Optimising collection geometry for long‐range synthetic aperture sonar interferometry
IET Radar, Sonar & NavigationInterferometric synthetic aperture sonar (SAS) is a technique to image and map the seabed in very high resolution. For large area coverage rate systems with hundreds of metres swath width, the achievable performance varies significantly over the swath ...

Sonar-Based Simultaneous Localization and Mapping Using the Semi-Direct Method
Journal of Marine Science and EngineeringThe SLAM problem is a common challenge faced by ROVs working underwater, with the key issue being the accurate estimation of pose. In this work, we make full use of the positional information of point clouds and the surrounding pixel data.

Cache‐Cache: Dans les souffles du Grand Fleuve…
Anthropology of Consciousness, Volume 37, Issue 2, Fall 2026.ABSTRACT Between ventriloquism and divination, devotion and consecration, an old and sublime marine game unfolds each day, with living breaths shared in the waters of the great river. In Tadoussac, on the north shore of the St. Lawrence Estuary, at the mouth of the Saguenay, the rumor of whales has long resonated.

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.

Global Evidence for Off‐Axis Flexural Modification of Abyssal Hill Faults at Mid‐Ocean Ridges
Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.Abstract Young oceanic lithosphere flexes as axial topography decays across mid‐ocean ridge shoulders, yet this deformation has been quantified at only a few segments, leaving its global expression poorly constrained. We analyzed 50 across‐axis bathymetric profiles from 21 regions spanning slow to fast spreading rates, identified 1,201 abyssal‐hill ...
