Numerical Study of Impact on Submarine Pipeline under the Joint Action of Seabed and Internal Pressure

Shiyou jixie, 2018
In order to study the influence of seabed and internal pressure on the impact of falling object on the pipeline, a finite element model of the impact of falling object on the submarine pipeline is set up by ABAQUS software to analyze the dynamic response

The Staircase Chart: Visualising Vertical and Cross‐Shelf Movements and Dispersal of Early‐Life Fish, Applied to Japanese Jack Mackerel

Fisheries Oceanography, Volume 35, Issue 5, Page 689-703, September 2026.
ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

Using Photographs in Fishers’ Ecological Knowledge Research: A Review and Field Study on Small‐Scale Fishers’ Knowledge of Coastal Habitats in the Central Mediterranean Sea

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Fishers interact daily with coastal environments, which generate a deep understanding of habitat characteristics, species associations and ecological change. Fishers’ ecological knowledge (FEK) is therefore a critical source of insight for marine science, offering observations that uniquely complement scientific data and, when incorporated ...

One‐Shot Multimaterial 3D Printing of a Flexible Spine for a Robotic Fish Prototype

Advanced Intelligent Systems, Volume 8, Issue 8, August 2026.
A one‐shot multimaterial 3D printing approach enables a monolithic soft robotic fish integrating a compliant spine and rigid vertebrae. Electromagnetic linear actuators drive tendon‐based transmission, producing controlled tail oscillations. Finite element modeling and experiments show strong agreement, while optimized material selection improves ...

Impact of an extreme storm event on a multiple intertidal barred coastal system

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Extreme storms do not necessarily cause extreme coastal erosion. Integrated DGPS surveys and SWAN nearshore wave modelling reveal that Storm Barra's peak coincided with a low‐tide stage, allowing multiple intertidal bars (MITBs) to dissipate incoming wave energy before it reached Dundrum Bay's shoreline, highlighting the combined role of tidal stage ...

Mechanism of uplift-induced instability of pipelines in liquefiable seabed under wave loading

Yantu gongcheng xuebao
Variations in the flow field of the surrounding of liquefiable seabed have a significant impact on the dynamic stability of subsea pipelines. The motion of seawater (waves) and the pore fluid within the seabed are described using the Reynolds-Averaged ...

Disrupting the herd: Recreational boating alters group dispersion within beluga whale herds

The Journal of Wildlife Management, Volume 90, Issue 6, August 2026.
Recreational boating in beluga habitat remains poorly documented. Using land‐based observations in the Saguenay Fjord (Quebec, Canada), we show that increasing recreational boat numbers are associated with a higher probability of changes in beluga herd dispersion, suggesting behavioral disturbance and the need to integrate recreational boating into ...

Spatial variability of hydrodynamics in oyster reefs: Investigating the impact of canopy density on mean and turbulent flows

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract This field study investigated how oyster canopy density modulates hydrodynamics of natural intertidal oyster reef. High‐resolution velocity measurements were taken simultaneously within and above oyster canopies of variable density (solid volume fractions, Ø=$$ \mathrm{\O}= $$ 0.04–0.21).

Experimental Study of the Combined Action of Random Waves and Current Induced Hydrodynamics and Seabed Response Around a Protective Three-Dimensional Pipeline

Journal of Marine Science and Engineering
Submarine pipelines serve as the primary transportation infrastructure for offshore energy resources and are becoming increasingly important in modern industrial and domestic applications. A series of laboratory experiments on the dynamic seabed response
