Fine‐Scale Structure and Kinematics of an Active Submarine Strike‐Slip Fault From Micro‐Bathymetric Mapping and Analog Modeling: The North Alfeo Fault Offshore Catania (Eastern Sicily)

Tectonics, Volume 45, Issue 5, May 2026.
Abstract Southern Italy and eastern Sicily have been the site of several destructive historical earthquakes. Here at the junction between the western edge of the Calabrian subduction zone and the Malta Escarpment several strike‐slip faults have been mapped, which may be the surface expression of the lateral slab tear fault and are candidate sources for

Automated Filtering of Multibeam Water-Column Data to Detect Relative Abundance of Giant Kelp (Macrocystis pyrifera)

Remote Sensing, 2020
Modern multibeam echosounders can record backscatter data returned from the water above the seafloor. These water-column data can potentially be used to detect and map aquatic vegetation such as kelp, and thus contribute to improving marine habitat ...

Automated Feature Extraction and Classification of Submerged Cultural Heritage Assets in the Puck Lagoon via Multisensor Remote Sensing

Archaeological Prospection, Volume 33, Issue 2, Page 397-421, April/June 2026.
ABSTRACT This study presents a strong framework for the detection and classification of Submerged Cultural Heritage Assets (SCHA) in shallow marine environments using the integration of multibeam echosounder and airborne LiDAR bathymetry with object‐based image analysis and fuzzy logic–based classification.

Comparing convolutional neural network and random forest for benthic habitat mapping in Apollo Marine Park

Remote Sensing in Ecology and Conservation, Volume 12, Issue 2, Page 275-291, April 2026.
A comparison of Convolutional Neural Network (CNN) and Random Forest (RF) model predictions of benthic habitats within Apollo Marine Park. The CNN (left) and RF (right) classification maps show the spatial distribution of three habitat types: high energy circalittoral rock with seabed‐covering sponges, low complexity circalittoral rock with non‐crowded

Interaction of internal waves with the seafloor on the Namibian shelf (SE Atlantic Ocean): Implications for seafloor geomorphology

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Over geological timescales, internal waves play a significant role in shaping the seafloor morphology. They generate nepheloid layers, slope‐parallel channels and escarpments with erosional surfaces. Abstract The long‐term impact of internal waves on sedimentation and seafloor geomorphology remains poorly constrained.

Millions of seafloor pits, not pockmarks, induced by vertebrates in the North Sea

Communications Earth & Environment, 2023
Seabed pockmarks are among the most prominent morphologic structures in the oceans. They are usually interpreted as surface manifestation of hydrocarbon fluids venting from sediments.

Combining multibeam and single beam echosounders for quantifying gas bubble release from the seafloor

Limnology and Oceanography: Methods, Volume 24, Issue 2, February 2026.
Abstract Marine gas bubble release is a worldwide phenomenon that impacts the local marine ecosystem and contributes to carbon fluxes with respect to global warming. It is still challenging to assess gas flow for large seep areas (tens of km2), but recent advances in calibrating and processing multibeam echosounder (MBES) data make this problem ...
