Colour Sonar: Multi-Frequency Sidescan Sonar Images of the Seabed in the Inner Sound of the Pentland Firth, Scotland

Journal of Marine Science and Engineering, 2016
The backscatter response of a seabed to an incident sonar signal is dependent on the carrier wave frequency: i.e., the seabed is acoustically colourful.

DYNAMIC RESIDUAL SEABED RESPONSE AROUND A MOVABLE PILE FOUNDATION

Coastal Engineering Proceedings, 2018
Wave-induced seabed soil response and its resultant liquefaction is common observed in a silt seabed with relative poor drainage condition, which poses a great threaten to the foundation safety of marine structures. Regarding the governing equations, three different approaches namely the Fully-dynamic (FD), Partialdynamic (PD) and Quasi-static (QS ...

Recovery at Morvin: SERPENT final report [PDF]

, 2010
Recovery from disturbance is poorly understood in deep water, but the extent of anthropogenic impacts is becoming increasingly well documented. We used Remotely Operated Vehicles (ROV) to visually assess the change in benthic habitat after exploratory ...

Juvenile and Adult Three‐Spined Sticklebacks Exhibit Different Habitat Use in Shallow Baltic Sea Bays

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Three‐spined sticklebacks (Gasterosteus aculeatus) have become dominant in many Baltic Sea coastal fish assemblages, yet life‐stage‐specific habitat use remains poorly understood. We surveyed shallow water habitats along the coast of Gotland, Sweden, to examine how juvenile and adult stickleback abundances relate to variables such as submersed

Scour‐Conditioned Seismic Fragility Analysis of Monopile‐Supported Offshore Wind Turbines

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 4, Page 947-967, 10 April 2026.
ABSTRACT Monopile‐supported offshore wind turbines (MS‐OWTs) are increasingly deployed in seismic coastal regions, where they face compound risks from earthquake loading and seabed scour. While past studies have addressed these hazards separately, seismic fragility under evolving scour conditions remains insufficiently understood. This study introduces

Numerical investigation of seabed response around submarine buried pipelines considering spatially heterogeneous seabed properties

Applied Ocean Research
Submarine pipelines are critical infrastructure for transporting oil and gas resources in marine engineering. Wave-induced pressure can generate oscillatory and residual pore pressure responses within the seabed, potentially leading to seabed ...

Unfinished Business: a Review of the Implementation of the Provisions of United Nations General Assembly Resolutions 61/105 and 64/72, Related to the Management of Bottom Fisheries in Areas Beyond National Jurisdiction [PDF]

, 2011
In 2006 the General Assembly adopted resolution 61/105, based on a compromise proposal offered by deep-sea fishing nations, which committed States and regional fisheries management organisations [RFMOs] to take specific measures to protect vulnerable ...

Deep Quake Dynamics: A Multimodal Fault‐Aware Approach to Earthquake Magnitude and Occurrence Time Forecasting

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
EQMT integrates earthquake catalog data, fault‐network geometry, engineered features, and graph embeddings in a unified framework for forecasting earthquake magnitude and occurrence time. The framework is designed to reflect inter‐fault spatial dependencies together with temporal seismic patterns, addressing limitations of approaches based only on ...

Discard Survival of Thornback Ray (Raja clavata), Undulate Ray (Raja undulata) and Small‐Eyed Ray (Raja microocellata) in Northeast Atlantic Inshore Fisheries

Fisheries Management and Ecology, Volume 33, Issue 2, Page 355-367, April 2026.
ABSTRACT Quantifying discard survival of species is crucial for effective fishery management. Electronic tags and visual health assessments were used to estimate postrelease survival of commercially caught thornback ray (Raja clavata), undulate ray (Raja undulata) and small‐eyed ray (Raja microocellata) from Northeast Atlantic inshore fisheries ...
