Westerly winds prompted an anomalous southward migration of Pacific saury (Cololabis saira)

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract The Pacific saury (Cololabis saira), a key pelagic fish in the Northwest Pacific, exhibits autumn migration modulated by Kuroshio–Oyashio Extension mesoscale features, yet daily fishing ground variability remains unexplained. Traditional reliance on remote sensing data has limited understanding of the three‐dimensional mechanisms governing the

Preliminary Performance Assessment of the Wave Parameter Retrieval Algorithm from the Average Reflected Pulse

Remote Sensing
To obtain new information about surface waves, it is proposed to use an underwater acoustic wave gauge, and an assessment of its effectiveness can be performed using a numerical simulation and field experiment.

Applications of MST radars: Meteorological applications [PDF]

Applications of mesosphere stratosphere troposphere radar to mesoscale meteorology are discussed. The applications include using the radar either as a research tool to improve our understanding of certain dynamical systems or as part of a network used to

Evolution of secondary cellular circulation flow above submarine bedforms imaged by remote sensing techniques [PDF]

, 2013
Normalized radar cross section (NRCS) modulation and acoustic Doppler current profiler (ADCP) measurements above submarine sand ribbons and sand waves are presented. The two study areas are located in the Southern Bight of the North Sea at the Birkenfels

Finding the Best Nursery: How Habitat Features Shape Juvenile Snapper (Chrysophrys auratus) Density

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
This study examines habitat preferences of juvenile Australasian snapper (Chrysophrys auratus) in northeastern New Zealand, analysing data from 113 stations across structured and unstructured habitats. We investigated how juvenile snapper densities were influenced by environmental factors, including prey availability and physical habitat features ...

The Frequency Response of Acoustic Doppler Current Profilers

, 2014
The lifespan of a tidal turbine is strongly affected by the unsteady loading it experiences, so knowledge of the mean flow speed is not sufficient: unsteadiness must also be quantified. One of the most common turbulence measurement devices in the marine environment is the Acoustic Doppler Current Profiler (ADCP).

Diagnostic Accuracy of O‐RADS US, IOTA Simple Rules, Subjective Assessment, and the Sequential IOTA Simple Rules–Subjective Assessment (SR–SA) Strategy in Adnexal Masses: High Sensitivity Versus the Challenge of Specificity in a Middle‐Resource Setting

Sonography, Volume 13, Issue 1, March 2026.
ABSTRACT Objectives To compare four ultrasound models: O‐RADS US, IOTA Simple Rules (SR), Subjective Assessment (SA), and the Sequential SR–Subjective Assessment strategy (SR–SA) for classifying adnexal masses and to assess whether additional discrimination is possible within intermediate‐risk O‐RADS 3 lesions in a middle‐resource setting.

Anatomical Study and CT Scan of the Scleral Ring in the Little Owl (Athene noctua)

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
The scleral ring in Athene noctua predominantly consists of 15 quadrilateral ossicles, with a rare anatomical variation of 16 ossicles observed unilaterally in one specimen. Structural Morphology: The ring displays a distinct bipartite architecture, featuring an anterior tubular segment with a near‐circular cross‐section and a posterior funnel‐shaped ...

Glacier‐Atmosphere Interactions and Feedbacks in High‐Mountain Regions ‐ A Review

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Mountain glaciers are among the natural systems most vulnerable to climate change. However, their interactions with the atmosphere are complex and not fully understood. These interactions can trigger rapid adjustments and climate feedbacks that either amplify or attenuate atmospheric signals, influencing both glacier response and large‐scale ...
