dunes with increasing bedload transport and their wash‐out at higher transport stages are well documented in laboratory experiments, their possible evanescence in lowland ...

Changes in food‐web pathways and ecosystem functions after sidearm re‐connection in a large river (Danube, Austria)

Restoration Ecology, Volume 34, Issue 7, September 2026.
Abstract Introduction River regulation schemes generally led to changes in riverine assemblage composition and their trophic status, which often is reflected in a general loss or decrease of characteristic species and a concomitant increase or dominance of generalist species.
