Mussel culture monitoring with semi-supervised machine learning on multibeam echosounder data using label spreading.

Journal of Environmental Management
High diversity seabed habitats, such as shellfish aggregations, play a significant role in marine ecosystem sustainability but are susceptible to bottom disturbance induced by anthropogenic activities.

First Direct Observations of Dilute Antarctic Turbidity Currents Associated With Dense Water Overflows

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Turbidity currents are increasingly recognised as a key mechanism for transporting sediment into the deep ocean, yet their structure, behavior, and long‐term impact in Antarctic submarine canyons remain poorly understood owing to a lack of direct observations.

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 ...

High-resolution multibeam bathymetry of the northern Mid-Atlantic Ridge at 45–46° N: the Moytirra hydrothermal field

Journal of Maps, 2021
This work presents a new high-resolution multibeam bathymetric map of a segment of active deep sea-floor spreading in the Atlantic Ocean, the northern Mid-Atlantic Ridge (MAR) at 45–46º N.

The Effect of the Density of Measurement Points Collected From a Multibeam Echosounder on the Selection of IDW Interpolation Points in the Process of Creating Seabed Models

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The article presents the results of research on the effect of the density of measurement points (depth) from the multibeam echosounder (MBES) on the accuracy of the generated sea bottom models and the effect of this density of points on the optimal ...

Measurement of Seafloor Acoustic Backscatter Angular Dependence at 150 kHz Using a Multibeam Echosounder

Remote Sensing, 2021
Acoustic seafloor measurements with multibeam echosounders (MBESs) are currently often used for submarine habitat mapping, but the MBESs are usually not acoustically calibrated for backscattering strength (BBS) and cannot be used to infer absolute ...

Fluid Pathways and Sources Driving Recurring Pockmark Formation on the Chatham Rise, New Zealand

Basin Research, Volume 38, Issue 5, September‐October 2026.
Quasi‐3D seismic data interpretation and spatial pattern analysis indicate that pockmark formation on the SW Chatham Rise is likely driven by a combination of compaction‐related dewatering during polygonal faulting and silica diagenesis, coupled with deeply‐sourced, possibly CO2‐rich fluids from subducted limestones migrating along prominent basement ...

Surficial Substrate Complexity of the Central Gulf of Maine as Observed Through Video Observation During a Fisheries Survey

Marine Ecology, Volume 47, Issue 5, September/October 2026.
ABSTRACT The Gulf of Maine is a geologically complex environment that supports a high diversity of plankton, invertebrates, and fish, including commercially important species. Its substrate heterogeneity is well known though existing high‐resolution substrate data are limited, hindering effective fisheries management.

Internal Structure and Formation Process of a Giant East Antarctic Grounding‐Zone Wedge

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The marine‐based portions of the East Antarctic Ice Sheet are currently losing mass at an accelerating rate due to atmospheric and oceanic forcing. Assessing these changes requires understanding long‐term grounding‐zone dynamics preserved in glacial geomorphology, including understudied East Antarctic shelf sectors.
