Assessment of Bottom Trawl Impacts on the Status of Seabed Communities in European Seas

Fish and Fisheries, Volume 27, Issue 2, Page 285-299, March 2026.
ABSTRACT Bottom trawling affects seabed habitats, but its large‐scale impacts remain poorly quantified. Assessment of trawling impacts is essential to support monitoring and achieving sustainability objectives under international conventions, sustainable development goals, and seafood certification programs.

Multispectral Multibeam Echo Sounder Backscatter as a Tool for Improved Seafloor Characterization

Geosciences, 2019
The establishment of multibeam echosounders (MBES), as a mainstream tool in ocean mapping, has facilitated integrative approaches towards nautical charting, benthic habitat mapping, and seafloor geotechnical surveys. The combined acoustic response of the

The estimation of geoacoustic properties from broadband acoustic data, focusing on instantaneous frequency techniques [PDF]

, 2002
The compressional wave velocity and attenuation of marine sediments are fundamental to marine science. In order to obtain reliable estimates of these parameters it is necessary to examine in situ acoustic data, which is generally broadband.

Tide‐Modulated Ocean‐to‐Earth Energy Conversion Quantified With Coastal Fiber Sensing

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Quantifying how incident ocean waves transfer energy into seismic surface waves along the nearshore is essential for understanding coastal hazards and Earth–ocean coupling, yet time‐resolved in situ estimates have been scarce. Here we use a beach‐deployed distributed acoustic sensing array co‐located with an ocean‐bottom node to directly ...

Mackenzie River Freshwater Controls Early Sea Ice Formation in the Eastern Beaufort Sea

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Arctic sea ice plays a critical role in Earth's climate system, and as it continues to thin and retreat, understanding the processes driving its variability is increasingly important. Using satellite data and a coupled ocean–sea ice model, we examined how freshwater from the Mackenzie River influences fall sea ice formation in the Beaufort Sea.

Development of biodegradable composite micro-perforated panel made from natural fibre composites with evaluation of its acoustic and mechanical properties [PDF]

, 2020
Micro-perforated panel (MPP) has been widely considered as a promising alternative for sound absorption purposes. Plenty of research has been done to improve the sound absorption of MPP but no specific work highlights the material structure effect ...

Behaviour of Temperate Reef Fish Species Around Oyster Aquaculture Farms and Natural Rock Reefs

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT Cultivation of eastern oysters using aquaculture gear increases habitat for temperate reef fish. Cunner (Tautogolabrus adspersus), scup (Stenotomus chrysops) and tautog (Tautoga onitis) inhabit a variety of complex natural and manmade habitats, including oyster aquaculture cage farms.

Diffuse attenuation coefficient and bathymetry retrieval in shallow water environments by integrating satellite laser altimetry with optical remote sensing

International Journal of Applied Earth Observations and Geoinformation
Shallow water environmental information is crucial for the study of marine ecosystems and human activities. There have been numerous satellite remote sensing studies focused on this area. However, accurate information acquisition from remote sensing data

Evaluating the Risk of Collision of Seals Swimming Within Metres of Operating Tidal Turbines

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT We used imaging sonar to continuously monitor wildlife at an operational tidal turbine in the Pentland Firth, Scotland, between May 2022 and June 2023. Of 704 detected seal tracks, 347 occurred during turbine operation and 122 of these were detected directly upstream of the rotating blades in the horizontal plane.
