Backward swimming in elongated‐bodied abyssal demersal fishes: Synaphobranchidae, Macrouridae, and Ophidiidae

Journal of Fish Biology, Volume 107, Issue 1, Page 52-62, July 2025.
Abstract The deep‐sea demersal fish fauna is characterized by a prevalence of elongated‐body forms with long tapering tails. Using baited camera landers at depths of 4500–6300 m in the Pacific Ocean, we observed multiple instances of backward swimming using reverse undulation of the slender body in four species: the cutthroat eel Ilyophis robinsae ...

Numerical Study on Hydrodynamic Performance of a Pitching Hydrofoil with Chordwise and Spanwise Deformation

Journal of Marine Science and Engineering
The hydrofoil plays a crucial role in tidal current energy (TCE) devices, such as horizontal-axis turbines (HATs), vertical-axis turbines (VATs), and oscillating hydrofoils.

Cloud cavitation with particular attention to pumps [PDF]

, 2008
In many cavitating liquid flows, when the number and concentration of the bubbles exceeds some critical level, the flow becomes unsteady and large clouds of cavitating bubbles are periodically formed and then collapse when convected into regions of ...

Cavity and Wake Flows [PDF]

, 1972
The phenomenon of wake formation behind a body moving through a fluid, and the associated resistance of fluids, must have been one of the oldest experiences of man.

Lacustrine and fan‐delta sediments in syn‐rift lake basins

The Depositional Record, Volume 11, Issue 3, Page 857-892, June 2025.
A consistent model for the sequence framework and depositional pattern of asymmetric half‐grabens in syn‐rift lake basins bounded by active faults has been established, complementing existing models for marine rift successions. Syn‐rift lake basins are characterised by relatively small dimensions, steep slopes, poorly developed shoreline strata ...

Study on the Influence of Chord Length and Frequency of Hydrofoil Device on the Discharge Characteristics of Floating Matter in Raceway Aquaculture

Journal of Marine Science and Engineering
To investigate the influence of the chord length and frequency of an oscillating hydrofoil device on the discharge characteristics of floating particulate matter, in this study, we take raceway aquaculture as an example and systematically compare and ...

Multi‐Year Nutrient and Organic Carbon Mass Balance of a Young Boreal Hydroelectric Reservoir Complex

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 5, May 2025.
Abstract Reservoir construction can alter the transport and export of nutrients and organic matter by rivers to coastal areas. However, influences from construction within the first years after flooding are not well understood. Here we present a 9‐year study of La Romaine Hydroelectric Complex, composed of four cascading boreal reservoirs sequentially ...

Surge Instability on a Cavitating Propeller [PDF]

, 2000
This study details experiments investigating a previously unrecognized surge instability on a cavitating propeller in a water tunnel. The surge instability is explored through visual observation of the cavitation on the propeller blades and in the tip ...

A Tale of Evolution of the Central Indian Tectonic Zone (CITZ) With Glimpses on Pre‐Suture Plate Margin Depositional History

Geological Journal, Volume 60, Issue 2, Page 404-430, February 2025.
Present study explains the current understanding about the complex evolution of the CITZ. New zircon geochronological data from Mahakoshal Basin is used to document the pre‐suture history of the southern margin of Bundelkhand Craton where Mahakoshal Basin developed as a back‐arc basin and remained open even after 1700 Ma.
