Wave-induced residual response and liquefaction of a nonhomogeneous layered seabed

Frontiers in Marine Science
Numerical studies were conducted on the wave-induced residual liquefaction of a silt–coarse sand layered seabed. Fully dynamic soil equations and residual seabed response equations were incorporated into the development of a numerical model.

Dynamic Response of Seabed Around Suction Anchor

PROCEEDINGS OF CIVIL ENGINEERING IN THE OCEAN, 1994
The frequency response of seabed around a suction anchor subjected to a mooring force of floating structure is numerically evaluated by taking the seabed characteristics into consideration. The seabed is assumed to be a fluid-saturated poroelastic medium whose behavior is governed by Biot's theory of wave propagation, and the suction anchor is modeled ...

Electrically responsive knitted liquid crystal elastomer actuators for underwater applications

Responsive Materials, EarlyView.
A knitted liquid crystal elastomer‐liquid metal (LM) actuator enables electrically driven soft robotics in water. Core–shell fibers are melt‐spun, knitted, and infused with LM to combine internal conductivity, external insulation, and programmable textile deformation.

The Influence of Shell-Sand Mixing on the Dynamic Response of the Seabed Foundation in Front of a Slope Breakwater

Journal of Marine Science and Engineering
Shell-sand mixing, as a novel technique for coastal protection and seabed improvement, holds broad application prospects. However, the underlying mechanism of its influence on the wave-induced dynamic response of the seabed beneath slope breakwaters ...

Two-Dimensional Numerical Study of Seabed Response around a Buried Pipeline under Wave and Current Loading

Journal of Marine Science and Engineering, 2019
The evaluation of the wave-induced seabed response around a buried pipeline has been widely studied. However, the analysis of seabed response around marine structures under the wave and current loadings are still limited.

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

Scalable low‐cost seabed landers: the missing link for sustained, integrated, long‐term observations in dynamic shallow seas

Remote Sensing in Ecology and Conservation, EarlyView.
Seabed landers, when equipped with a range of biotic and abiotic sensors, offer a non‐invasive and cost‐effective solution for ecosystem‐scale monitoring of Essential Biodiversity Variables (EBVs) and Essential Ocean Variables (EOVs) in dynamic shallow seas.

Examining the Role of Economic Complexity and Climate Readiness in the Climate‐Fishing Nexus

Sustainable Development, EarlyView.
ABSTRACT This paper investigates the climate‐fisheries association in Gulf Cooperation Council (GCC) nations from 1999 to 2022. A key objective is to explore the role of both the economic complexity index (ECI) and the climate readiness factor (READ) in the climate‐fishing nexus.
